The Best Green Products of 2009

Welcome to the second annual 1GreenProduct.com roundup of my favorite Green products I had a chance to review in 2009:

Cut on recycled cardboard? You betcha.

1. Epicurean Cutting Boards, particularly those made from recycled cardboard.

2. Sylvania Living Spaces CFL bulbs. Affordable bulbs offering the usual CFL energy savings with better-quality light. What's not to like?

3. prAna's tough but lightweight men's Sutra Pant, woven from a combination of hemp and recycled PET. I have a feeling these pants will last for a long time. I'm pretty impressed with prAna's total clothing line, which incorporates lots of bamboo, hemp and recycled fabric while using quality workmanship and cool designs.

4. Green Pieces affordable, biodegradable puzzles made from recycled paper and implanted with wildflower seeds. Great idea!

5. It wasn't specifically marketed as a 'green product', but after six months of use I'm still super-impressed with the performance, size and especially the energy efficiency of my new desktop PC, the Compaq Presario CQ2009F. Of course, it was so affordable and efficient that Compaq discontinued it (grrrr...) but you can probably find similarly small and efficient PCs from various manufacturers now. If you've been using an older PC and you upgrade to one of these mini desktop machines, you could your computing energy usage by 60-70 percent!

The incredibly efficient GeoBulb-II is now much more affordable.

6. The incredibly energy-efficient GeoBulb-II LED light bulb. Using just 7.5 watts of electricity, the cool white version of the bulb is designed to deliver as much illumination as a 60-watt incandescent bulb. Note that the price of this bulb has dropped by 50% in just five months since I first reviewed this product. It's now somewhat more affordable at $49.95. Meanwhile, the next generation GeoBulb-3 has hit the shelves, costing $99.95, but apparently using a tiny bit less energy (7 watts) to deliver more luminosity and last nearly twice as long (50,000 hours)!

7. A2B Electric Two-Wheeler. I rode several electric bikes in 2009. If price were no object, this is the one that I would buy. It was the most fun, the best-looking and offered the most comfortable ride. (If you look around a little, it seems like some dealers are now offering the A2B for a few hundred dollars under MSRP - i.e. around $2500.)

8. Reynolds Wrap 100% Recycled Aluminum Foil - works just as well as the non-recycled kind, but requires much less energy to produce and keeps trash out of landfills. Brilliant.

9. Soft, comfortable, durable and eco-friendly bamboo clothing from Ivee. For yoga, fitness or just lounging around, Ivee Bamboo Clothing has got you covered.

10. Dr. Oetker Organic Muffin Mix and If You Care unbleached baking cups. A muffin mix on the top 10 list? Oh yeah, these are some tasty eco-friendly muffins :)
And that's all folks for 2009. Have a very merry holiday season and a wonderful New Year's celebration. I'll do my best to bring you reviews of lots more exciting Green products in 2010.

Meanwhile, if you have any suggestions for making this site better, please don't hesitate to get in touch. I welcome your ideas for making 1GreenProduct.com even better in the year ahead.

Thank you for reading and for caring.

GeoBulb LED light bulb

GeoBulb II by C. Crane
GeoBulb II by C. Crane


You might look at the GeoBulb® II design as being sexy and sculptural.

Or it may look a little exoskeletal to you.

But either way, it is the low energy consumption of this LED light bulb that should really catch your eye.

In its Cool White form, the GeoBulb II delivers claims to deliver approximately the same illumination as a 60-watt incandescent light bulb while using only 7.5 watts of power! That's almost an 87% energy savings!

With a projected life span of 30,000 hours, GeoBulb II's manufacturer C. Crane says the bulb should last for 10 years of 8-hours-per-day usage. The bulb also comes with a comforting 3-year warranty.

As for the light quality, like many LEDs, the light is very white, with almost a bluish tint. That may sound unappealing, and you probably wouldn't want to use the GeoBulb II for mood lighting, but the fact is that the GeoBulb II is actually fantastic for use as a reading light. Somehow it makes reading printed materials much easier and seemed to reduce eye strain, at least for me.

GeoBulb II by C. Crane

(If you don't want such a blue-white light, C. Crane does sell Soft White and Warm White varieties of its GeoBulb II bulbs, but those are only rated as equivalent to 50-watt and 40-watt incandescent bulbs respectively. We presume these other varieties have some sort of coating on the bulb that 'softens' or 'warms' the light but also cuts down on blocks some of the luminescence.)

The only drawback I can see here is still price. Even after a 15% price reduction, the GeoBulb II will still set you back $99.95. Yowzers!

It's true that the GeoBulb II will save you a lot in energy costs over the long run, but it's still hard to imagine too many folks shelling out $100 per bulb when it's possible to buy a 12-pack of Sylvania CFL bulbs at Amazon for around $24. True, the CFL bulbs use almost twice as much electricity (13 watts) as the GeoBulb II to produce the same amount of lumens (60-watt incandescent equivalent), but on the other hand the GeoBulb II is about 50-times more expensive.

How many light bulbs do you have in your home? I have about 15 in my apartment. That means I could light the whole apartment for $48 with the Sylvania CFLs and have plenty of leftover replacement bulbs. Or I could light the apartment for $1500 with GeoBulb IIs.

$1500 vs. $48. I love the GeoBulb technology - and LED light bulb technology in general - but it's going to have to come down in price to penetrate beyond the millionaire/billionaire demographic.

Hopefully, LED bulbs will get more affordable. Most technology seems to progress down an affordability curve. Only a few year ago, CFL bulbs were rather pricey too. Now they're easily affordable. Hopefully in a couple of years, we'll be seeing multipacks of GeoBulbs for a fraction of the current price.

Where to Buy:


If your recession-era budget doesn't have room for the GeoBulb II, remember that you can still get a Pharox 4-watt LED (40-watt incandescent equivalent) at Amazon for $34.99 or the EarthLED ZetaLux for $49.99 (6-7 watts of power consumption, 50-60 watt incandescent equivalent).

Eco-Travel - Nashville (Hutton Hotel, aloft Nashville-Cool Springs)

Last month, I had the pleasure of taking a trip to Nashville, Tennessee. What a fun place! From its beautiful countryside and charming residents to the thriving music scene, Nashville makes an excellent, affordable vacation destination.

But how about from an eco-travel perspective? Well, I didn't have time to bike around Nashville, but I did see quite a few bike lanes and they were getting some use by the locals.

My initial assessment is that the existing bike paths will need to be expanded and connected to give Nashville a true alternative to car commuting, but the city is compact enough that a better bike infrastructure could make Nashville a wonderful biking city. Nashville does have a Strategic Plan to create an integrated bikeway network, so hopefully the system will become more comprehensive in the years ahead.

I didn't have a chance to ride public transit either, but the uncrowded buses seemed to run pretty frequently.

There is no light rail within Nashville, but a rail line (the Music City Star) recently started service from Nashville to points east. The downtown Nashville station looked spiffy and new.

(For what it's worth, I don't think it would make financial or logistical sense for a city the size of Nashville to put in light rail, but a trolley system of the sort prevalent in Vienna or Prague could work quite well here.)

Eco-travelers have a couple of exciting options in terms of lodging when visiting Nashville. Right near Vanderbilt University and convenient to Downtown is the Hutton Hotel, which just opened earlier this year. The Hutton has some serious eco credentials having just hosted the North American Summit of former Vice President Al Gore's Climate Project.

Built inside the completely gutted and renovated shell of a former office building, the Hutton is chock full of eco-friendly amenities. For instance, the lobby and guestrooms use bamboo flooring and furniture. Interior and exterior lighting uses energy-efficient LED and compact fluorescent fixtures. Remarkable Kone EcoDisc elevators use a low-friction, gearless design to reportedly achieve 70% energy savings over traditional elevators.

Dual flush toilets in the guestrooms (designed by a local company called Baden Bath) and waterless urinals in the public restrooms help save water. Soap dispensers in the guest rooms cut down on the use of plastic bottles.

Hutton employs the key card system prevalent in Europe where guests must insert a card into a slot when entering their guestroom in order to active the room's lights. When guests take their card on exiting the room, the lights automatically shut off 30 seconds later, saving even more energy.

Meanwhile, the hotel's restaurant 1808 Grille has gotten rave reviews in the local press. The restaurant has made a commitment to serve locally-produced wines and beers and Whole Trade coffee (from Allegro Coffee Company, which also provides organic tea bags in the Hutton's guest rooms). I believe the restaurant also places an emphasis on sustainable seafood and using organic ingredients when possible. Some of the restaurant's furnishings involve the use of reclaimed wood, saving natural resources.

While it's certainly possible to walk from the Hutton to Vanderbilt and even to Downtown Nashville, the Hutton also offers a hybrid courtesy car for use within 3 miles of the hotel. That 3 mile range easily covers trips to the convention center and nightlife in the downtown District.

Meanwhile, for Nashville visitors who prefer a bit of distance from the downtown hubbub, the Aloft-Nashville Cool Springs hotel located about 20 minutes south of the city offers another good eco-friendly option.

Owned by Starwood and associated with the W Hotel brand, Aloft Cool Springs has a number of eco-friendly touches including the use of cork building materials, sustainably-sourced wood venees and in-shower soap and shampoo dispensers (cutting down on the use of disposable plastic bottles). Various online sources indicate that Aloft hotels use biodegradable, eco-friendly cleaning products both within the rooms and on the hotels' pools.

If you do choose to stay at the Aloft Cool Springs, you'll be right nearby the town of Franklin, recently honored by the National Trust for Historic Preservation as a 2009 Distinctive Destination.

One more note for bicyclists - the area near Nashville is home to the northern terminus of the Natchez-Trace Parkway, a 444-mile road maintained by the National Park service that offers a beautiful and relatively safe bicycling option from middle Tennessee to the far Southwestern corner of Mississippi. We wanted to bike a little bit of the Parkway, but ended up only having about 30 minutes to drive a tiny piece of the road. In that time, we saw only about five cars and an equal number of bicyclists. Seems like a lovely route for long-distance cyclists.

PS - Nashville has a great zoo that helps spearhead conservation efforts for endangered animals like the clouded leopard. In addition, I was surprised and pleased to find out that zoo's cafeteria  has eschewed petroleum-based plastics in favor of renewable and biodegradable plates, cups and utensils made from such materials as sugarcane, corn and potato! Handy signs (like the one pictured in the unfortunately dark photo above) explain to zoo visitors that all plates/cups/utensils are compostable, biodegradable and designed to 'return to nature' in 45-60 days. Pretty cool.

Sylvania Living Spaces CFL bulbs + DOT it LED lights

I'm a big fan of CFL bulbs.

How can you not like a product that uses 1/4 of the electricity of incandescent bulbs to cast the same amount of light? Using less energy not only saves money, it also reduces the demand on the electrical grid and lessens the urgency of building new power plants.

Add in the fact that CFL bulbs are rated to last around 12-times longer than incandescents (approximately 12,000 hours for CFLs versus 1,000 hours for incandescents) and the argument in favor of CFLs becomes even stronger.

Many hotel chains and stores have recognized the benefits of CFLs and made the switch. So why are some consumers holding back?

1) Price. CFL bulbs used to be much more expensive than incandescents, but prices have been falling. CFLs will still cost more at the register, but when you factor in replacement costs and energy savings, CFLs definitely make sense from a pocketbook perspective.

2) Mercury. This is a valid point. Mercury is an extremely hazardous substance and CFLs do contain mercury while incandescents don't. On the other hand, CFL manufacturers have been working hard to reduce the amount of mercury in their bulbs. Last year, we covered the Sylvania Micro-Mini Twist, which contains just 1.5 milligrams of mercury. For comparison sake, we linked to Gaiam, which pointed out that the old mercury thermometers many of us used to use in our homes contained 500 milligrams of mercury. Still, you do need to be careful if a bulb should happen to break (PDF) and you can't just dispose of the bulbs by throwing them in the trash when they do eventually wear out. You wouldn't want that mercury to leak into a landfill. Fortunately, many major retailers have programs to accept old CFL bulbs free of charge for proper disposal.

(Here's some more info from TreeHugger and the US EPA on what to do if a mercury-containing CFL bulb breaks in your home.)

3) Light quality. This is the big one for many people and it's one with which I can sympathize. CFL bulbs have been belittled for having an unpleasantly cold or bluish light. Personally, I think these concerns have been a bit overblown too, but if you've been worried that CFLs will plunge you into depression, fear no more. Sylvania has recently come out with a new series of Living Spaces(TM) CFL bulbs that provide what Sylvania (accurately) calls "Cozy, Comfortable Lighting(TM)".

Honestly, I didn't realize that my old CFL bulbs were not cozy or comfortable, but when I swapped in the new Living Spaces 23-watt bulbs (slightly fewer lumens than a 100-watt incandescent), I immediately noticed the difference.

Frankly, the new bulb did perk up my demeanor and make me want to skip around the apartment a little. Yep, it was like having a cheerful petit ball of sunshine in my home.

I also liked the fact that the packaging is made of 100% recyclable paperboard.

By the way, in case you're wondering how Sylvania gets such a warm light from its CFL bulbs, the company attributes the difference to "enhanced phosphors".

Note that these new Living Spaces bulbs still have the small dimensions of the Micro-Mini Twist. They also still contain less than 1.5 milligrams of mercury each, according to Sylvania.

Caveat - Sylvania warns that these bulbs are not designed to be used in dimmable lamps, but if you have a lamp with a dimmer, Sylvania has introduced a new line of Mini Twist Dimmable bulbs.

FYI, Sylvania doesn't just make CFL bulbs. In fact, the company has taken the exciting step of introducing a number of LED-powered lighting solutions. Since LEDs are even more efficient than CFLs (i.e. use less power to produce an equivalent amount of lumens), this is an exciting step.

LED bulbs are still rather expensive, but we had a chance to test two Sylvania LED products - the DOT-it(R) Solar and the DOT-it Linear Swivel.

As the name suggests, the DOT-it Solar is solar-powered. Sylvania has very cleverly designed the light with a suction cup so you can stick it your window where the solar-panel will suck up plenty of power to help the 3 LEDs shine for a long time.

The DOT-it Linear Swivel runs on batteries (three AAAs) and can be mounted in numerous ways (velcro, magnetic, adhesive) under a cabinet, in a garage or anywhere else you might need some really bright, tightly-focused light. And here's an idea: you can use rechargeable AAA batteries to reduce landfill waste and make your lighting even more efficient!

These DOT-it products seem like a nice option if you need a bit of extra light someplace and want an efficient solution that doesn't involve any wiring.

Incidentally, the DOT-it Linear Swivel features a very cool on-off mechanism where you lightly run your finger over a "touch sensor" to control the light. Not exactly sure how that works, but it is (as they say in California, "hella cool").

Also, a slight warning about the power of these LEDs: Don't look directly into the light. The DOT-it Swivel is meant to shine down onto a countertop or workspace, but while testing it, I had it pointed up so I could examine it more closely. I accidentally looked at the light saw spots for a while afterwards. Conclusion - these puppies are bright.

Where to buy:

Shop the Sylvania online store for a full selection of DOT-it lights including the DOT-it Solar ($14.99) and the DOT-it Linear Swivel ($9.99).

Sylvania says the Living Spaces bulbs are available at Lowe's ($13-15 for 2-pack), but we were unable to find them in Lowe's online store. Call your local Lowe's store to see if they bulbs are in stock.

You can also find many Sylvania DOT-it products (complete with customer reviews) at Amazon.com.

Pharox LED light bulb


Last October, we reviewed the EarthLED EvoLux(TM) bulb and praised it for using just 13-watts of power to deliver the same illumination as a 100-watt incandescent bulb.

As that EarthLED review mentioned, there's lots to like about LED bulbs:

  • No mercury (unlike CFLs)
  • Very low power consumption for significant luminance
  • Very long lasting - approximately 50,000 hours compared to say 750 hours for a 100-watt incandescent bulb.
  • Relatively cool to the touch since the energy produces light, not heat. So LED bulbs are great to use in hot climates when you don't want your indoor illumination adding strain to your air conditioner.
The only thing we didn't like about the EarthLED bulb was the cost. A single bulb would put an $80 dent in your wallet.

That's why we were thrilled when Lemnis Lighting, a Dutch company, sent us information on its Pharox LED bulb. This 4-watt LED bulb is designed to replace a 40-watt incandencent.

That's right - Pharox offers 90% energy savings over your old incandescent filament bulb, plus all the other benefits listed above. Pharox has a friendlier sticker price too - only $34.95 through Amazon.com.

Now, $35 is still a lot for a bulb, but if your one Pharox LED bulb lasts as long as 50 incandescent bulbs (which Lemnis claims it should), you'll probably come out ahead financially in the long run while saving tons of energy in the process.

Indeed, Lemnis asserts that if every American household switched four 40-watt incandescent bulbs to Pharox 4-watt lamps, American would save $113 billion in energy costs over the lifetime of the Pharox bulbs.

And now for a few caveats:

  • A 40-watt bulb may not be sufficient for your needs. We installed our sample Pharox LED bulb in a small closet/hallway area and found that the bulb casts enough light for us to choose towels and rummage through our medicine bin, but just barely. We're hoping that Pharox comes out with a 6-watt replacement for a 60-watt incandenscent...
  • The light is very white. A comment on Amazon describes the light as greenish. I wouldn't go that far. In fact, you might think of the Pharox light as a sort of 'heavenly glow', the sort of light in which seraphim might bathe. Or you might just think, "Gee, that's some darn white light."
  • Some folks complain that CFL bulbs take a fraction of a second (or longer) to turn on after the switch is flipped. We didn't have that problem with the Pharox bulb, but strangely it did seem to take a smidgen of time to turn off after we flipped the switch. Either that or our eyes are playing tricks on us, which is totally possible.

Where to buy:

The Lemnis website directs consumers to Amazon.com, as mentioned above, where a 3rd party retailer sells the bulb for $34.95.

P.S. - For what it's worth, EarthLED now apparently offers a ZetaLux 7-watt LED bulb that claims to offer illumination comparable to a 50-60 watt incandescent bulb. The bulb is priced at $49.99 and offered in either cool or warm styles. Bulk pricing lets you lower the per-bulb price if you're willing to buy four or more ZetaLux bulbs at a time.

Mr. Beams Motion Sensor Stair Light

We swear that we are not reviewing the Mr. Beams(TM) Motion Sensor Stair Light ($24.99) simply because the product nearly shares the same name as British comedian Mr. Bean (a.k.a. Rowan Atkinson). 

(With or without lighted stairs, we suspect Mr. Bean would take a pratfall...)

But for the rest of us, Mr. Beams could be a lifesaver or at least quite a handy eco-friendly convenience.

Basically, as the name suggests, the Motion Sensor Stair Light is a safety light intended to provide temporary light when needed to help in navigating stairs or other dark areas.

The product attaches to a wall using either double-sided tape or screws (both included). During the day or when the room is illuminated, the light conserves its battery power by remaining dark. When a light sensor detects that the area is dark, Mr. Beans automatically lights up with a low glow. Then when a motion sensor detects further light is needed, Mr. Beans ramps up the brightness and provides a beacon for up to 20 seconds or 1 minute (depending on the setting chosen).

Generally speaking, we're very impressed with the Mr. Beams Motion Sensor Stair Light, though we do have a few reservations. First the good points:

  • In our unit, the light sensor and motion sensor worked splendidly.
  • We were very impressed with the brightness of the LED at even the low-glow setting. When the light detects motion and amps up the brightness, the light is practically dazzling. That's mighty impressive for a very small bulb, but Mr. Beams says that it's using the latest LED technology -- 12-times brighter than standard LEDs.
  • Mr. Beams does seem very convenient. No wiring is required. The batteries are supposed to last for approximately $1 year. Basically, the light strikes us as a very efficient (and thus eco-friendly) device. It's even supposed to be waterproof if you want to use it outdoors (although the Mr. Beams Spotlight might be better suited for that task).

Still, in the spirit of constructive criticism, we don't think Mr. Beams is quite perfect yet. Here are a few observations we hope that Mr. Beams can take into account for the next edition of its stair light:

  • Internal controls aren't very convenient. Maybe it's necessary from a weatherproofing standpoint, but the switch that toggles the Stair Light between 20 seconds and 1 minute of illumination are located inside the device. If you want to change the setting, you have to unscrew the back (easily done with screwdriver or even a coin), remove all three C batteries and then struggle to read the tiny letters around the tiny switch.
  • The switch is a little inscrutable. On the 20 second setting, the lamp really did seem to stay bright for 20 seconds when motion activated. On the 1 minute setting, it never wanted to go off. We waited several minutes (without moving) and then turned on the lights so that the light sensor would switch off the light. We would prefer the 20 second setting anyway (it's certainly long enough for most people to go up or down a flight of stairs or even go into the bathroom at night for a drink of water), but if you want to use the 1 minute setting, that's something to be aware of.
  • The C batteries are a bit bulky and make the unit a little heavy. Also, we had to go online to make sure that it's possible to buy rechargeable lithium ion C batteries and a C battery charger. (It is.) We wish that Mr. Beams could make a smaller, lighter unit that used AA batteries - the type commonly used in digital cameras and many other electronics. We'd even be willing to recharge the batteries more frequently (every 3-6 months?) if we could have a smaller unit.

Still, overall, we're impressed with Mr. Beams. The company has given us even more enthusiasm about the bright future of LED lighting. Perhaps that's not quite as funny as Mr. Bean, but much more illuminating.

Where to Buy:

Order directly through the Mr. Beams website or via e-tailers like Smarthome and Amazon.com.

EvoLux EarthLED

We love Green products that let you maintain or improve your quality of life while reducing the quantity of energy, water or other resources that you consume.

That's why we have long advocated the switch from incandescent bulbs to CFL bulbs like the Sylvania micro-mini Twist. It's also why we're thrilled to find that the latest generation of water-saving showerheads (like the one from Moen that we reviewed last month) do such a great job of giving you a satisfying shower experience while potentially reducing your water use by 30%.

One of the nice things about technology and competition is that companies are always looking for the next big improvement in efficiency that will make their products stand out from the pack.

In terms of lighting technology, the next Green frontier is clearly LED light bulbs.

We had a chance to test the new EarthLED EvoLux™ bulb. Billed by its manufacturer Advanced Lumonics as "The World's Most Advanced Light Bulb", the EvoLux bulb apparently uses just 13 watts of power to create the same light output as a 100-watt incandescent bulb.

For comparison sake, let's note that Sylvania recommends using the 23-watt version of its micro-mini Twist in order to replace an old-fashioned 100-watt incandescent bulb.

According to these figures, switching all your bulbs from incandescent to CFL would deliver more than 75% energy savings, while switching from CFL to LED would yield more than 40% additional energy savings (or better than 85% energy savings in comparison to the original incandescent bulbs).

Furthermore, LED bulbs have a couple other benefits over CFLs:

- CFL bulbs contain mercury. LED bulbs like the EvoLux are mercury-free. (It should be noted that CFL bulbs don't contain very mercury as explained in our post on the micro-mini Twist, but of course zero mercury is better than a little mercury in a household product.)

- Drop an incandescent bulbs and it will shatter. The same thing will happen with a CFL. By contrast, Advanced Lumonics says its LED bulbs will not shatter. Less shattering is a good thing in our book.

- LED bulbs should last longer than CFL bulbs, which themselves last longer than incandescent bulbs. I couldn't find an authoritative average lifetime figure for a 100-watt incandescent, but apparently such bulbs are so inefficient that they've actually been banned by the U.S. Congress. Still, the ban has not apparently taken place quite yet since Lowe's still carries 100-watt incandescent bulbs with a rated lifetime of 750 hours. The 23-watt CFL has an advertised lifetime of 12,000 hours. The LED does even better - Advanced Lumonics claims its EvolLux bulb will provide more than 50,000 hours of illumination!

- LEDs are cool. Literally. Incandescent bulbs use most of their energy making heat, not light. As a result, a 60-watt incandescent in a metal lamp creates a serious burn hazard. By contrast, the same fixture is cool to the touch when housing the 13-watt EvoLux bulb.

So why isn't everyone rushing to the store pell-mell to switch over to LED bulbs? Why aren't we all slashing our lighting energy bills by more than 85%?

In a word: Cost.

You can buy a two-pack of those pretty much disposable (and thanks to Congress, endangered) 100-watt incandescent bulbs for $2.38. That's $1.19 per bulb.

CFL bulbs have come down in price nicely over the past few years, but a two-pack of the 23-watt micro-mini Twist bulbs from Amazon will still set you back $13.75 or about $6.88 per bulb.

Are you sitting down? Good, because we don't want you to fall over when you hear that the 13-watt EvoLux S bulb will set you back $79.99 (and that's on sale from its previous price of $99.99)!

Now, you'll certainly make some of your upfront cost back in lower energy costs. Advanced Lumonics claims that the EvoLux S will cost you less than $6 per year (though we're not sure how many hours of illumination that assumes...). But even knowing that your LED bulb will last practically forever and that your energy costs will be miniscule, it's still challenging to plunk down so many Yuppie Food Stamps for a light bulb.

If I were a rich man, I'd not only "biddy biddy bum" all day long, I'd also go out and buy some EarthLED EvoLux bulbs for every room in my chateau.

But since I haven't come into money just yet, for now I'll have to settle for a single LED bulb that lets me see just how bright the future might be.

("How bright is the future?" you ask. Why, of course it's so bright that I've gotta wear shades.)

Where to buy:

You can order the EvoLux bulb (with or without dimmer capability) directly through the EarthLED website or through ThinkGeek.
