Comment at www.ecogeek.org to get a chance at a free Evolux S! EcoGeek.org shows the difference between incandescent, CFL and LED light bulbs in light quality, brightness and (of course) energy use.

I totally agree with several of the other posters here — CFLs are NOT good for the environment. CFL bulbs contain mercury, a powerful neurotoxin which poses serious health risks, especially for children. Already, researchers have linked mercury toxicity to birth defects, autism, Alzheimers, Parkinson’s Disease, multiple sclerosis, fibromyalgia, lupus, chronic fatigue syndrome, arthritis, depression, bipolar disorder and other conditions. EPA classes them as toxic! Read their warnings.
They glow slightly from the residual power in the unit- it goes away after a few minutes or so. They are much cheaper now- I have been picking up some different models and the spotlights seem to be very nice at higher outputs- the LEDs meant to replace C12-type candle-style small bulbs are pretty pathetic though.
@jdoscher No no, this one glows forever – until the next time it is turned on. I have even put 7 days between switch-ons (when I recently went away for the holidays). I searched it on Google and people say it’s because even though the circuit is totally off, the fixture may be wired so the white wire (hot/common) is wired to the fixture, when it’s supposed to be wired to the switch. (for light sockets it never really matters). But how it gets power from no circuit still boggles me tho
Is the fan inside the übarbulb replaceable? I think it will break before the LED’s burn out.
Meh… I’ll wait until they figure out something better than a cooling fan… also I’ll let you early-adopting nerds take the hit on the economies of scale.
DAmn you;re annoying
@GrannyGamer Coal-fired power stations emit mercury – and during the average 5 year life of a CFL bulb the electricity generated to power it will have lead to smokestack emissions into the atmosphere of 2.4mg of mercury. Over the same 5 year period the electricity consumed by incandescent bulbs will result in 10mg of emissions. Therefore, even if you factor in the 4mg of mercury contained in the CFL bulb itself, the CFL is still a net winner.
i want to get a hammer and break those glasses
this guy isn’t a real geek believe me i know we geeks could give a shit less about how eco friendly the lightbulb is and more about the money
Try decaf.
Do NOT buy the expensive Evolux light bulbs (the one at the end with a cooling fan inside)
They are JUNK. Sure they are bright, while they work. I bought two of them. One pooped out after a couple weeks and my other one just pooped out yesterday (after about a year) from switching it on and off a couple times. The fans on these things die FAST and the hot super LED inside gets fried. Terrible light bulbs that shouldn’t even be allowed to sell! Get one with no moving parts.
or you could just make your own and space the LED farther with no need for a fan for less than 15$
not changing light bulbs is bad for business.
expect intentional design flaws and massive marketing campaigns.
the best way to build a business is to have a great product that your customers will rave about to everyone they know.
I doubt anyone who is trying to build their reputation is going to sabotage their own product.
I am one step ahead of you all. I got rid of light bulbs all together and just use night vision goggles.
nice…u should advertise some, youd be a millionaire by now
Global warming is stupid…what happens when we buy these things is we supposedly save money on our electricity bill. What happens? The electric company will raise your electricity rates to continue paying their employees! So what happens is you spend $40 on a LED light bulb but eventually you will pay a higher electricity rate when they start losing revenue.
I believe the consensus now is to build a darker and even darker light bulb to save energy, pretty soon you could go “Lights Out” for maximum energy savings
hahahahahaha im gonna show this to my entire 8th grade class. they’ll love u
Cool video!
I liked the video and if I get a free buld it will save me from buying 4 instead if five.
@squirrelbong
ironically, I saw an add where David Suzuki was encouraging people to use CFL’s
Last bulb is stupid. That fan is going to burn out fairly early, causing the LED chip to overheat and fail early as well.
I have a place in the desert of west Texas and just got my 403 wind charger running and about 100 watt solar panel and just starting to get into LED lighting as i have enjoy a first generation LED that runs opn 12 volt and use many color LED to get the light light hum that the way they did it but it a great light and now learning more about the new generation LED light bulbs wow they are so cool
Of course the ultimate solution is to build and live in reasonably sized homes which require less lighting because there is less space to light.
