13W LED Bulb Replaces 100W Incandescent
by Sami Grover, Carrboro, NC, USA on 04.22.08
Back in 2007, our post on a 9W LED replacement for a 70W incandescent generated a huge amount of interest and debate. While some were excited to see the dawn of a new lighting technology, others felt it was overpriced and under-powered, in terms of lumen output. We wonder, then, what our readership will make of the new EvoLux 13W LED bulb, which the manufacturers claim will replace a 100W incandescent, or a 13W CFL, and can apparently last as long as 50,000 hours (for comparison purposes, this CFL manufacturer claims that an incandescent will last 750 hours, and a CFL will last 10,000). The price point is still high, coming out at a whopping US$109 (though it is currently on sale for $95), but for those early adopters who just hate changing light bulbs, this might be worth a try. More from the manufacturer’s website:
“Presenting EvoLux, the most powerful direct replacement LED Light bulb available. Using a breakthrough light engine, the EvoLux allows for the first time, the opportunity for every general lighting application to be replaced with an LED light bulb. No more hassle and worries about breaking CFL's, no more wasted electricity on inefficient incandescents, take the leap to the next generation in lighting with EvoLux.
In order to create an LED light bulb that can compete head to head with both CFL and high wattage incandescents, we started with the latest generation CREE light engine. We then added a revolutionary active cooling system that employs a silent internal fan to cool the heatsink. The entire housing is encased in ABS plastic to always ensure that the body of the EvoLux is cool to the touch. Combining these technologies allow us to run the LED light chip at a high enough power output to provide amazing, room light that will fill a room.”
We’d love to hear from anyone who takes the plunge and tries one of these out! In the meantime, take a look at our guide on How to Green Your Lighting.

I've been using LED lights for a while and I love them. I don't see the advantage of this light over the direct replacement I have (http://ledlight.com/detail.aspx?ID=27). I also have a few floods (http://ledlight.com/detail.aspx?ID=145) and even some small bulbs for my fridge (http://ledlight.com/detail.aspx?ID=52)
That LED light does not replace a 100W incandescent: their own literature says the light emits only 900 lumens, comparable to just slightly more than a 60W incandescent. They are being disingenuous to claim such, but sadly this is a common approach with LED lighting and the issue of angle of output. How many people will buy into this only to drop back to incandescents because the claims don't match the reality?
Same power consumption as the CFL, 5 times the life, but 30 times the cost.
You'd have to really hate changing bulbs to pay a $90 premium just to avoid it.
I've switched in the last year, from CFL's over to LED bulbs in baby steps. Yes, there initial costs are very high.
But what was significant was that as we invested $60 - $100 to purchase 1 LED bulbs per mo., each month our electric bill dropped by $20 bucks.
Our house is all electric - no gas at all. Our electric bill has drop down to just $66 per month operation of a four floors in the spring, summer, fall months.
With 7 more lighting fixtures to replace this year, our electric bill should drop to nearly nothing. That's the value of LED bulbs.
We brought our LEDs using the earthtechproducts.com webportal

The Green Home Huddle was actually the first site online to publish the news about the Ecolux. Earth LED just donated $400 worth of LED light bulbs to their contest. I don't think anyone has reviewed the Earth LED Ecolux LED light bulb but hopefully someone will soon. Probably won't be me, since I can't quite shell out $75 for a light bulb...but hopefully soon!
It seems like it will be a hard sell to the public. CFL have a bit of a price advantage. So it will take about 66 or 67 regular 60W bulbs to replace one of the EVO bulbs, and 5 of the CFLs. At about $1.25 for a regular light bulb you are looking at $83, and $12.50 for the CFLs of the 50,000 hours. Then we look at what the electric company would charge. Mine charged me $0.125127 per KW for generation, distribution, and transmission last month. The regular at 3000KW is going to cost about $375.41, and the 13W bulbs are $81.34. So roughly all together to run the different bulbs for 50,000 hours INC - $458.41, CFL - $93.84, and EVO - $190.34. In the eyes of a money concerned public, the CFL is going to win.
@ Peter...
Yes, but, *no mercury* or other hazardous materials to dispose of in 10K hours. So in effect, 5x less hazardous waste.
I know a supplier specially provide led light bulbs,the website is www.oled-lights.com.It looks like they sell mainly led bulbs with e27,mr16 and gu10.
Now high power LED bulbs are still two expensive,but some 1x3w OR 3x1Watt LED Light bulbs are already not that expensive.
It's only about 8-12USD for a 3Watt LED light bulb ,coz i have inquired from that web before.
Let's also consider that there is the "Heat" that is produced from the CFLs (and certainly the regular incandescents). Although this may not be an issue in the colder months, in the summer months that may mean running a cooling device (Fan, A/C, etc.) more to dissipate the excess heat. I realize it may be trivial, but it's still a factor.
Also, since my comments are coming in much later than the others, it's worth noting that the evolux bulbs are as low as $79.99 from http://store.earthled.com/collections/earthled-evolux
I do have other LED lights that are only equivalent to about 25 Watt incandescents and they are ok. My experience with CFLs however, have been less than pleasant. Where they promise lifespans of 2 to 5 years (Depending on Manufacturer), in real life, I am lucky to get a YEAR out of them. So much so, that I started marking the bases of the CFLs with the installation date. So when you figure that cost.... Maybe the LED bulbs are still worth the expense.
As a last note about CFLs, most will have a reduced life, when put into "Enclosed" fixtures because the heat will damage the CFL, where incandescents are much more tolerable to the heat. I don't know about you , but most of my lights are in some type of enclosure. Recessed Lights, Lamp Shades, Porch Lights, etc.... Who, generally just puts their lights out in the open without some sort of shade (decorative or otherwise).
I think I will take the plunge and start of with one (or two) and see how it goes.
