LED Your Light Shine

My favorite green product of the week: EarthLED CL-3 LED light bulb

What is it?
How many Cleantechbloggers does it take to change a light bulb? If it’s changing an incandescent to an LED, only one – because we all know LEDs are the way of the future. The EarthLED CL-3 is a 3-watt LED replacement bulb, which is equivalent to a 45-watt incandescent bulb. It can be used anywhere you use a traditional bulb – even under lampshades (but then you can’t quite as easily make them conversation pieces).

Why is it better?
The CL-3 is not only energy efficient, it also has a life span of more than 50,000 hours. According to EarthLED, that means you’ll have an 11 year relationship with your LED (while in that same time frame, you’d have meaningless flings with at least 50 incandescent bulbs).

Of course, the initial cost of an LED is much higher than for a compact fluorescent light bulb or an incandescent. But have no fear. Over the LED’s entire life, it will only cost you $35, including the cost of the bulb itself and operational expenses. EarthLED compares that to “a traditional fixture using an incandescent bulb [that] will cost nearly $230.” And those costs don’t even take the positive environmental externalities into account like the carbon dioxide saved from all that unused electricity!

These LEDs are also RoHS (Restriction of Hazardous Substances Directive) compliant, so they don’t have any hazardous materials you need to worry about. And because they last so long, you send far less waste to the landfill.

Where can you find it?
You can buy CL-3 bulbs and a variety of other LEDs from the EarthLED store. They are available in warm white and cool white. One CL-3 costs $29.99.

But here’s a little shameless self-promotion. The Green Home Huddle just launched a contest running through Earth Day in which you could win a CL-3 (plus a bunch of other cool stuff) just for writing some green product reviews or wiki articles.

    This bulb says it’s equivalant to a 45 watt incandescent. First correct me but, have you ever seen a 45 watt incandescent? They say it produces 240 lumens, a 40 watt incandescent usually produces 400 lumens. So it looks like another case of over stated comparisons and self promotion sell an over priced “Green” product. How dumb do they think we is? DonsGreenStore.com is a much more honest seller of LED bulbs.

    While doing an electrical upgrade, we were told by the inspector that we have to have dimmers. Also, our bathroom lights and the lights beside the external entrances must have motion sensors.But when shopping for LED bulbs, we often see warnings saying they can't be used with dimmers or motion sensors.Is there any easy way to use LED bulbs while still complying with code requirements for dimmers and motion sensors?
