Amazing Efficiency
The CL-3 Bulb like all EarthLEDs is amazingly efficient. Although it only draws 3 watts of electricity, it performs like a 45 Watt light bulb while at the same time operating below 125 degrees Fahrenheit. The end result is reduced cooling costs and operational safety above and beyond that of traditional incandescent bulbs.
Long Life = Big Savings.
The CL-3 has a life span of over 50,000 hours meaning you will be able to enjoy its amazing light output and energy cost savings for over 11 Years! On the other hand the incandescent that is in its place now will need to be replaced over 50 times in the same time frame.
To put this into perspective:
One - 3 Watt EarthLED CL-3 costs approximately $1.30 to run per year at 12 hours per day. Since it was on for approximately 4000 hours it still has nearly 10 years of life! Throughout its entire 11 year life an CL-3 will cost approximately $35 including the cost of the CL-3, while a traditional fixture using an incandescent bulb will cost nearly $230!
Environmentally Friendly by Design
EarthLEDs are the most environmentally friendly light source other than pure sunlight. First, there are no hazardous substances used inside EarthLEDs. All of our products are RoHS compliant (a strict new standard calling for the elimination of hazardous substances). You've probably heard a lot about Compact Florescent Bulbs or CFL. These have been touted as a solution to the inefficiencies of incandescent yet they are all made with mercury, thus they are hardly an environmentally sound solution after all.
Second, EarthLEDs are part of the solution to the energy crisis we are all facing. EarthLEDs use less power up front and generate less heat when used. Replacing all of your lighting with EarthLED's will suddenly make your home or building an environmentally friendly structure.
Finally, with the long life you will achieve from your EarthLED bulb, you will save on the disposal of approximately 50 incandescent bulbs and 5 mercury tainted, compact fluorescent bulbs thus cleaning up our landfills and ultimately saving our environment from waste.
Light Pure and Simple
EarthLED CL-3 bulbs are available in white and warm light color temperatures for the utmost in flexibility. No matter which temperature you choose, you will always get pure, clear light that makes reading or viewing objects easier on the eyes. Tired of annoying flickering and headaches caused by compact fluorescent bulbs? Say hello to EarthLEDs and their consistent visibility.

User Reviews: EarthLED CL-3 LED Light Bulb
Cons: None so far
I bought one of these 3-watt bulbs as a "try out" for LED bulbs. I liked that it looked like a regular bulb. So far I've been impressed - most people can't tell it from a regular bulb. It disperses the light nicely and has a nice warm tone to the light. Overall I'm very impressed and it doesn't hardly seem possible that I can get that much light out of just 3 watts!
Cons: Cost
Having ventured into the realm of LED lighting and replaced my basement laundry room light with a LED bulb consisting of 36 individual LEDs, I felt the time had come to try a suitable living room light bulb replacement. I leave my small table lamp on 24hrs/day with an 11 watt CFL (40 watt equivalent). After discovering earthled.com, I found they had a reasonably priced ~45 watt incandescent replacement bulb that utilized only 3 watts of power. This bulb incorporates what are called, LED light engines. These high-power LEDs range in size, but are typically 1-2 watt each. This particular bulb, consumes 3 watts of power and uses 3 Cree 1 watt light engines. Think of light engines as little teeny (in this case) 1 watt processors.
The analyze I alluded too above is an important distinction between LED bulbs consisting of amassed individual LEDs and LED light engines. This bulb does produce heat. However, you will only feel warmed on the silver colored band around the middle of the LED bulb. That is because this band serves as the heat sink for the LED light engines. Do not be alarmed, the globe is cool to the touch and you will never be burned or deterred by touching the silver (or aluminum) heat sink band.
Having covered heat output, lets talk about light output. This LED bulb is fantastic. I am very pleased with both the construction and design of the bulb. There is an internal mirror assembly, that couple with the frosted globe, help to disperse light in a near 360 degree manner. This is a great advancement and brings LEDs to primetime in terms of household application. I find the light of this bulb to be pleasant, on par with the color spectrum of the warm white CFL, and near target for 45 watt incandescent light output.
Overall, I am very pleased with this LED light bulb and the cost savings over the lifetime of the bulb are just fantastic. Total cost over the projected 50,000 hr lifetime of the LED bulb is, at $0.10 kW/hr, is $15 for electricity and $29.95 for the bulb. This is a total of $44.95. For a comparable 11 watt CFL, rated at 10,000 hr lifetime, taken over 50,000 hrs, you are looking at a lifetime cost of $69.95 (assuming a $2.99 replacement cost for each of the 5 CFLs).
Since the lifetime of this bulb is roughly 50,000 hrs. You will be able to enjoy this LED bulb for 11 years at 12 hrs/day or 5.7 years at 24 hrs/day (like me!).
Look for the price of this bulb to come down as the technology for the LED light engines becomes more commonplace.
Excellent buy and a great product!
Cons: pricy
