Interesting article, i like the idea of the frog design, i just got CFL’s in my house, but have yet to install them.
Im looking forward to more info on frog design lights.

Great idea...I want to change all bulb in my house with LED bulb whenever it is available in the market. Penny Bright

As long as the right people hear about this, this will be the only lighting source in a few years, as long as people are smart enough to not keep the old kinds of bulbs around, such a simple idea that skipped so many minds, but such a great one

This is a great idea. The biggest issue right now is getting omnidirectional light out of LED's. Absolutely brilliant. Most bulbs trying to accomplish this shoot the light upwards into a diffusing lens - so it only emits light out of the top half of the bulb....like this one: LED Globe Light Bulb

For an LED bulb that looks more or less like a regular lightbulb, uses just a few watts and is available right now, check out the new Pharox LED bulb. Requires just 4 watts of energy to replace a 40-watt incandescent. Prices on this latest generation of LED bulbs are getting more reasonable too… http://tinyurl.com/d2ar8o

Jeff,

I just noticed that two patents filed this year, # 20090002986 and # 20090002979, owned by Cree Lighting address the issue you raised. Basically, they are trying to do what you highlighted as being a concern with LEDs: how to diffuse the lights.

The patents’ description say: “The one or more LEDs are configured to generate light in a first direction to illuminate a first area proximate to the lighting system. The housing is configured to reflect a portion of the generated light so as to allow a remaining portion of the generated light to pass through the housing in a second direction, different from the first direction, and illuminate a second area proximate to the lighting system.”

I like the photos on your website that show the differences between high and low temperature Kelvin LEDs and incandescents. A picture is worth a thousand words. You might want to check out LEDinsider.typepad.com for more on LED developments.

Best, Ellen

Energy efficient light bulbs are the easiest first step consumers and businesses can take towards reducing their energy consumption. Products have gotten light years better in the past few years and, in my eyes, indisputably better for 99% of applications. Both CFL and LED light bulbs run much cooler than incandescent bulbs, use energy much more efficiently, and do offer saving on your electricity bill. I am a vendor of energy efficient bulbs, so perhaps I am a bit biased, but I don’t know why everyone doesn’t switch today. (Superior Lighting Dot Com)
