I heard years ago that the electric companies had the patent for white LED's and figured it was about time for them to make a product that would bring them some profit,,, :confused:
-
No one has a patent on white LEDs. They have been used in flashlights for years. The reason why they have not replaced the 60W lightbulb is because they are expensive ($50+), and they give off a noticeable blue hue which drives most people nuts.
-
I know about 6 months ago some researcher found a way to replicate daylight with LEDs. I just overheard it on the news, can't link anything. This may be a bi-product of that same breakthrough.

first those crappy fluorescent swirly bulbs that cost 7 dollars now this? I'll take it!

If it can fry a steak, or melt a person like a layzur, im all for the price. :rock

I didn't do a comparison versus the new fluorescent bulbs but:
Standard 1500 hour, 60 watt light bulb will use $173* worth of electricity over 3 years of continuous use, and will require 18 bulbs = $182 over three years.
$120 LED light bulb in your link will use $23* worth of electricity over 3 years of continuous use = $143 over three years. So, for every fixture in your home, you would save $40 over three years of continuous use.
So, ultimately, even though the LED bulb is much more expensive up front, it is much more cost effective than the standard incandescent bulb.
*based on a $.11/kWh average in 2008
