USMB Republicans have been critical of LED bulbs insisting they are two expensive.
95% of the energy used by an incandescent bulb is converted to heat, the remaining 5% is light. Run a 60 watt incandescent bulb for 10 minutes and then unscrew the bulb by hand. What do you feel?
Run an LED bulb that's comparable for 10 minutes and then unscrew the bulb by hand. Feel any heat at all?
LED bulbs last 50 times longer.
Just saw an add on TV for four 60 Watt comparable LED bulbs for $4.99..
That brings the cost of LED bulbs in line with the cost of incandescent bulbs. As LED bulbs are used more and more, the cost will continue to decline. How many lights in your house?
New "Light Recycling" Incandescent Bulbs Could Outperform Energy-Efficient LEDs
But all is not lost. Scientists are figuring out a way to recycle the heat which might eventually make incandescent bulbs more efficient.
