Hi again,
I Have a question or two on LED lighting, like the new bulbs that can replace your incandescents or CFLs.
My electronics theory is all over the place lately, so maybe I'm just not thinking right...but...
How is using LEDs more efficient? Doesn't a lot of power have to get wasted when the voltage is converted to DC and stepped down to a low running voltage? You'll notice that about half of the bulbs surface area is a heatsink.
How do they manage to get good efficiency, and make it a "green" product?
Thanks.
