BEHOLD!

good info though samhill wrote:I know what your talking about there Freetown, I went far too long burning my candle from both ends. Don't know if I'll be around to see that many more bulbs burn out, I'll most likely be leaving some perfectly good bulbs behind.

New LED bulbs are currently under development that promise to make them a good value and what you will want to buy. It's not there yet but it coming. A lot of new initiative ideas. For example, a metal bulb. I've posted before about the heat problem with LED bulbs. The chip, the source of light gets very hot. It needs a heat sink. Mounting it directly to a metal heat sink solves that problem. Make the metal in the shape of a glass incandescent bulb, and have lots of LED's all over it, in exactly the right places to get uniform light distribution would be ideal. But, the electronics would be a nightmare. Getting low voltage DC for each of the LEDs from 120 VAC is tough. But what if you put them all in series and powered them directly from AC. As the 60 Hz sine wave voltage rises only a few LED's would be illuminated progressing to all illuminated at peak voltage. This all happens at a 60 Hz rate, much like a TV raster. It's being tested in R&D labs now and some version of will become a real product the a few years. I will be expensive at first, but because of it's long life and superior light output, color spectrum, etc. it's what you will buy. Market volume will drive the price down.
