Household LED Lightbulbs

"Yup. Still, I didn't mean to start ragging on you. I'm sorry if it sounded that way. "

No worry. I don't get 'bent' too easy.

I put the LED bulbs in the post light (3) on the back porch. My wife asked me to turn it on & I replied it IS on.

Apropos to this discussion, I just saw a video on CNet about a new light bulb called Luxim. These little bulbs about the size of a Tic-Tac are very efficient, and amazingly bright.

I just picked up some LED bulbs at WalMart for only $5 each. They are replacement bulbs for the outdoor lantern or indoor chandelier type. They only use 1.5W, while they claim to be equivalent to 40W in light output, though they appear dimmer to me (there is no lumens rating on the package). They are also much bluer than incandescent bulbs. Still for the price, they should pay for themselves very quickly in energy savings. The life rating of the LEDs is 30,000 hours.

I need full spectrum light to work by. LED is bandpassed light, and casts odd shadows. Flourescent flickers enough that its unsafe to use machine tools.

At work I have flourescent overhead lights, but halogen lights at the machines.

If you want energy effecient LED's look for the energy star rating.

BuyLighting.com is another good source for affordable LED bulbs. They also carry high-pressure sodium and metal halide lighting. The way the price of LEDs keeps dropping, they may very well soon replace many other lighting types. http://www.buylighting.com/LED-Light-Bulbs-s/347.htm

"LED is bandpassed light"

Actually they are monochromatic.

I don't mean to correct people too much, I just like using big words.

Scientifically, I do not think it is possible, as darkness is the lack of all light, and what our eyes perceive as light and color, is nothing more than refracted light.

That said, I think a black hole could be considered a "dark light".

I thought I saw a 'dark light' once. It ended up just being Bart driving by in his uber-ebony VX.

Piers Anthony used a dark light in one of his Xanth books (can't remember which one).
