For a few years now I've been lighting our bedroom mainly with white
Christmas lights strung across the ceiling. They've gotten pretty dim
and burned out by now, and need replacing. But they seem to heat the
room up quite a bit in summer, plus I'm getting somewhat bored with
them, so I'd like to try something a little different.
Red, green, and blue light is supposed to stimulate the red, green, and
blue cones in the eye to give the sensation of white in combination, so
I thought it might be nice to use strings of those colors, rather than
white strings. I think it'd be interesting to see colored lights when
you look up at the ceiling, but essentially white down below, where the
light is better mixed. But it seems like a bad idea to use
conventional incandescent lighting for that, since each bulb produces a
full spectrum of light which is then selectively filtered by the bulb
color coating, resulting in dimmer light, warmer room, more
electricity, sadder polar bears, etc.
It's my understanding, however, that LED Christmas lights are very
efficient, more so since the colored ones only give out narrow-spectrum
light. So I think I'd like to use them. But I have no idea about the
relative intensities of the R, G, and B that LEDs give of, and thus how
well they'll "fool" the cones. (And I see people complaining that
"white" LEDs often seem more blue than white.) Yeah, I know, I could
just buy three strings and check it out for myself, but before doing
that I thought I'd ask whether anyone else has tried this before, or
has any ideas on the subject. In particular, is there any way to get
output specs for the strings, and use that somehow?
Also, does anyone know how many LED lights one can safely attach to an
outlet?
And on a semi-related concept, after reading about how LED computer
monitors work, the question occurs to me: would it be better for screen
longevity and power consumption to use a desktop background that's all
white, or all black? Or doesn't it make any difference?
