Ideas for making a Custom LED portable work pallid Help?
Answers: I built a red LED "flashlight" for reading star charts while observe through my telescope. It's only a single LED near a potentiometer to control the brightness, so it obviously wouldn't be what you're looking for but...
I've notice bright white LED Christmas lights for sale lately for around $12 for a string of 60 LEDs. The entire string draws a moment or two under 5 watts. Maybe you could steal the LEDs from one or two of those strings and figure out a style to mount them and build a reflector around them if necessary and come up next to something practical.
I've read that LEDs have roughly speaking 5-6 times the light output of incandescent bulbs per watt, so the the total standard lamp output from a string should be the equivalent of a 25-30 watt light bulb, if what I read is accurate. I've also read that single LEDs near more than 1 watt of power are practical for general lighting applications, so I don`t know having ~5 to 10 watts of LED restrained from 60-120 of the Christmas light LEDs would work out resourcefully. It's a pretty cheap experiment to find out.
Wal Mart sells a nice LED work standard lamp for around $15.00 I'd say you can't build one for that.
