I would like to use brighter leds on my cmoy... like these? http://superbrightleds.com/leds.htm


any suggestions that will still be ok with a 9v batt? Or is it very hard to run off computer power? Like a 12v line?

I use leds from lsdiodes.com . For which ever led (including 3mm like blue/red) i just put a 10k resistor and the light is eye-hurting bright. This is off a 9v battery, you could use the same resistor with the 12v and will give a slightly brighter light. You can use a resistor as low as 400ohms or so to give the brightest light without burning the led up quick (i used these resistors when i put leds in all my car door/window/etc switches).

The brightness rating they give, in millicandelas, is at a current of 20mA. Ohm's Law says that V/I=R, or 9V/.02A=450Ohms. A fairly small (400-500) resistor will leave that 10K mcd LED bright enough to light your room

out of interest, has anyone found a decent source of t1/3mm pink and uv leds?

I don't know about pink, but lsdiodes.com has UV LEDs. Very bright ones. You might even want to talk to them about pink - if they don't carry it, they'll know where you can get it.

cheers. ill email them. i found one guy on ebay that sells them, but i don't have the need for enough to order from them. project studio pimeta may have to get pink and uv led's for the metering though

How many you need?

oh just a handful a couple of dozen...i was going to order some led's off the ebay guy anyway, may just see what package they can put together for me
