LED Voltages?

ras2a:

Im gonna be backlighting my trackball with some super-bright LEDs.  Just wondering what the best way to do this is?  I can't seem to find any 12v LEDs in the CPC catalogue I have.  Most have a max forward current of 4v.  Would I be ok with these connected to the 5v of a Molex connector, or do I need another solution?

Has anyone designed a rudimentary circuit for driving LEDs including resistors to limit the current?

I'm in the UK so can our UK brethren recommend a good source for appropriate LEDs?

cheers guys

well,not in uk but this is what i did...no need for circuits...run on 12v straight from power supply

ras2a:

cracking - nice one whammoed.  I'll check those out...wonder if there is something similar on offer here in the UK so I don't have to wait as long for shipping?

I'll have a look around

thanks again mate



whammoed:

no problem,
i know other people have used an led cluster that already has the molex on it to hook up to the power supply.  don't remember where they got it but a search here might come up with it.

this is where kevin at retroblast got his...they are called lazer led's
