I have seen lots of laser projects with 2.5 volts used and even 9 volts...
For instance my 120mW green uses 2 AAA or about 3+ volts.
But what dictates this?
I had some red diodes from a nice lightscribe burner, threw 2.8 volts into them and bam, dead in 2 seconds, were pretty bright though while it lasted.
I know current killed it, but how do you know what voltage to use on any given diode?
I am assuming there are several types of diodes that require different voltages? but then again, how would you know by just looking at one?
Thanks all........
