    Default Telling leds apart

    Is there anyway to tell a cree bbw apart from a cree ggw? Ordered both and they came unmarked as far as I can tell.

    Test them with a power supply and resistor(s) Make sure not to look directly at them.

    If you have a multimeter, on the diode setting it should put out enough current to just turn them on, so you can look at them without searing your eyeballs.

    I just use alligator clips with a coin battery. It's hard not to get beamed in the eye though.

    I use the PSU and just turn the star upside down or put a piece of paper over it. I think I saw one of Erv’s videos where he did that.
