How to evaluate unknown specs of LEDs?

Parts Questions

Hello

Is there a way to find out about the electrical specifications of LEDs? Voltage, Max. Current, Recerse Voltage…

Thanks and Greets

Hi Roger,

uuuh, if you don’t have proper measurement equipment, forget it. Too much time to spend for number details. Why do you ask this question? Is Switzerland flooded with some huge unknown LED shipments?  ;D  LEDs are so cheap, it doesn’t make sense to spend time for “reverse-engineering datasheets”. A fast way to get at least some rough idea is try-&-error. Take a power supply, a poti and a multimeter and look for the voltage and adjusted current for a reasonable brightness. That’s it.

Cheers,

Thanks Skunk

I have 700 LEDs lying around without datasheet… I think I’ll try your tip.
