I have a board with a couple of blown 5mm LEDs on it I'd like to replace. Here are pics of the board:
The inner 3 LEDs are white and 2 of them are no good. The rest of the LEDs on the board are fine (they are red and yellow). I swapped all 3 of the white LEDs with some generic ones I got in a kit. I did all 3 so they would be the same colour, but they are too bright compared to the ones I replaced.
I'm looking for the best way to find a suitable replacement that won't be so bright. Measuring in diode mode on my multimeter the original LED reads 3.033, the replacement I tried to put in reads 2.587. I then tried to run them on my psu with a 20mA constant current. The original needed 3.612V and the replacement only needed 2.862V.
The problem is I don't know what to do with that information. I've never had to try to characterize an LED before. Looking at some specs on Digikey I have no idea how many millicandela, viewing, angle, wavelength, etc. Truthfully I don't need an EXACT replacement, just something within the ballpark that doesn't stand out. Any help is appreciated.
