This is an RGB 5mm LED, 4 legs, common CATHODE (negative), misted/diffuse shell. Sold in a pack of 10.
Very bright* (high luminous intensity) to my uncalibrated mark-one-eyeball.
Rough specs as provided from the manufacturer…
Red: 1500 MCD, Forward Voltage 1.9V
Green: 5000 MCD, Forward Voltage 3.3V
Blue: 3000 MCD, Forward Voltage 3.3V
I don’t have a maximum recommended current, but I would shoot for about 20 mA maximum (most LEDs are happy around that).
Remember to use a current limiting resistor, no resistor = instantly destroyed LED in most cases.
I have a few different types of LED listed, check out the others here: 283.mytrademe.info
The best and really only way to see if a specific LED (or indeed batch of LEDs) is bright enough for YOUR purpose, is to buy a few and try it out. Luckily, LEDs are just a few cents!
