charteristics of an LED that is about to fry?
Hi,
I got a few LEDs via ebay cheap, so I knew that a 4.5 volt button battery was too much current, but wanted to try anyway. (the forward voltage is rated 3.3)
it didn't fry the LED in this case, but I didn't seem to get more light and the LED was heating up. so that is a clue that you're putting too much volts thru, since it runs almost without any heat within voltage.
Any other signs? I noticed that some LEDs also have a brighter MCD #, but you need to pulse it, not run continously.
