Review on 🔴 High-Quality eBoot Assorted Emitting Diodes for All Your Electronic Projects by Flavio Iyer

I used these as directed 20 mA in a microscope illumination. I noticed that after a while the illuminator wasn't as bright as I thought it would be, but maybe it's just my memory. I used two power supplies to power a 10mA LED and a 20mA LED. After only 5 days of continuous lighting, the 20mA LED was significantly less bright than the 10mA LED. I suppose I should repeat this test at 5mA, but the bottom line is if you want them to last long don't run them at 20mA. Keep it at 10 milliamps or less.
