Review on Brighten Up Your Project With Edgelec 12V Pre-Wired Red LED Lights - Pack Of 50 by Ron Damndjperiod

Nice and bright, consistent, and works actually way down to about 2V (at reduced brightness of course) and operates up to about 15V, where the forward current is still trimmed to less than 15mA by the onboard transistor. I have used these as indicator lights for a number of projects ranging from pathway lights used at night time events to low voltage indicators to using one as a signal source to run a current amplifier flashing bigger LED chains. So far they are consistent in their performance and cost way less than assembling them by hand with discrete T1-3/4s
