Great price, very bright for about 5 minutes until I let the smoke out of them lol. My fault, I'm running 3w red led strip along the bottom of my nighthawk build and 2 of these mounted at the bottom front for headlights. I bought them a while back and finally decided to install them. They don't like 12v LOL, totally my fault. Probably buy some more and step down to 3v like stated.2.5 volts max as they get very hot on higher voltage. Much brighter than the strip LEDs of 12v.
Bought two, blew one up carelessly by putting it on the same circuit as my 12V strip lights, the other one is going strong. Maybe I got an especially good one, but this LED withstands 5V without issue (it does get hot to the touch, though).I put three in parallel and hooked them up to a 3S they put out an instense light, i am yet to run them long term but its on the project listDoes not come with connector. Fairly big for what I wanted. Probably would be ok with a different setup. Just not for me.indeed this is a light , very impractible being 3.6max voltsun beau petit phare d'attero pas trop grosUsing with 10 ohm resistor on 12v supply as headlight for my ebike. This LED puts out quite a bit of light! It's about the same as my motorcycle's low beam. I'm going to add a couple more later on for extra light. Note that you'll need a bigger heatsink to go above 1 1/2 watts. I pulled one off the northbridge chip on a dead motherboard and used thermal compound mixed with epoxy in a very thin layer to glue it on. Using my IR temp gun the LED is only a couple degrees above the heatsink after 5 minutes so the thermal conductivity is good.Very bright little light, have it hooked up to 2x 1.5v AA's. Great landing light or navigation light.Easy to use bright led, wires is about 10 cm long 1,5 cm connector. it gets warm from 3,3 volts but it not burn hands when you hold it.
