Great Value for money! I am not sure if this are realy made for 100W or if this is more a 70W LED. (0.5W/Emmitter) Seems to be great for repairing broken "100W" LED Floodlights. (these most also don´t have 100W but only 70W) At 2.1A Vorward Voltage is approx. 31.5V (25°c) At higher temperature Vf drops down to approx. 30-30.5V. The greatest thing about these LEDs is the really good matching: Even at 50uA all Emmitters are lit. At 1uA some rows are not lit and some others are (only visible in Darkness) Great LEDs for a low Price. I don´t expect any one of them to fail. I would recommend these LEDs for example in Workshop Lights wich are not used every day. For Lights with daily use i would buy more Expenisve ones. This seems to be the cheapest LED with decent quality i have found so far. Don´t fool yourselfe and buy crappy LEDs for some cents less.
Fast delivery... Excellent.. Thank you..
