HenningSWrote 3123 days ago.Uses a 3x3 Chip Matrix inside (see pic#2). Great - it is _very_ bright at 12V! Requires an additional heatsink urgently (the alu ground plate is not enough!). My 1st one overheated w/o heat sink and died after 2 minutes, just during taking the fotos...
By foksa11/01/2018I was skeptical at first considering how cheap this light are, but they are great. Light is really bright. They do generate a decent amount of heat when running at full power but that is normal for this kind of LEDs. To use them to their full potential you will need a current limiting driver ( http://bit.ly/2vV29RT ) and a decent heatsink: http://bit.ly/2vUJPs7
