    Great Led, very bright ! Perfect cooling with a old P4 heatsink. I limit the current at 2.8A to have 100W on the led, NOT 3.5 A !

    i build a 1000W Monster Led Light with this Led Chips. But the cooling is a huge problem. You really should be careful and always check the temp. to have a long lifetime!

    It's a great product! All 100 individual led's light up nicely. The only thing that bothers me is that the advertised voltage (32-34 volt) is not correct... like Elipsoid says, the led needs 38 volts to work correctly. I orderd a boost module with it that only goes to 35.8 volts so i had to order an other one that will reach the 38 volts. That is a bit unfotunate.

    I ordered five of those and all work perfectly. However, you need a BIG heatsink and fan in order to drive them at full power. I use one 18x8x4cm Aluminium heatsink with 60mm fan for each LED and still had to limit them to 60W in order to keep them at an acceptable working temperature. For this I am driving them at 32,9V @1,9A. The difference in brightness to full power (36V, 3A) might be measurable but is not visible (at least not for me).
