impexeris This with 50 LEDs is a 50W. I have bought 1pcs 100W and 1pcs 50W LED and the one with 100individual LEDs (100W) is good - when slowly raising the voltage all of the ligh-up at the same time and brightness increase uniformly. While that with 50 individual LEDs (50W) is out of specs as individual LEDs light up at different voltages and their brightness increase not uniformly.
