Ordered 220v/50W/4200lm/Warm white 2pcs. Looks like it is 3200K as far as i can tell. Consumes 65Watts on 238Volts. Its very bright but gets very hot! Needs a cooler with at least 65W TDP. An old AMD cooler with a big enough base(min 5.5cm*3.5cm to cover the cob and the driver circuits) ran at full fan speed will keep it ideally below 80C with an ambient temperature of 30C. Needs lots of thermal paste! Its easy to solder just dont put it on the heatsink before soldering. I gave it 4/5 on quality because its not efficient but hey its cheaper than anything.

use heat sink with fan from computer for heat generate to hight 50 C if fan operate is temp. down to 30 C
