LED : the led chip can not directly connect 220/110V . must work with a transformer. and considering the feature of the high power led,we advise constant current drive to maintain the quality and long life-spon.

LED driver : should be high quality constant current led driver. make the led work.

Heatsink : like this high power cob led chip, the heat is very focused . so the heat must be transfer to another object . without the heatsink , the led would soon burned in couple of minutes.

Cooler : Unless the heatsink you use is big enough or super material to maintain the heat goes . normally , we advise a fan work with fan driver. on the back of the heatsink, in this way , the temperature would not too high to keep up the led working smoothly.

Lens,reflector : lighting beam angle is important in modern growing. especially for cob led . now we provide 60 90 120 degree glass lens .
