30W/50W/70W High Power Full Spectrum LED Grow COB Light Chip for Plants Vegetable AC110V/AC220V
A part of the review has been auto-translated.
This thing is as bright as the sun, it's also as hot as the sun. You'll want a good heat sink and a fan. Wiring is easy, just solder some lamp cord to the pads on the module and attach a plug and plug it in.
It just doesn't say what the positive and negative is.
ottima costruzione! necessità di un buon dissipatore passivo o attivo.

Very good and quality product!
working
very good perfect
This is the 70W 110v COB light. I have not tried this one yet but this is a replacement under warranty. The reason only 3 stars for Quality is because only one of the two I purchased before worked. I hope this one will work OK. I will buy again, Banggood stands behind its products.
Everything OK
Fulfills my expectations.
