DIY LED Lens for AC LED COB DOB Lamps Include: PC Lens+Reflector+Silicone Ring Lamp Cover Shades for LED Grow Light/FloodLight

This is my 2nd order of the led modules. Always buy more than you need because some of the the module's driver chips fail and the whole module needs to be replaced. When the modules work they are great.

So I needed a boost for my plants. They outgrew the coverage of the last light I diyed.I purchased two brands of basically the same chip. These are far more superior with wireless terminals. Which help, and give mobility if placement becomes an issue. Both of these chips w performed flawlessly. Only half of the four worked of the other type. I mounted them on an aluminum beer sign. And attached heat sinks to the back with the sms screws I used. My 6” duct fan blows on the back of the sign. Have it cycling with my fan. So it always has cool air flow. They do have a chip that cuts back the wattage if they aren’t at the proper temp. The total cost for me is under 50. I don’t have fancy equipment for par ratings. I know I’ve thrown all kinds of light at my plants and really didn’t expect the growth rates I’ve seen. ( in 24 hrs. )

I bought the 3500k 50w . But what I got was 6000k also a good product but ....its not what I wanted and not going to work for my project. FAIL

I’ve built 2 grow light from these cobs now. They are easy to work with are brilliant. All I did is use some thermal glue and a computer heat sink and ones has ran for 3 weeks and still going strong. My plants are loving them also. Nice and bright without getting too hot!!

This thing is bright. Will be building a indoor grow light this weekend with it. Totally worth it!!!

The boards are good quality and the quick connect is a godsend, but they are not 50w each as the title would lead you to believe, they run at about 20w from the wall.

Very bright blue light but makes everything thing fluoresce

The product shipped to me is not the advertised product. Specifically, the posted product was rated at 50 watts for 2 units each that I purchased. Amazon's vendor shipped me a similar product that was rated at 30 watts. This does not satisfy my needs. Please refund me the cost of my purchase and instruct me on how to return the non-preforming product. (Review does not allow for 0 star rating)
