I've had these lights for two years… I've had these lights for two years now. I have two 4x4 tents with 5 groplanner 150 o series lights in each of them . I grow 4 plants in each and my average weight is 8 ounces per plant. My biggest plant came in at 14 ounces that was an indigo express strain. I've compared these to spider farmer and they can't match the par value of the groplanner. Depending on whom you buy the lights from you can get them at a good price. I don't use the wifi since I don't trust wifi so I use digital timers. Groplanner recommends 4 lights but like I said use 5. One in each corner and one in the center. Excellent light penatration. I highly recommend these lights

Nice light for the cost Nice light for the cost. Very bright and user friendly. I like the controls being in my phone I can set a timer easily for the light.

O series 150 watt dimmable panel This is one very well constructed light. Even the carbines and connection cables and mounting hardware is made of high quality materials. Excellent lighting system that you can add on too as needed.

Just received my new GROPLANNER 150… Just received my new GROPLANNER 150 WiFi and waiting to see the results.
