SONLIPO SPC3500 LED Grow Light 350W, 4x4 ft Coverage with 1464 Samsung LEDs Sunlike Full Spectrum with UV & IR, Dimmable Daisy Chain Timer VEG & Bloom Grow Lamp Hydroponic Indoor Plants Seeding Flower

These are good lights but they have one major issue. I purchased two of these and both of them had the same problem, the on/off switch gets hot. They melted the terminal connection insulation and the switch had internal failure. When I contacted the company they recommended jumping the switch out like I did in the last two pictures. This means they know they have an issue but they won't send new switches or exchange the light, you have to do it through AMAZON. The other concerning issue is this could be a fire hazard. I really can't recommend buying these light for long term usage.

What a difference from what I had. verry happy with the purchase. Would buy again but hope I don't have too.

Beautiful bright full spectrum light. 10/10 for light output.I hope that their future products make improvements to the electronics.A $300 product should not cheap out as much as this thing does.The six light bars are wired in parallel. Each bar has three charlieplexed LED banks.There's no UL sticker on this thing and there's no way it could get one. Too many short circuit hazards, and generates too much interference.The control electronics are amateurish, especially the board-to-board connections. Undergrad science project level engineering. The control board in my unit died after 6 months, but Sonlipo fast shipped me a new one to install. The replacement board had some different connectors and wire colors, but after putting the right connectors on it the replacement part did work.The DC supplies (it has 3) are potted, which makes no sense since this unit is not water resistant.They get very hot, and generate a TON of RF noise.I had to add shielding because the RF noise was coming through my headphones and causing my computer screen to glitch out.

I got 2 on sale before Christmas to replace 2 of their older spc2500 models and my plants absolutely love them. The light bars aren’t rotational like they are on other models but they make up for it by closing the gap between light panels giving a more even canopy coverage. They don’t put off crazy amounts of heat and seem very well built.

Specs shown are close, networking together is good too.
