I would like something that is full spectrum and good coverage. I would spend up to 500 if its really worth it. But really want to get a good light with good coverage. I know nothing about LEDs Thanks
This light right here would do very well in your 4x4. Check it out. Amazon.com: MARS HYDRO FC-E4800 LED Grow Light 4x4ft UV IR Full Spectrum Grow Light Bar with 2646pcs Diodes 480Watt Plant Growing Light Dimmable Commercial Grow Lamp Daisy Chain Detachable, Achieve 2.8 umol/J : Patio, Lawn & Garden
Ur best thing to do is jump on utube look up Migro he does real reviews for light companies with real data
No particular brands to recommend but I'd stay right around 480w actual draw for a 4x4. Plenty of light without heat issues. I know that people run 600w in a 4x4, I just have no idea how. If I keep my room at 67 degrees my tent stays at 78. My house stays chilly during flower.
