Just gonna throw in a vote for Mars, seems no one likes them. I have the new fce4800 in my 4x4 and the smaller
fce3000 in my 3x3. I have gotten great results across 4 strains on my 1st run in the 4x4. Has has IR far red and UV. Movable bars so u can customize your light distribution. 2 side by side in a 4x8 would be good I think. Also I'm tough on customer service, as a waiter I expect a lot, I had an issue with not getting enough PAR info, they responded to my Amazon review in 12 hours with the info. Maybe they only responded cuz it was on Amazon, idk. Check out Dr. Mjcoco on YouTube, he does full reviews with par tests. The fce series light did very well, but you can search his archive for whatever light you want to see if he's reviewed it. Have fun on your shopping spree!
