That eco 98 by Mars is surprising it is close like 12 inches away man it is making huge bud. I'm very impressed with the so called beginners light they put s piece of plastic over the chips but keep it off there new Mars 2 series they want 100 dollars more for the veg and bloom Mars 2 400 same coverage I doubt it is. IAM taking the plastic cover off asap. I love trying different lights it is very addicting lol is Mars using the same chips in this build as they use on the Quantum board? It is the smd chip I'm not sure but I think they are. Those popular grow cobs cree imitation hold there own static driven at 600 ma cheaper lights but work. That is what I used to grow these plant. Cheap as chips leds
