It deceiving in that little space bro, the reflectors send the light out at that angle, the bright spots are just the light bouncing off the wall, its not any brighter then at canopy level, look at the light on the back wall that is around 3 feet from the light, it doesnt fade at all as it gets closer to the floor. I am following the same rules with this light as my big panels, start the plants around 48 inches from the panels and let the plants grow up into the lights as they get used to the intensity, the plants are now maybe 34-36 inches from the panel, by the time the strech is done around day 21 of flower the plant will be around 18-22 inches from the panel. Theres a few growers here that question this tecnique but I think my results speak for themselves. On my holy grail run the lights were on movers at about 14 inches from the canopy, even on movers the lights were way to close, the pistils were burnt at the tips and curled away from the lights, the nugs were also alot smaller than they should of been. A healthy plant has pistils that stick pretty much straight up, if your lights are to close they will curl downwards away from the intense light, its a good thing to watch for when you grow with led's. Now I dont know if the Helios diodes in my are 51 lights are better than epistar or not, the epistar definetly look brighter but brighter doesnt nessesarily mean better either.
