As the title says....avoid this cheapass company and their shitty products. I bought a few fc 6500 lights. Less than 18 months use and all of them have pretty much failed. By failed i mean the dimmers do not work, when you turn the lights up they dim themselves and you don't get the full output you paid for. Mars Hydro's response with their 5 year warranty..............re wire them yourself lmfao. I wish i just went with Lumatek or someone who actually made half decent products. This kind of attitude especially with high powered electrical equipment is outrageous. Avoid at all costs
