Lumatek DOES NOT honor their warranty.....they have ZERO employees in the USA....they are in england....they have a US distributor....the distributor actually answers the phone (lumatek does not).....the distributor says they only ship the products....the guy told me he has NEVER seen any returns get shipped back to lumatek....the distributor does not represent lumatek...lumatek only has SALESMEN in the US....the salesmen have nothing to do with warranties....they only sell...if you have a warranty problem, the salesmen either can't (my guess), or won't honor the warranty....its your problem, not lumateks....i can show you the unreplied emails to lumatek...i believe that because its hydroponic stuff, they know you won't make a stink, that you'll just eat it and they can hide across the pond....its pretty simple folks....when you buy a lumatek product, YOU DO NOT HAVE A WARRANTY....the hydro stores push lumatek because it is their highest profit ballast, not because its the best....the products suck, and the company that makes them hides in the UK....I strongly reccommend you stay away from lumatek trash....if you want to see the unreplied emails, drop me a line and i'll send em to you
