WOW! I wanted to get these lights for my 36 gallon but I dont get why you put the puks in the center and dint put a space between the 2! Also how is the 24 with two puks 90 watts and you thought and planned better with the 48 and put 6 puks but yet it says that one is 180 watts which is double but triple the lights. Also , do you have a branch in usa or would I have to send to China for repairs ect? I know a lot of usa store carry your products but I saw you on ali express and all Chinese companys! Thanks. Can ya send me a discount code? LOL
