What company did you buy it from? Did you get the 6500K bulbs? The reviews I have read are not very good, at least from the seller I was looking at.
No problems with Aquatrader? The reviews I have read on them are terrible. Broken bulbs, fixtures that spark, and melt, an almost no customer service. I was all set to order from them, until I started researching them. Did you have to communicate with them at all? If so were they helpful?
