I have one. The bulbs that come with it are junk! So they should be replaced right out of the box. By the time you put even decent bulbs it it you are looking at the same price or more than just buying one that has good bulbs in it already and maybe moon lights or some other nece features built in. I'm selling mine to my brother and getting the coralife lunar fixture for less than I payed for that fixture and new bulbs. But the lunar comes with moon lights already on it and better bulbs too. Hope this helped
