This light has one flaw. On one end one allen key was stripped so in order to open it I had o hack saw the corner and break it.
The damage is on one end and if you hang the light backwards you cant even see it. It makes life easier to change BULBS with light hanging from ceiling. Not much damage is on the main light. I tried to cut it such that the end strip was damaged.
If you want you can order the part from coral vue or premium aquatics.
Also included will be pair of 400w radium BULBS with four months of use. Also a pair of 400w XM 20K with two months of use. And four T5 with about 5 months of use.
I bought is used but the previous seller used it for six months and I used it for six months.
