how to take apart lighting?

[fei_chu]

I recently bought a coralife 36" hood. I tried to take it apart but it seems to have those screws that you cannot take off unless you break them. If anyone knows how to take this apart safely without breaking anything. please let me know. thank

My description of the hood: the hood houses 2x36" flour and 1x175w MH
It is black in color and 36" long with one fan at the end. has white reflection inside and a splash/uv guard. i hope someone will know what i am talking about. thanks again
