Hanging Light Fixtures?

[bljohnson]

Anyone have experience hanging lights on the ceiling? I want to hang a 5' ATI Powermodule but am not impressed with the hardware at Lowe's/Home Depot. The hooks look like they are rated anywhere from 30-50 pounds when used on drywall and 50-60 pounds when in a stud.

Another option is using this:
