I would like some opinions on the support of luminaires in suspended ceilings. 2008 NEC, 410.36 states; "Luminaires shall be securely fastened to the ceiling framing member by mechanical means such as bolts, screws, or rivets. Listed clips identified for use with the type of ceiling framing member(s) and luminaire(s) shall also be permitted. Are the bend out "clips" on the fixtures considered a "listed clip"? Would you have to see spec. sheets for each type of fixture to determine if they are "listed"? What do you think?
