reflective

hi i got hold of a few of these could any1 tell me if they would any good for reflecting light pls....

spray paint em white and theyll be great.

White reflects light. Black absorbs it.

flat white paint is about the best thing to use and cheapest.

i think they would create hot spots in the room.

if that's stainless steel sheet, sell it cause it's worth good $$$ then buy some panda film...
