This attractive fixture is coated black with a hard, scratch resistant material for durability and is rated at 200 watts to support the large heat emitting devices our cages require (most fixtures sold in pet stores or in catalogs are only rated 75 watts and the finish is not nearly as durable). Set on top of cage with wire top, wire top inserts, perforated aluminum inserts, or mount inside cage with mounting hardware. Guards sold separately. Guard shown is 1/2” wire guard for dome fixture.
