A light cover for protecting recessed lighting fixtures from exposure to fluid during painting or other ceiling treatments has a shield, sized to fit over a baffle and an outer trim of a recessed lighting fixture, and a mounting flange sized to fit within the baffle and frictionally engage the light cover to the baffle. The light cover has a handle located on the shield and the handle is used to engage the flange to the baffle to secure the light cover to the recessed lighting fixture prior to a ceiling treatment. The handle is also used to disengage the flange from the baffle to remove the light cover from the recessed lighting fixture after completion of a ceiling treatment.
