LITHONIA LIGHTING Surface Mount Light Fixture Accessories D2SB48 SB Series, 48inch Overall Lg Replacement Lens 48 L X 13-3/4 W 1pc

Lenses and reflectors distribute and direct light from a lighting fixture. They fit surface-mount fixtures of a compatible brand and model. Replacement lenses are plastic light covers for changing out cracked or yellowed lenses to restore the appearance of the fixture and the clarity of light. They mount to the fixture frame below the light bulbs. Replacement reflectors are metal sheets or frames with a reflective surface that redirects light from the sides and top of the bulb to cast it downward for increased light output. They mount within the fixture housing above the light bulbs.
