KASTLITE carries direct-fit replacement lenses for Lithonia DLB and DSB series wraparound ceiling fixtures. These are the most common 4-foot wraparound fixtures found in offices, schools, retail stores, and residential utility rooms. When the original lens yellows, cracks, or breaks, our replacement drops right into the existing fixture frame without any tools or modifications.
DLB vs DSB: What Is the Difference
The DLB48 is a 2-lamp wraparound fixture, while the DSB48 is a slightly different profile from Lithonia's lineup. Both use prismatic acrylic lenses that diffuse light from fluorescent or LED tube lamps. Our replacement lenses match the original dimensions and prismatic pattern for each model. If you are not sure which one your fixture uses, measure the lens width and compare it to the specs on each product page.
All lenses are made from acrylic, which holds up better than polystyrene in terms of yellowing resistance and impact durability. They clean easily with a damp cloth and mild soap.
