Lenses disperse light to reduce glare and protect bulbs from damage. Cut to size using a band saw or shears.

Solid lenses keep bulbs hidden and distribute light evenly. Lenses with a prismatic or cracked ice pattern distribute light better than smooth lenses. Smooth lenses for LED lights scatter the directed light of an LED better than other solid lenses.

Egg crate and parabolic lenses have an open construction to allow more light through than solid lenses as well as more air circulation to cool bulbs. Parabolic lenses are reflective to direct light downward, which reduces glare.

Polystyrene lenses are the most economical, but they may yellow over time. Acrylic lenses won't turn yellow over time. Polycarbonate lenses are more impact-resistant than acrylic lenses, but they may yellow over time. Aluminum lenses withstand higher temperatures than plastic lenses.

Also known as troffers, these lights fit most standard drop-ceiling grids, so they’re often used in indoor spaces such as offices and storage rooms. They can be hardwired to operate on any of the voltages listed.

Lights with a solid lens are frosted and smooth or prismatic to disperse light evenly. With built-in LEDs, these lights last longer, are more efficient, and generate less heat than fluorescent lights. They emit a neutral white light often found in workspaces.

Lights with a parabolic lens are reflective to direct light downward and reduce glare. They require fluorescent bulbs (sold separately).
