Vapor Proof Lenses

Replacement Vapor-Proof Lenses for Industrial Fixtures

Our vapor-proof lenses are sealed replacement covers for industrial light fixtures used in damp, dusty, and corrosive environments. These include food processing plants, parking garages, car washes, loading docks, and any space where moisture or airborne particles would damage a standard open fixture. We carry multiple sizes and profiles to match common vapor-tight fixture housings from major manufacturers.

Each lens is made from impact-resistant polycarbonate or acrylic, depending on the model. The gasket seal keeps moisture, dust, and chemical vapors away from the bulb and wiring. If your current lens is cracked, yellowed, or fogged, replacing it restores full light output and maintains the fixture's IP rating.

How to Find the Right Replacement Lens

Vapor-proof lenses are sized by length, width, and depth to match specific fixture bodies. Measure your existing lens or check the fixture model number before ordering. Our product codes (like ALP-TDW4DD15 or ALP-4ARD15) include the dimensions in the name, which makes matching easier. If you can't identify your fixture, send us the measurements or a photo and we'll help you find the right fit. For other types of replacement covers, browse our replacement lenses collection or our light covers and diffusers. If you need the full fixture rather than just the lens, check our LED fixtures page.
