Vapor Tight Light Selection Guide

A vapor tight fixture is defined by its gasketed, sealed housing and its IP rating, which together keep water jets and airborne grime out. The three styles here cover most jobs: Linear Vapor Tight Lights for rows over aisles and bays, LED Tri-Proof Lights for the toughest wet and dusty runs, and Jelly Jar Lights for wall and ceiling spots at entries and stairwells. For the broader plant catalog, see Industrial Lighting.

Match the Fixture to the Environment

The IP rating and form factor decide the fit. Match the wetness and dust of the space to the style below.

Output, Color, and Controls

Size a vapor tight the same way as any linear fixture: by length and lumen package over the area. A 4 ft linear vapor tight around 40W and 5,000 lumens suits general aisle coverage, with 8 ft and higher output models for tall bays. 4000K and 5000K dominate; 0 to 10V dimming and sensor options let you dial standby levels in low traffic rooms.

Ratings, Mounting, and When to Step Up

Confirm the IP rating against the space: IP65 handles water jets, IP66 handles powerful jets and heavy dust. Mount by chain, cable, surface, or pendant depending on the run. Where the area is classified for flammable gas or dust, a vapor tight is not enough and the job needs Explosion Proof Lights instead.

Frequently Asked Questions About Vapor Tight Lights

It means the fixture housing is gasketed and sealed so moisture, dust, and vapor cannot reach the LEDs or driver. The sealing level is stated as an IP rating, such as IP65 or IP66.

Choose IP66 for areas cleaned with powerful water jets or heavy dust, such as car washes and food processing. IP65 is enough for general damp areas and splashing.

Tri-proof is a type of vapor tight fixture built to resist three things: water, dust, and corrosion, usually at IP66 and above. Standard vapor tight linear fixtures handle general wet and dusty areas, while tri-proof targets the harshest runs.

Yes, when the IP rating and mounting suit the exposure. Many vapor tight fixtures carry wet location listings for covered outdoor areas like parking structures and loading canopies.

Match the length to the run and the lumen target. A 4 ft fixture suits standard aisles, while 8 ft fixtures cover longer bays with fewer mounting points.

Most commercial vapor tight fixtures include 0 to 10V dimming, and many accept occupancy or daylight sensors to cut energy in low traffic areas.

Yes. Sealed vapor tight and tri-proof LED fixtures perform well in cold storage, where the sealing prevents condensation inside the fixture and LEDs start instantly in the cold.
