Vapor Tight LED Lighting, NSF, IP66 to IP69K for Wet Locations

Built for wet, washdown, and corrosive facilities, our vapor tight LED fixtures seal out water, chemicals, and dust for reliable light in food plants, car washes, wastewater rooms, and harsh industrial bays. IP66 to IP69K enclosures with NEMA 4X hardware and NSF listings support sanitation, daily hose down, and compliance. Choose linear or high bay formats with scalable lumen packages to match ceiling heights and tasks. Tight gaskets, impact rated lenses, and rugged mounts keep light levels stable while reducing maintenance and downtime across wet production lines and service areas.

When to Choose Vapor Tight LED Lighting for Wet Locations

Use vapor tight LED lighting when wet, washdown, or corrosive conditions demand sealed fixtures that keep performing. These luminaires pair NSF options with IP66 to IP69K and NEMA 4X construction for sanitation and durability.

  • High pressure spray, foam, steam, and hose down routines in food plants.

  • Constant moisture in car wash tunnels and bays, with chemicals present.

  • Wastewater headworks and clarifier decks, splash zones and chemical rooms.

  • Cold storage and cooler aisles where condensation and frost are common.

  • Low to mid heights, 8 to 16 ft, pick linear wide or diffused optics.

  • High bays, 18 to 35 ft, use aisle or narrow distributions to reach the floor.

  • Areas with salt, detergents, or acids where corrosion resistant hardware is critical.

  • Sites needing controls, 0 to 10 V dimming, occupancy and daylight sensors.

Vapor Tight Lighting Certifications and Compliance, IP66 to IP69K, NEMA 4X, NSF

Vapor tight fixtures must be verified to operate safely and consistently under water, spray, and corrosive exposure. The families on this page carry the core ratings and performance metrics buyers expect for wet and washdown environments.

Key ratings and compliance items include:

  • Ingress protection, IP65 to IP67 on linear and high bay models, IP69K where specified, seals out water, dust, and high pressure spray

  • NEMA 4X housings with corrosion resistant materials and stainless hardware for washdown and coastal areas

  • UL wet location listings and NSF components or certification, suitable for food production zones where required

  • Impact protection such as IK10 where available, durable lenses for busy bays and tunnels

  • DLC or DLC Premium qualification where offered, supports rebate eligibility and efficiency targets

  • Universal input, typically 100 to 277 V, high voltage options on select models, 0 to 10 V dimming ready for controls

  • Rated life and lumen maintenance, L70 or L90 figures documented per family

  • Ambient temperature ranges and gasket integrity validated for daily sanitation cycles

These ratings ensure sealed, code friendly operation, long service life, and predictable performance in wet, corrosive, and hygiene critical applications.

Vapor Tight Lighting FAQs

What is the difference between IP66 and IP69K?

IP66 seals against dust and powerful water jets from any direction, good for wet locations and hose down. IP69K adds very high pressure, high temperature spray resistance, ideal for direct washdown in food plants and car wash tunnels.

What does NSF mean for lighting in food facilities?

NSF compliance confirms materials and construction meet sanitation requirements. Fixtures are smooth, non toxic, and easy to clean, and are suitable for use in inspected food zones as specified. Choose NSF where audits or HACCP plans apply.

How do I choose mounting heights and distributions?

Use linear vapor tights at 8 to 16 ft for wide, uniform coverage. Use vapor tight high bays at 18 to 35 ft with wide or aisle optics to push light to the floor. Typical spacing is around 1.0 to 1.2 times mounting height.

Do these fixtures support dimming and controls?

Yes, most models include 0 to 10 V dimming. Add occupancy or daylight sensors and network controls to cut energy, maintain light levels during sanitation, and meet code, using sealed accessories suited to wet areas.

Are vapor tight LEDs resistant to car wash chemicals?

Specify NEMA 4X housings, corrosion resistant hardware, and impact rated lenses. For foam and high alkalinity or acid detergents with close range spray, select IP69K models. Rinse residues and inspect gaskets on a regular schedule.

How do vapor tight LEDs perform in cold storage?

LEDs start instantly in low temperatures and sealed housings help control condensation. Verify the ambient rating on the model you select, many operate well in cooler and freezer applications with optional emergency packages available.
