The 4FT-Vapor Tight LED Vapour-Tight Light is a versatile commercial and light-industrial fixture designed for locations that require protected, dependable illumination and automatic lighting control.

Its enclosed 4-foot linear housing helps protect the internal LED components from dust, moisture, and demanding indoor conditions when installed according to the manufacturer’s requirements. It is well suited for parking garages, warehouses, workshops, utility rooms, storage areas, service corridors, and compatible low-bay applications.

Five selectable wattage settings—25W, 30W, 35W, 40W, and 50W—allow the installer to adjust the fixture’s power and light output based on the room size, ceiling height, and required brightness. This flexibility helps reduce the need to stock multiple fixed-wattage fixtures.

The fixture also includes five selectable colour temperatures:

• 3500K for softer white illumination
• 4000K for balanced neutral white light
• 5000K for daylight white illumination
• 5700K for a cooler daylight appearance
• 6500K for crisp, high-visibility lighting

Its wide 120–347VAC input range supports many commercial electrical systems. A built-in 12V DC supply and integrated sensor provide automatic lighting control, helping reduce unnecessary energy use in areas that are not continuously occupied.

Always confirm the sensor functions and settings, environmental rating, mounting requirements, control compatibility, operating temperature, certifications, installation instructions, and local electrical code before installation.
