Nuvo Lighting LED Light Bar Retrofit Kit, 4-Bars 4', Silver

A 42-inch 4-light LED retrofit kit for replacing 4 x 32W T8 fluorescent fixtures in commercial and industrial spaces, finished in silver.

The Nuvo Lighting 65-1337 Retrofit Lightbar Kit is a versatile and efficient solution for upgrading existing fluorescent troffers, strips, wraps, and vapor tight fixtures. With selectable wattages from 30W to 50W and selectable CCT from 3000K to 6500K, you can customize the illumination at installation. The durable aluminum housing and frosted polycarbonate lens ensure even light distribution and long-lasting performance. Designed for damp locations, this kit is ideal for warehouses, garages, and commercial workshops.

Best for

• Commercial warehouses and storage areas needing bright, uniform overhead light
• Garages and workshops where damp-rated fixtures are required
• Retrofitting existing 4-foot fluorescent troffers or strip fixtures
• Spaces with 120V-277V electrical systems, including multi-voltage installations
• Areas requiring 0-10V dimming for adjustable light levels

Not ideal for

• Residential living rooms or bedrooms - this is a utility-grade commercial fixture
• Outdoor uncovered areas - damp location rated, not wet location
• Spaces with ceilings under 8 ft if you need the full 4 ft length unobstructed

How bright is it?

Selectable from 3750 to 6250 lumens depending on wattage setting. At 50W, 6250 lumens is equivalent to a 400W incandescent - very bright, suitable for task lighting in large spaces. At 30W, 3750 lumens is like a 250W incandescent, good for ambient lighting.

Light color and feel

Selectable CCT from 3000K (warm white) to 6500K (daylight). 3000K provides a warm, cozy glow similar to traditional incandescent. 4000K is neutral white, ideal for workspaces. 5000K-6500K is cool daylight, enhancing alertness. CRI 80+ ensures decent color rendering.

Sizing and fit

Each bar measures 41.73" long x 0.93" wide x 1.19" high. The kit includes four bars, designed to fit into standard 4-foot troffer or strip fixtures. Magnetic installation makes mounting quick and easy.
