Ideal for surface or suspended mounting

The Acuity Lithonia LBL4 LP835 is a 4 ft LED wraparound fixture with integrated LEDs delivering 4188 lm at 3500K. It replaces two T8 lamps and operates at a maximum of 32 W with an efficacy of 130.8 lm/W. The beveled square lens provides broad illumination for commercial or residential interiors.

Thermals noise and power draw

At 32 W the fixture runs cool and silent with no moving parts. The integrated LED design eliminates bulb replacement and maintains consistent output over its rated life. Dimmable operation allows further power reduction when full brightness is not required.

Integrated LED and dimming change maintenance

No separate lamps are needed because the LEDs are built in, removing the recurring cost and labour of bulb changes. The dimmable driver works with compatible controls to adjust light levels for different tasks or energy-saving schedules. Linkable is not supported so each unit wires independently.

Questions about this item

How do I surface-mount the 4 ft LED wraparound and what step is often missed?

Secure the fixture to the ceiling with the supplied brackets, connect line voltage to the internal driver, then snap the beveled square lens in place; the step often missed is seating the lens fully so the gasket seals.

What part will need replacement first on the 4188 lm integrated LED wraparound?

The integrated LED array and driver are built into the 4 ft housing; when lumen output drops below useful levels the entire 32 W fixture is replaced rather than a single component.

At what point does the 3500 K wraparound hit its thermal limit during continuous operation?

The 32 W driver regulates current to maintain 130.8 lm/W; sustained operation at rated wattage is the design limit before thermal protection reduces output.
