What this fixture is and who it suits

The Acuity Lithonia SBL4 is a 4 ft LED wraparound fixture with integrated LEDs delivering 3,994 lm at 4000 K. It operates at 32 W and achieves 124.7 lm/W efficiency. The steel housing is finished in white and mounts on surfaces or suspended. It replaces a two-lamp T8 fluorescent and includes the LED light source.

Check your existing setup before ordering

Verify the supply voltage matches the fixture rating and that the circuit can handle 32 W per unit. Confirm the mounting surface can support 9.27 weight units and allows surface or suspended installation. Ensure your dimmer is compatible with integrated LED loads if dimming is required. The fixture is not linkable, so plan each run independently.

Behaviour under sustained load

At the rated 32 W the fixture maintains 124.7 lm/W efficacy during continuous operation. The integrated LED design eliminates lamp replacements over the service life. The steel body aids thermal management during extended use. No sensor is fitted, so output remains constant unless externally dimmed.
