Lithonia Lighting 4-Foot Diffuser Lens for SB Series Narrow Body Wraparound – 48 in

Refresh your SB Series 4-foot wraparound with a replacement diffuser lens

Restore even, comfortable lighting to your workspace with Lithonia Lighting’s 4-foot diffuser lens. The clear prismatic acrylic is engineered to balance brightness and glare, helping your existing fixture deliver consistent illumination without changing the setup you rely on.

The diffuser’s optical design blends practicality with a clean, unobtrusive look. Linear side prisms help spread light evenly across the space, while pyramidal bottom prisms minimize lamp image for a flatter, more uniform appearance when viewed from below.

Key specifications

• Dimensions: 48 in L x 8-5/8 in W x 2-5/8 in H, designed for the SB narrow body square profile 4' housing.
• Material: Rigid acrylic that resists everyday wear and supports the diffuser for easier maintenance.
• Location rating: Damp location compatibility makes it suitable for garages, workshops, and utility rooms.

Durability, maintenance, and installation

• Continuous diffuser support helps prevent accidental openings and simplifies upkeep between cleanings.
• Lens only — hardware and the light fixture are not included, so you can refresh an existing setup without replacing the entire unit.
• 1-year limited warranty offers peace of mind along with verified measurements and model compatibility before ordering.

Practical uses and benefits

• Closets, garages, and shop areas can benefit from more uniform illumination and reduced glare.
• The design supports a clean ceiling line while maintaining brightness for everyday tasks, repairs, and organization.

If you’re looking to upgrade without a full fixture replacement, this replacement diffuser lens provides a practical option that aligns with existing SB Series 4-foot wraparound lights.
