Acuity Lithonia SB Series Replacement Lens 48 in Acrylic

48-Inch Acrylic Replacement Lens for SB Series

This 48-inch acrylic lens is a direct replacement for Lithonia Lighting SB series fixtures. It measures 48 inches long and 8 inches wide with a smooth pattern and white finish. The lens restores original light distribution in commercial or residential installations. It is cULus listed for safety compliance.

Sustained Light Output and Material Stability

The acrylic construction maintains consistent light transmission over extended operating periods without yellowing or brittleness. Its smooth pattern ensures even diffusion across the 48-inch length during continuous use. The unfinished surface resists dust buildup that can degrade output over time. The cULus listing confirms the material meets safety standards for prolonged operation.

Replaces Damaged or Aged SB Series Diffusers

This lens replaces cracked, yellowed or missing diffusers on existing SB series narrow-body fixtures. The upgrade is worth it when the original lens no longer provides uniform illumination or has become a safety hazard. It fits 4-foot SB narrow body housings without modification. Buyers needing a different length, width or lens pattern for non-SB fixtures cannot use this part.
