About this item
About this item
- Four-Step Selectable Wattage — One SKU, Right-Sized Output: Switch between 52W, 78W, 104W, and 130W in the field — delivering 8,200 to 18,500 lm — replacing 175W–320W metal halide fixtures and eliminating the need to stock multiple SKUs for different ceiling heights.
- Dual Selectable CCT for On-Site Flexibility: Choose 4000K neutral white or 5000K daylight before installation — both options deliver CRI 80+ and identical lumen output for consistent commercial-grade illumination.
- UL Damp Location Listed — Built for Industrial Conditions: Rated for damp locations and cold-start performance to -40°C, making this fixture suitable for refrigerated warehouses, manufacturing floors, and condensation-prone environments.
- DLC Premium Listed — Utility Rebate Eligible: Qualifies for utility rebate programs through designlights.org, reducing net project cost for commercial and industrial retrofits.
- Plug-and-Play Sensor Ready with 0–10V Dimming: Compatible with MSANT12VPH01 PIR and MSANT12VMH01 microwave sensors (including Bluetooth variants) for occupancy and daylight harvesting control — supporting ASHRAE 90.1 and Title 24 energy code compliance.

Description
Description
The GLT LHB-18L is a compact, contractor-grade LED linear high bay designed for lower-ceiling commercial and industrial spaces where efficiency and field flexibility are essential. Four selectable wattage steps (52W / 78W / 104W / 130W — 40% / 60% / 80% / 100%) and dual selectable CCT (4000K / 5000K) are adjustable on-site via built-in switches before installation. Delivers up to 18,500 lumens at a peak efficacy of 158 lm/W on a universal 120–277V platform. CRI 80+, UL listed for damp locations, and DLC Premium listed for utility rebate eligibility. Cold-start rated to -40°C. 0–10V dimmable driver standard. Backed by a 5-year manufacturer warranty.
