The GLT LHB-60L (347–480V) is a very-high-output contractor-grade LED linear high bay engineered for the largest commercial and industrial facilities running high-voltage distribution systems. Four selectable wattage steps (164W / 246W / 328W / 410W — 40% / 60% / 80% / 100%) and dual selectable CCT (4000K / 5000K) are adjustable on-site via built-in switches before installation. Delivers up to 60,600 lumens at a peak efficacy of 171 lm/W on a 347–480V 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.

Performance & Light Output

Lumen output and efficacy are identical across 4000K and 5000K CCT settings. At 410W (100%): 60,600 lm / 148 lm/W. At 328W (80%): 50,000 lm / 152 lm/W. At 246W (60%): 38,400 lm / 156 lm/W. At 164W (40%): 28,000 lm / 171 lm/W. CRI 80+ maintained across all settings. Rated life 50,000 hours per IES LM-80 results and TM-21 projections (L70).

Smart & Control Features

The LHB-60L (347–480V) includes a standard 0–10V dimmable driver and supports plug-and-play sensor accessories for occupancy and daylight harvesting control:

• Plug-and-Play PIR Sensor (12–24VDC): MSANT12VPH01 (standard) | MSANT12VPHB01 (Bluetooth) — sold separately
• Plug-and-Play Microwave Sensor (12–24VDC): MSANT12VMH01 (standard) | MSANT12VMHB01 (Bluetooth) — sold separately

Main stocking sensor SKU: MSANT12VPH01. Bluetooth variants enable wireless group control without a separate gateway for smaller installations.

Electrical

347–480V AC input, 50/60Hz. Standard 0–10V dimming driver. TAA compliant. Driver integrated within the aluminum housing for thermal protection and extended component life.

Construction

Die-cast and extruded aluminum housing for superior heat dissipation and structural rigidity. White powder-coat finish. Frosted polycarbonate lens for uniform light distribution. UL listed for damp locations. Dimensions: 36.22" × 11.02" × 1.65" (920 × 280 × 41.8mm).

Installation & Mounting

Steel wire rope suspension mount is included for chain/pendant installation. Surface mount and conduit pendant mount kits are available separately. Recommended ceiling height by wattage setting: 164W — 18–25 ft | 246W — 22–30 ft | 328W — 25–35 ft | 410W — 30–40 ft.

• Mounting Options: Steel wire rope (included), surface mount kit (sold separately), conduit pendant mount (sold separately)
• Emergency Battery: 30W 4000lm 90-min — suits 347–480V input voltage (sold separately)
• Sensors: MSANT12VPH01 (PIR), MSANT12VMH01 (Microwave), Bluetooth variants available — sold separately
• Wire Guards: Available separately

Certifications & Rebates

UL listed for damp locations. DLC Premium listed — eligible for utility rebate programs in most U.S. states and Canadian provinces. Verify eligibility at designlights.org. TAA compliant for federally funded projects. RoHS compliant.

Typical Applications

• Large Warehouses & Distribution Centers: 410W / 60,600 lm covers the widest bays and tallest racking; 347–480V input suits facilities with high-voltage distribution panels
• Manufacturing & Heavy Industrial Facilities: Damp-location rating and cold-start capability handle the most demanding production floor environments
• Large Retail & Big-Box Spaces: Dual CCT selection lets facility managers match existing ambient lighting across expansive floor plans
• Commercial Garages & Auto Service: Very high lumen output eliminates dark spots in large multi-bay service facilities
• Athletic & Arena Facilities: 410W / 60,600 lm handles the highest gymnasium, arena, and natatorium ceilings
• Cold-Storage & Refrigerated Warehouses: Cold-start rated to -40°C — powers on at full output in freezer environments
