LED High Bay Warehouse Lighting

A 400W metal halide draws approximately 458W including ballast. Jarvis Lighting's HBL-A linear or A51-A-G2 UFO high bay at 150–200W provides comparable lumen output (20,000–30,000 lumens) at 56–67% less energy. The specific wattage depends on mounting height and target foot-candle level — use 150W for 20–25 foot ceilings and 200W for 25–35 foot ceilings.

A 4-lamp T5HO (~234W system) is replaced by the Jarvis HBL-A at 90–100W (57–62% reduction). A 6-lamp T5HO (~351W) by the HBL-A at 150–200W (43–57% reduction). A 250W metal halide (~295W system) by the A51-A-G2 UFO at 96–100W (66% reduction). A 1000W metal halide (~1,100W system) by the HBL-A at 250–304W (72–77% reduction). System wattages include ballast draw; LED wattages are at the driver with no additional ballast loss.

Below 30 feet, both form factors perform comparably and the choice is primarily aesthetic. Above 30 feet, linear high bays (Jarvis HBL-A Series) outperform UFO fixtures in aisle-oriented layouts because their elongated optical geometry produces a more controlled directional throw with less spill light between aisles. UFO high bays (Jarvis A51-A-G2 Series) are better for open floor plans where uniform radial distribution matters more than directional coverage. For 277-480V industrial circuits, the HBL-A offers a dedicated high-voltage driver option; the A51-A-G2 operates on 100-277V only.

Yes. All Jarvis LED high bay fixtures are DLC-qualified under DesignLights Consortium V5.1 standards, with 18 active DLC listings across the HBL-A and A51-A-G2 product lines. DLC qualification is the primary requirement for utility rebate programs covering approximately 80% of U.S. commercial electricity accounts. Typical rebates range from $50 to $150 per fixture depending on wattage and utility program. DLC Premium-qualified fixtures may qualify for higher incentive tiers. Jarvis provides DLC product IDs, specification sheets, and IES files for rebate applications.

General warehouse lighting at 30 foot-candles typically requires one 150W LED high bay per 800–1,200 square feet at 25-foot mounting height. Task-intensive areas like assembly lines require 50+ foot-candles, reducing coverage to 400–600 square feet per fixture. Jarvis Lighting offers free photometric layouts that calculate exact fixture quantities and spacing for your specific floor plan and target illumination levels.

The Jarvis HBL-A linear high bay series offers a dedicated 277-480V driver option for industrial facilities wired at higher voltages. No step-down transformer is required. The A51-A-G2 UFO series operates on 100-277V. Both voltage ranges are available with selectable wattage, allowing field adjustment without rewiring.

Jarvis LED high bays support 0-10V dimming and are compatible with external occupancy and daylight sensors. The fixtures accept standard 0-10V control signals for dimming to 10% or off. For integrated sensing, Jarvis offers occupancy and daylight harvesting sensors that mount directly into the fixture's sensor port, enabling automatic on/off and dimming based on motion and ambient light conditions.
