300 / 400 / 500 Watt Adjustable UFO High Bay | 44900 to 79100 Lumens | 4000K / 5000K | 100-277V
This UFO high bay fixture is a strong choice for large indoor spaces needing high, adjustable light output, such as warehouses, manufacturing plants, and distribution centers, especially where legacy 1500 or 2000 watt metal halide fixtures are being replaced. Its selectable wattage and color temperature allow on-site tuning for evolving requirements, while the 90° beam angle delivers focused, uniform illumination at high mounting heights. The IP65 and IK08 ratings, polycarbonate lens, and aluminum housing ensure durability in dusty, damp, or moderately impacted environments. Eye-hook mounting simplifies installation, and the 0-10V dimming supports energy management. Not intended for hazardous locations.

Product Lighting Layout Estimator
Use this estimator to calculate approximate fixture count, spacing, and average foot-candles for a simple rectangular space using the selected LED fixture. Enter your room dimensions, mounting height, target foot-candles, light loss factor, and room light use factor to generate a preliminary lighting layout.
Project Inputs
Estimated Results
Estimated average foot-candles are preliminary and should be verified with a lighting plan for project-critical applications.
Room Light Use Factor: Suggested starting points: open warehouse 0.85–0.90, clean light-colored space 0.75–0.85, typical warehouse 0.65–0.75, racked or obstructed space 0.50–0.65, dark or complex space 0.40–0.55.
Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data to improve the visual floor-level light distribution. When IES photometry is not available, the estimator uses a simulated beam model based on lumens, mounting height, room light use factor, light loss factor, and beam angle.
Preliminary Estimate Only: This estimator is intended for simple square or rectangular spaces. Actual light levels may vary based on fixture optics, mounting conditions, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements.
This estimate is a starting point. Warehouses, industrial facilities, hazardous locations, sports areas, schools, healthcare spaces, public areas, and code-sensitive projects may require a reviewed lighting layout before purchase or installation.
