How It Compares to Metal Halide

When upgrading from metal halide systems, this LED fixture provides immediate advantages in both performance and operating costs. Unlike traditional 400 or 1000 watt metal halide fixtures that require lengthy warm-up periods and frequent lamp replacements, this LED solution delivers instant full brightness and maintains consistent light output throughout its 50,000-hour lifespan. From a cost standpoint, the 150-watt power consumption represents substantial energy savings while the polycarbonate lens construction eliminates the fragility concerns associated with metal halide glass components.

Major Benefits

Energy Savings

With its 90% power factor and maximum 20% total harmonic distortion, this fixture maximizes energy efficiency while minimizing electrical system stress. The 150-watt consumption paired with 0-10V dimming capability allows facilities to optimize energy use based on occupancy and task requirements, significantly reducing operational costs compared to legacy high bay systems.

Light Output & Visibility

The 5000K color temperature with 80+ CRI ensures accurate color rendering and reduces eye strain in work environments. Additionally, the 120-degree beam angle provides uniform light distribution that eliminates dark spots and shadows commonly found with directional metal halide fixtures, improving safety and productivity across the illuminated area.

Operating Stability

Engineered to handle demanding conditions, the die-cast aluminum housing dissipates heat effectively while the IP65 rating protects internal components from dust and moisture intrusion. In practice, this translates to consistent performance without the lumen depreciation and color shifting typical of traditional high intensity discharge lighting systems.

Installation Considerations

For most installations, the standard eye-hook mounting provides secure suspension from ceiling structures, while the surface mount option accommodates applications where direct attachment is preferred. The 5-foot power cord and 8-inch dimming lead offer installation flexibility, and the 277-480V input voltage accommodates most commercial electrical systems without requiring additional transformers or ballasts.
