RAB Lighting H17 Series High Bay Accessory — Dome Wire Guard (150W)

The H17-DWG is an industrial-grade dome wire guard engineered to provide maximum physical protection for RAB Lighting H17 LED high bay fixtures. Designed specifically for the 150W models operating on universal 120-277V systems, this robust accessory shields the fixture's optics while allowing its full 22,000 lumens to pass through unimpeded. Its durable wire construction ensures critical lighting infrastructure remains safe from strikes and impacts in demanding environments.

Key Features

• Compatibility: Exclusively fits RAB Lighting H17 series LED high bays up to 150W.
• Protection: Shields the fixture's internal LED board and optics from large airborne objects and machinery strikes.
• Light Transmission: Open wire design ensures zero reduction in the fixture's native lumen output.
• Material: Constructed from heavy-duty, impact-resistant steel wire.
• Finish: Coated in a high-durability white powder finish to seamlessly match the host fixture.
• Weight: Lightweight design adds minimal strain to suspended mounting hardware.
• Passive Component: Requires no electrical modifications to the host luminaire.
• Attachment: Pre-drilled alignment points ensure perfectly centered and secure installation.

Typical Applications

• Commercial gymnasiums and indoor sports complexes.
• Warehouse aisles with heavy forklift traffic.
• Manufacturing facilities and industrial assembly plants.
• Aviation hangars and heavy equipment maintenance bays.
• Distribution centers requiring physical fixture defense.

Performance & Light Output

As a precision-engineered structural accessory, this wire guard is specifically designed to allow the host high bay fixture to perform at its maximum photometric efficacy. The wide spacing between the steel wires ensures that the raw lumens generated by the LEDs are not trapped or blocked, preventing unwanted shadowing. This guarantees that the workspace below receives the full intended brightness and light distribution.

Electrical & Controls

This unit is a completely passive physical accessory containing no internal electronics, wiring, or drivers. When installed, it fully relies on the electrical architecture of the host RAB Lighting fixture, accommodating its standard 120-277V power systems. The guard does not interfere with the host fixture's surge protection, power factor, or any integrated microwave and PIR sensor control modules.

Construction & Durability

Built to withstand the severe physical rigors of commercial and industrial environments, the guard provides a robust barrier against external impacts. The thick steel construction is highly resistant to deformation, ensuring long-lasting defense against errant sports balls, flying debris, and accidental machinery bumps. The white powder-coated finish protects the steel from rust and corrosion in unconditioned spaces.

Installation & Mounting

The wire guard is designed for rapid field installation directly onto the heat sink of the host high bay. The process involves aligning the mounting tabs on the guard with the corresponding attachment points on the fixture. Using standard provided hardware, contractors can securely fasten the guard in minutes without opening the electrical compartment or altering the primary mounting hooks and chains.
