LED Hazardous Location High Bay 200 Watt 27600 Lumens 80+ CRI Class 1 Division 2 Approval IP66 Rating 110 Degree Beam Angle Corrosion Resistant Shatterproof Tempered Glass Lens 120-277V

What environments typically require a hazardous location high bay with Class I, Division 2 approval?

Class I, Division 2 luminaires are commonly specified where flammable gases or vapors are not normally present in an ignitable concentration, but may exist under abnormal conditions such as equipment failure or maintenance activity. Typical applications include fuel storage support areas, solvent storage rooms, chemical processing support zones, paint mixing areas, and certain wastewater or industrial utility spaces when the site classification calls for C1D2 equipment.

What does the T4 temperature code indicate for fixture selection?

T4 indicates the luminaire is rated so its maximum external surface temperature does not exceed the T4 limit under rated conditions. This is used during hazardous location design to reduce ignition risk by keeping surface temperatures below the autoignition threshold specified for the classified materials at the site. Site classification and material data should be confirmed by the engineer of record.

What does 27,600 lumens at 200W translate to in efficacy?

The fixture produces 27,600 lumens at 200W, which calculates to 138.0 lm/W. Maintained workplane results depend on mounting height, spacing, room geometry, and reflectances.

How does a 110° beam angle affect layout in high-ceiling hazardous areas?

A 110° distribution is designed to provide controlled coverage compared to ultra-wide optics. In high-bay layouts, it supports better control of light where the work area is more defined and can reduce spill into adjacent zones. Fixture spacing should be verified using the photometric file to meet the project’s foot-candle and uniformity targets.

How does the IP66 rating differ from lower IP ratings in industrial environments?

IP66 indicates dust-tight construction and protection against powerful water jets. This rating is commonly specified where airborne particulates are heavy or where washdown, wind-driven water, or high-exposure moisture conditions are expected.

What does wet-location rating cover for this high bay?

Wet-location rating supports installation where the fixture can be exposed to direct moisture, including open-sided structures and industrial areas where water spray or dripping can occur. Confirm installation details and wiring methods match the listing requirements for the environment.

What does a shatterproof tempered glass lens contribute compared to polymer optics?

Tempered glass supports impact resistance and chemical compatibility in environments where solvents, oils, or airborne contaminants can degrade plastics. In hazardous location spaces, glass also supports long-term optical stability where cleaning agents and temperature cycling are common.

How does corrosion-resistant construction matter in chemical or coastal industrial sites?

Corrosion-resistant construction reduces degradation of the housing and fasteners in environments with salt exposure, chemical vapors, or frequent washdown. This helps maintain sealing integrity over time, which is directly tied to environmental protection performance.

What does the 120–277V input range support for industrial electrical planning?

The 120–277V driver supports common commercial and industrial branch circuit voltages, including 277V lighting circuits. This can simplify standardization across sites that use different service voltages.

What does 5000K CCT support for hazardous location task visibility?

5000K is commonly specified where higher contrast supports hazard recognition, labeling visibility, and inspection tasks. For facilities with camera-based monitoring or detailed identification requirements, 5000K is often selected to support consistent visual conditions.

What does a minimum operating temperature of -4°F indicate?

A minimum operating temperature of -4°F indicates the driver and LED system are rated for cold-weather starts and operation down to that ambient temperature. For colder sites or wind-exposed installations, confirm expected ambient conditions and any manufacturer guidance on cold operation.

What should be tracked for maintenance planning based on rated life and warranty?

The fixture is rated for 50,000 hours and includes a 5-year limited warranty. For maintenance planning, document the installed locations by zone classification and circuit, and retain the submittal and photometric package so any replacements match the hazardous rating, optic performance, and electrical characteristics.
