Buying Guide
- Certification and safety: Prioritize UL 844 for Class I Division II, and ensure ATEX compatibility if your site requires it. Confirm IP rating (IP66 is common) for dust and water ingress protection.
- Lumens and efficiency: Compare lumens per watt to estimate energy savings. High bay fixtures in hazardous locations typically range from 7,000–33,000 lumens depending on size and height of installation.
- Temperature range and durability: Look for wide operating temperatures (-40°C to 60–65°C) and rugged enclosures to handle vibration, chemicals, and moisture exposure.
- Installation options: Check mounting compatibility (3/4″ NPT, wall mount, brackets, suspension) and available dimming or control options (0-10V, PWM, Rx).
- Voltage compatibility: Ensure the fixture covers your building’s electrical system (120–277V or 120–480V ranges) and allows for future expansion.
- Maintenance and lifespan: Target fixtures with long-rated lifespans (50,000 hours or more) to minimize maintenance downtime and replacement costs.
- Color temperature and color rendering: 5000–5700K daylight color improves contrast and safety. Consider CRI if precise color recognition is important for inspections or assembly tasks.
- Cost of ownership: Beyond upfront price, account for energy savings, maintenance intervals, and any required mounting hardware or drivers.
