An optional PIR sensor (sold separately) can enhance control in large facilities where occupancy-based lighting is beneficial.
Buying Guide: Key Purchase Considerations
- Ballast bypass vs. direct-wire: Many EX39 LED replacements require bypassing or bypass-ready configurations. Confirm fixture compatibility and wiring safety before installation.
- Lumens and beam angle: Larger spaces benefit from higher lumen outputs and broader beam spreads. Consider whether a focused or omni-directional beam better suits your layout.
- Color temperature: 3000K to 5000K ranges affect task visibility and comfort. Choose 3500K-4200K for general work areas or 5000K for high-contrast tasks in warehouses.
- CRI and efficiency: Higher CRI improves color rendering, aiding accurate work in shops. Look for lumen efficiency and power factor near 0.95+ for reliable operation.
- Lifespan and maintenance: Longer rated life reduces replacements and downtime. Consider built-in surge protection in areas with electrical fluctuations.
- Voltage compatibility: Most EX39 LEDs operate across 120-277V. Verify your site’s voltage and ensure ballast bypass is safe and compliant with local electrical codes.
- Cost of ownership: Compare initial cost, LED life, energy savings, and maintenance needs. Higher upfront costs can be offset by long-term energy and labor savings.
- Warranty and support: Ensure a solid warranty period and accessible customer support for industrial-grade lighting investments.
In industrial settings, selecting EX39 base LED bulbs often revolves around achieving bright, reliable light while simplifying retrofit work. The listed options balance high lumen output, ballast considerations, and durability to suit workshops, warehouses, and manufacturing floors where visibility and efficiency drive performance.
