VL-EXO-8231-XX Explosion-Proof Hanging Lamp for Hazardous Locations (50W–90W)
The VL-EXO-8231-XX Explosion-Proof Hanging Lamp is a pendant-mount industrial luminaire engineered for Class I Division 1/2 and ATEX/IECEx Zone 1/2 hazardous environments. Available in 50W, 60W, 70W, and 90W configurations, this lamp delivers high-efficacy LED illumination (≥130 lm/W) from a robust low-copper aluminum housing with a borosilicate glass globe lens for wide-angle distribution. The pendant installation style suits industrial workspaces where vertical clearance permits overhead suspension — including processing halls, tank farms, warehouse bays, and machinery rooms — providing 360° uniform illumination without shadows or hot spots that impede worker safety.

Application Environments
- Petroleum Refineries: Process unit work areas and pump houses requiring Class I Div 1 Group D illumination
- Chemical Processing: Reactor and mixing areas with hydrogen sulfide (Group C) or propane atmospheres (Group D)
- Offshore Platforms: Machinery rooms, compressor halls, and deck areas requiring ATEX Zone 1 rating
- Grain & Feed Mills: Interior of silos and conveying areas with Class II Group G combustible grain dust
- Paint Spray Booths: Class I Div 1 solvent vapor environments per NFPA 33
Frequently Asked Questions
- What wattage should I choose for a 5-meter ceiling height?
- For a 5-meter ceiling height with 3m × 3m grid spacing, the 70W configuration (9,100 lm) typically achieves 50–60 lux at floor level — suitable for general process area illumination per IES RP-7 recommendations for industrial facilities. For task areas requiring 150+ lux, use 90W or reduce grid spacing.
- Is the VL-EXO-8231 rated for Group B (hydrogen) environments?
- Yes. The ATEX IIC and NEC Group B ratings cover hydrogen gas atmospheres, making the VL-EXO-8231-XX suitable for battery rooms, electrolysis facilities, and hydrogen generation areas where Group B classification applies.
- Can this lamp be installed in wet outdoor locations?
- Yes. The IP66 rating (dust-tight, protected against high-pressure water jets) qualifies the VL-EXO-8231-XX for covered outdoor locations including offshore weather decks, chemical plant exterior processing areas, and loading docks. For fully exposed outdoor installation, a weatherhood accessory is recommended.
- What is the recommended replacement schedule for the LED module?
- The LED module is rated L80 ≥50,000 hours, meaning it retains 80% of initial lumen output at 50,000 operating hours. At continuous operation this equates to approximately 5.7 years. Annual photometric surveys using a light meter are recommended to confirm maintained illuminance levels meet OSHA and NEC minimum requirements.
