Buying Guide: Explosion Proof High Bay Lighting Essentials
Targeted questions help narrow choices. Consider these factors when selecting explosion proof high bay lighting:
- What hazardous location rating do you need? Look for UL 844 and Ex certifications relevant to your zone (Class I Division 1 or Division 2, Zone 1/2).
- What ambient conditions will the light face? Temperature range, humidity, dust, and chemical exposure influence housing material and seals (IP66 or better, corrosion resistance).
- How much light output is required? Compare lumens and efficacy (lm/W) to balance brightness with energy use.
- What mounting method is feasible? Consider 0-10V dimming or PWM options, and whether wall, pendant, or bracket mounting fits your bays.
- Is long life and low maintenance important? A fixture with 50,000 hours or more reduces replacement frequency in hard-to-reach areas.
- Are surge protections and electrical compatibility accounted for? A wide input range (e.g., 120–480V) and 6KV surge protection improve reliability in variable power systems.
FAQ
What does UL844 certification verify?
UL844 confirms the fixture is designed for hazardous locations and meets safety requirements for explosion protection.
What is the difference between Class I Division 1 and Division 2?
Division 1 allows potential ignition sources to exist under normal operation; Division 2 limits them to abnormal conditions.
Why is IP66 important for high bay lights?
IP66 indicates total protection against dust and powerful water jets, which is crucial for outdoor or wet environments.
Should I choose a higher wattage than needed?
Higher wattage provides more lumens but increases costs; select based on bay height, reflectivity, and task lighting needs.
Can these lights be dimmed?
Many models support 0-10V/PWM dimming or Rx dimming, but confirm compatibility with your control system.
Are these suitable for outdoor refinery use?
Yes, provided the fixture has appropriate IP ratings, corrosion resistance, and certified explosion protection.
