Frequently Asked Questions
Is the VL-EXS8231-XX rated for Class I Division 1?
Yes. certified for Class I Division 1, Groups B, C, D and Class II Division 1, Groups E, F, G. Also ATEX/IECEx certified for Zone 1 and Zone 21 – covering both gas-vapor and combustible dust hazardous environments.
What is the wattage and lumen output?
Available in 50W (6,500 lm), 65W (8,450 lm), and 90W (11,700 lm) variants at 130 lm/W efficacy – typically 60 to 70 percent more energy efficient than equivalent HID explosion-proof high bays.
Can this replace an existing HID explosion-proof high bay?
Yes. Designed for direct retrofit of 150W to 250W HID (metal halide, high-pressure sodium) explosion-proof high bay fixtures using the same mounting footprint and conduit entry points – no rewiring required.
What is the service life?
L70 rating of 50,000 hours (output remains above 70 percent of initial lumens). At continuous 24/7 operation, this is approximately 5.7 years between maintenance cycles – dramatically reducing maintenance overhead in hard-to-reach hazardous area locations.
