Product Description

The Q1A Series LED luminaire is an explosion-proof choice for hazardous applications. They can be used in locations where moisture, dirt, dust, corrosion and vibration may be present, or areas where wind, water, snow or high ambient can be expected. Featuring various shapes of driver box cover, this series is designed to meet different requirements of installations.

Class I, Division 2 covers hazardous gas and vapor environments where ignitable concentrations are present only under abnormal conditions — typical applications include oil & gas processing, paint booths, chemical handling, cannabis extraction, and pharmaceutical manufacturing.
