Product Description
The Q1A Series LED luminaire is a dust-ignition-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 II, Division 1 covers areas where combustible dust is present continuously or intermittently during normal operation — typical applications include grain elevators, flour and feed mills, coal handling, and metal-powder plants.
