Mercmaster LED Low Profile Luminaires provide a broad, evenly distributed light pattern that can be tailored in the field. This is the one harsh and hazardous location luminaire you can specify to meet all your low-mount application requirements without compromise. With three light output levels available, replacing HID fixtures up to 150 Watts is easy. They have a low weight, slimmer profile, smaller diameter and a robust design. Plus, no heat dissipation fins are required. They are perfectly suited for low mounting heights of 15 feet or less.
