Appleton's Mercmaster LED luminaire is rated for hazardous industrial locations
Appleton is offering an energy-efficient alternative to traditional HID and high-intensity fluorescent lighting with its Mercmaster enclosed and gasketed LED luminaire, the company's first LED (light emitting diode) fixture The Mercmaster brings LED technology's benefits to industrial, marine and heavy commercial customers.
The Mercmaster LED features a compact, low-profile that is well suited for installation in low clearance areas. The fixture is rated by the NEC as Class I, Div. 2, and Class 1, Zone 2.
Unlike HIDs that requires a reflector to control light direction, the LED precisely directs its light to where it is needed most without the use of external optics, resulting in efficiencies up to 80%.
The NEMA 4X-rated housing, guards and mounting hoods are copper-free cast aluminum protected by an epoxy powder coat, a combination that results in a unit that can withstand punishing weather, salt water, corrosive chemicals and high ambient temperatures. All exposed hardware is stainless steel, and the fixture's construction is free of any hazardous materials, including mercury. Hinge and bolt construction assures 360º compression at all points on the ballast housing gasket for positive sealing.
In addition, the fixture's aluminum heat sink dissipates heat more effectively than standard steel, while its threaded polycarbonate lens better safeguards the LED cluster than the glass lenses deployed in competitor's fixtures. Another performance benefit of LEDs is that they feature no filament that can be damaged by vibrations or sudden shocks, further reducing the need for maintenance.
