Intended Use

The classic architectural shape of the MRW LED was designed for applications such as hospitals, schools, malls, restaurants, and commercial buildings. The long life LEDs and driver make this luminaire nearly maintenance-free.

Construction

The single-piece die-cast aluminum housing integrates secondary heat sinks to optimize thermal transfer from the internal light engine heat sinks and promote long life. The driver is mounted in direct contact with the casting for a low operating temperature and long life. The die-cast door frame is fully gasketed with a one-piece solid silicone gasket to keep out moisture and dust, providing an IP65 rating for the luminaire.

Finish: Exterior parts are protected by a zinc-infused Super Durable TGIC thermoset powder coat finish that provides superior resistance to corrosion and weathering. A tightly controlled multi-stage process ensures a minimum 3 mils thickness for a finish that can withstand extreme climate changes without cracking or peeling. Available in both textured and non-textured finishes. Standard Super Durable colors include dark bronze, black, natural aluminum, white and sandstone.

Optics

Precision-molded acrylic lenses are engineered for superior distribution, uniformity, and spacing in wall-mount applications. Light engines are 4000K (70 CRI). The MRW LED has zero uplight and qualifies as a Nighttime Friendly� product, meaning it is consistent with the LEED� AND Green Globes� criteria for eliminating wasteful uplight. Choice of three optimized distributions: Type II, Type III, and Type IV.

Electrical

Light engine(s) consist of 10 high-efficacy LEDs mounted to a metal-core circuit board and integral aluminum heat sinks to maximize heat dissipation and promote long life (100,000 hrs at 25?C, L77). Class 2 electronic driver has a power factor >90%, THD <20%. Easily-serviceable surge protection device meets a minimum Category B (per ANSI/IEEE C62.41.2).

Installation

A universal mounting plate (also used on CSXW and architectural scones in HID or CFL) with integral mounting support arms allows the fixture to hinge down for easy access while making wiring connections. The integral bubble level on the mounting plate provides assistance for level placement on every installation.

Listings

CSA certified to U.S. and Canadian standards. Light engines are IP66 rated; luminaire is IP65 rated and suitable for wet locations when mounted with the lenses down. WLU option (coming soon) offers wet location listing in �up�orientation. Rated for -30?C minimum ambient.
