Perimeter and security lighting require excellent control and uniformity. Light trespass and glare must be minimized as should pockets of shadow. The Wallpack IV luminaire excels at this, requiring fewer units to achieve needed light levels. This control readily transfers to lighting other areas such as uniflow garages and underpasses for the most economical solutions. Wallpack IV features a borosilicate glass refractor for precise illumination - and it never yellows from heat or UV. Sockets are field adjustable for maximum control of light throw. All housings are formed of die cast aluminum for corrosion resistance. This is complemented by a seven stage polyester powder paint finish in a wide variety of colors. Vandal resistant options are available.
