The WAL-M-500-120 is a quartz halogen lamp that can magnetically mounted to ferrous metal surfaces. With a compact design and 500 W of lighting power, the quartz halogen lamp can be easily mounted on tank walls, iron walkways and similar metal surfaces and will remain firmly in place even under demanding work conditions, the company says. The light is designed to work with common 120 V a.c. current, and can illuminate over 3,000 ft2 of work space. The lamp body is constructed with aluminum with a tempered glass lens. Included with the lamp is 25 ft of chemical- and abrasion-resistant cord with a straight-blade plug for easy connection to standard wall outlets. — Larson Electronics LLC, Kemp, Tex.
