Intended Use: The I-BEAM IBZ is an energy-saving fluorescent high bay solution that is an ideal one-for-one replacement of common metal halide high bay systems. Its configurable design supports many options and accessories that would satisfy almost any High Bay applic Listings: CSA Certified to U.S. and Canadian standards. Construction: The configurable design of the I-BEAM IBZ allows wireguards, lenses, tandem kits and sensors to be quickly installed in either our factory or in the field. The Integrated Modular Plug (IMP) feature further enhances the flexibility by allowing plug-and-pla Optics: The optics are engineered to be both highly-efficient and manage the heat generated by the lamps. The thermal vents convect heat rapidly to reduce dirt depreciation by pulling heat and contaminates out of the reflector and away from the lamps. Electrical: Using the most advanced ballast technology available, the Cool Running Plus- Technology ballast is integrated into the T5HO IBZ System to provide reliable operation in ambient environments up to 155 F (68 C). This ballast features independent lamp operation 49.00 L. 19.00 W. 3.00 H.
