El Secundo, California-based International Rectifier Corp. (IR), has introduced a single-chip fluorescent lamp ballast device with an active, critical conduction mode, boost-type power factor correction method. High power factor improves electrical equipment efficiency. The IR2167 controls the entire electronic ballast, and combines lamp control, power factor correction and a 600V half-bridge driver. Ballast functions include control for preheating, igniting and powering a fluorescent lamp, and protection against such lamp failures such as open filament, lamp non-strike, brown-out, below resonance and end-of-life. The IR2167 enables ballast designs with power factors of 0.99, and THD lower than 10%, well within the IEC 6100-3-2 standards.

This article reports that up lighting, wall washing and task lighting are now possible with Huntington Beach, California-based Bartco Lighting Inc.'s new BAM series arm mount kits. Three mounting systems are available for several of the company's remote ballast display luminaries.
