The Q1000T3/CL-277V is a 1000W double ended halogen lamp designed for high-voltage applications operating at 277V. Built on the industry-standard R7S base and measuring 10.08 inches (256mm) in length, this T3 tubular lamp delivers powerful halogen illumination suited for commercial and industrial fixtures that demand consistent, high-output performance. With a rated average life of 2,000 life hours, this lamp provides dependable service in demanding environments such as work lighting, stadium and arena fixtures, outdoor floodlighting, and construction or industrial task lighting. The clear glass envelope allows full light output and is optimized for use in enclosed or reflector-style luminaires designed for double ended halogen sources. The 277V rating makes it compatible with the single-phase commercial building voltage commonly found in North American commercial installations, reducing the need for step-down transformers. Each lamp is sold individually and is a direct replacement for standard 1000W T3 double ended halogen lamps with an R7S base at 256mm length.
