The ultra-efficient optical system of the T271L Arc™ LED Series track fixture maximizes efficiency while minimizing fixture depth, thereby creating a high-performance track light with a unique, attractive aesthetic. It approximates the light output and distribution of a 60-75W PAR30 halogen lamp, while consuming about 20% of the energy with a 50,000-hour rated life. It is available in four color temperatures and three CRI options, including SpectralWhite. An array of optional accessories are available for use with the Arc LED including a hexcell louver that optimizes visual cutoff.
