Additional Information

Philips PL-L lamps are a legacy standard for high-end commercial facility management. While these lamps continue to provide reliable, high-quality light, LED 2G11 retrofits are available for users seeking to further reduce energy costs and eliminate mercury from their lighting systems. For immediate maintenance of existing fluorescent systems, the PL-L 50W remains a top-tier choice for performance and longevity.
