Our Brightest: 2ft Linear LED Retrofits

2ft LED retrofits with a luminous efficacy of at least 145 lm/W can upgrade your fluorescent fixtures with ultra-bright light output while cutting your monthly lighting cost in more than half. Even when upgrading from older-model LED tubes, you'll realize a 45% to 88% increase in efficiency over the 100 lm/W (or less) retrofits that were available 5 or more years ago.
