New and Underutilized Technology: Super T8 Lighting
The following information outlines key deployment considerations for super T8 lighting within the Federal sector. This information spans:
Super T8 lamps are 32W T8 lamps, but have a barrier-coat design, high lumen maintenance (88% to 92% end-of-life lumens), long service life, and high light output (3,100+ initial lumens as opposed to 2,850 for a standard T8). Combining super T8 lamps with low ballast factor ballasts (BF of ≤ 0.77) on a one-for-one replacement will reduce energy 15% to 20%.
Super T8 lighting is applicable in almost any fluorescent lighting system in most building types and settings.
Key Factors for Deployment
Super T8 technology can be used in combination with other fluorescent lighting based measures, such as low ambient/task lighting, delamping configurations, and daylighting controls.
Spectrally enhanced lighting should be considered as an alternative when considering super T8 lamps.
Federal energy savings, cost-effectiveness, and probability of success are ranked 0-5 with 0 representing the lowest ranking and 5 representing the highest ranking. The weighted score is ranked 0-100 with 0 representing the lowest ranking and 100 representing the highest ranking.
