New and Underutilized Technology: Efficient High Bay Fluorescent Lighting

The following information outlines key deployment considerations for efficient high bay fluorescent lighting within the Federal sector. This information spans:

• Benefits
• Application
• Key Factors for Deployment
• Ranking Criteria
• Resources

Benefits

Efficient high bay fluorescent lighting can include either T5 or T8 fluorescent lighting systems for high-bay applications currently using metal halide fixtures. Fluorescent fixtures offer better light distribution, better light maintenance over the life of the lamp, improved color quality, and on-off control (re-strike time) with lower energy consumption.

Application

Efficient high bay fluorescent lighting is applicable for facilities containing high bay areas.

Key Factors for Deployment

Federal agencies must evaluate relative costs, benefits, and application of the three major high bay technologies before making a deployment decision. These technologies include HID electronic, fluorescent, and LED lighting.

Ranking Criteria

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.
