​T5 Lighting Retrofit at Junior High School Campus Gyms


Estimated Project Timeline

May 2016August 2016

Project Description

Provide for change out of existing metal halide lighting to T5 lighting at six (6) Junior High campus gymnasiums:


This group of work will update all remaining Junior High Gyms to current Standard.

  • Upgrading these systems will save “Energy”.

  • The replacement/ upgrade of the lighting will Increase the quality of the lighting exponentially.

Background & Justification

The District has made the T‐5 the new lighting standard for all gymnasiums in new facilities. The T‐5 fixtures increase the lighting level to meet U.I.L. Guidelines and provide a quality environment as well as energy savings. 400 watt metal halide light fixtures typically are turned on in the early morning and not shut off until the day is over, due to the re‐strike time of approximately 15‐20 minutes. T‐5 lights do not have the re‐strike time disadvantage and are occupancy sensor friendly.

We are currently using the following method controlling the T‐5 fixtures in the gymnasiums retrofitted with (6) lamp fixtures.

  1. Occupancy sensors operate the light only when occupied.

  2. During practice the fixture can operate at 33% of capacity.

  3. During game conditions the fixture is switched to 100% capacity.

Note: Each step reduces energy consumption.
