Project overview

TBCS approached LED Lighting Supply to replace their 400-watt metal halides with MLLG-LED-HBC-200-5-120 (set at 150 Watts). With this LED UFO High Bay, you get about 150 lumens per watt, which is 87.5% more efficient than the 400-watt metal halide fixtures.

Our approach and lighting plan

Our recommendation for the MLLG-LED-HBC-200-5-120 (set at 150 Watts) was based on all the information we received about TBCS’ gymnasium, including the locations of the existing fixtures, mounting height, and footcandle requirements. Having selected these high bays, we were able to develop a lighting plan. This would give them a visual representation of what they could expect their facility to look like with our fixtures installed.

Project Data

Increase in efficiency
20 year
Increase in life expectancy


The upgrade from metal halides to LEDs not only increased fixture efficiency by 87.5% for TBCS, but it also increased life expectancy. With the new fixtures, this gym can save money by using more efficient fixtures and, by switching to LEDs, they also extended the life expectancy by 20 years.

Customer Feedback

We are absolutely thrilled with our gym lighting! The best parts are (1) the instant on and off (no warming and cooling cycles), (2) they give brighter light, and (3) more evenly distributed light.

They are perfect for our application.
