A company had installed new energy-efficient vapor tight linear fluorescent fixtures to replace existing HID lighting.
After installation, lifeguards reported glare on the surface of pool which impaired ability to see bottom of pool.
GOAL: Identify solution to eliminate pool surface light reflection without replacing fixtures.
- Met with YMCA facility manager and organization’s district managers.
- Took light level measurements and photos.
- Researched light science, and theorized that light with high wave length might have better ability to permeate water surface.
- Recommended change from 5000 Kelvin lamps to 3500 Kelvin lamps.
- Developed two additional solutions:
- Had opaque metal bands fabricated that could block light emitted from sides of lens.
- Had grid baffles fabricated that could direct light downward.
- Kelvin change was implemented and solved the problem. Additional alterations weren’t necessary.
YMCA was pleased with the outcome, especially since the solution was cost-effective.
