Interior High Bay Linear Fluorescent Fixtures Can Cut Your Energy Costs by 50%
Standard metal halide fixtures have long been the dominant technology in high bay lighting applications, but developments in fluorescent fixtures now make it possible to reduce energy costs and improve lighting quality by installing high bay fluorescent fixtures. High bay applications are often found in warehouses, schools, gymnasiums, storage rooms, large retail stores, and other building types with ceilings 15 feet and above.
In conjunction with PG&E, Vision Lighting offers a program to California businesses to replace standard fixtures with energy-saving T5 high output high bay fixtures at no or low cost. Contact Wade Erickson for more details.

ADVANTAGES OF LINEAR HIGH BAY FLUORESCENT FIXTURES
- ENERGY SAVINGS: Linear high bay fluorescent fixtures can provide up to 50% energy cost savings over standard metal halide systems. At 4,000 annual operating hours, operating cost of a fluorescent fixture ranges from $133 to $140 per year, compared to approximately $275 for each 400-Watt standard metal halide. At $0.15 per kWh, that’s an estimated savings of up to $142 per fixture per year.
- INSTANT ON AND INSTANT RESTRIKE: Unlike standard metal halides, fluorescents turn on instantly, even after a power interruption. The immediate illumination provided by fluorescents can improve safety and productivity as compared to the slower strike and restrike times associated with standard metal halides.
- OCCUPANCY SENSORS AND PHOTOCELLS: Additional energy savings can be realized by pairing a fluorescent system with sensor controls that switch lights off when not needed.
- CONSISTENT LIGHT OUTPUT: Fluorescents provide 90% of original light output over their rated lamp life while standard metal halide lamps can degrade by nearly 49% over their rated lamp life.
- ENHANCED LIGHT QUALITY: Fluorescent lamps do not suffer from color shift while many standard metal halides can vary in color both initially and over time. Consequently, when standard metal halide fixtures are adjacent to each other, some may appear pinkish while others may appear bluish or greenish.
- IMPROVED COLOR: Fluorescents offer better color rendering, which can make retail displays more attractive and improve productivity and worker satisfaction in warehouses and manufacturing spaces. On the Color Rendering Index (CRI) scale, sources with ratings closer to 100 render colors more accurately in comparison to a standard reference source. While standard metal halide lamps rate between 62 and 70 CRI, 800 series fluorescent lamps rate between 82 and 86 CRI.
- BETTER LIGHT DISTRIBUTION: Because of the linear nature of the lamps, fluorescent fixtures can be designed to provide more uniform light within a space and fewer shadows than point-source standard metal halide lamps.
