F900 HIGH-BAY FLUORESCENT FIXTURES SERIES

The F900 HIGH-BAY Series of "T5" and "T8" fluorescent fixtures have many unique features including low-energy usage and high-efficiency. Our High-Bay series, introduced in 2004 have been made possible by recent advances in fluorescent lamp and ballast technology. These fluorescent High-Bay fixtures have proven to be an excellent cost effective alternative to traditional HID High-Bay without their associated problems.

The high-intensity discharge (HID) light sources, such as metal halide and high pressure sodium lamps, have long dominated the market for lighting indoor spaces with high ceilings. These "high bay” spaces are typically found in warehouses, factories, large retail stores, and athletic facilities. In recent years, however, improvements in fluorescent lamps and the emergence of new high-intensity fluorescent fixtures have made fluorescent lighting the most cost-effective choice for lighting high indoor spaces. These high-intensity fluorescent systems are more energy-efficient than HID solutions and feature lower lumen depreciation rates, better dimming options, virtually instant start-up and re-strike, better color rendition, and reduced glare.

The JAFtech fluorescent fixtures designed for high-bay applications have eight distinct advantages over older inefficient HID fixture technology:

1. Over 50% lower energy consumption - As an example a 400 watt HID High-bay fixture uses 455 watts of electrical power whereas a six lamp "T8" High-bay fluorescent fixture uses only 217 watts.
2. Lower lumen depreciation rates


3. Better dimming options - "T5" and "T8" High-bay fixtures with multiple lamps and ballasts can be partially controlled by either sensor-switch or building management systems.
4. Instant start-up and re-strike - It is well-known that HID fixtures of all types require a cool down period before re-strike, sometimes as long as 15 minutes. This is not the case with fluorescence fixtures.
5. Better color quality (CRI) - The average metal-halide lamp is rated approximately 70 on the color rendering index whereas "T8 and "T5" are rated between 85 and 90 on the scale. High-pressure sodium and low pressure sodium has the poorest ratings at 22 and 5 respectively.
6. More pupil lumens and reduced glare - This is a measurement of how effectively the eyes see the light that is emitted. The pupil is more receptive to light at the blue end of the spectrum.
7. Higher fixture efficiency - Standard 400 want metal halide High-bay fixtures are rated at about 70% efficient whereas Jaftech's "T5" and "T8" range as high as 95%.
8. With multiple fluorescent lamps in each fixture, dark spots will be eliminated. - Lamps operate in parallel consequently if one or more lamp goes out the remainder will remain in operation.
