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" -bayspaces 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 JAFech 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.
