1. What is an LED retrofit kit for fluorescent fixtures?
An LED retrofit kit is a complete LED lighting module designed to upgrade an existing fluorescent fixture while retaining the original housing. It provides a more comprehensive upgrade than a basic tube replacement, with options such as selectable wattage, adjustable color temperature, dimming, sensor control, and emergency backup.
2. Can LED retrofit kits be installed in existing T8 fluorescent fixtures?
Yes. FY Lighting LED retrofit kits are designed to fit into existing T8 light channels, so the original fixture housing does not need to be completely replaced. This helps reduce installation time, labor costs, material waste, and disruption to normal operations.
3. How are LED retrofit kits different from standard LED T8 tubes?
Standard LED T8 tubes are mainly used as direct lamp replacements. An LED retrofit kit upgrades the fixture as a complete lighting system, offering higher efficiency, field-selectable wattage and CCT, 0–10V dimming, sensor compatibility, and optional emergency lighting functions.
4. What are the wattage, lumen output, and efficacy of the LED retrofit kit?
The LBS-C Series LED retrofit kit is rated at 36W and delivers up to 5,760 lumens, providing an efficacy of 160 lm/W. It also features a 120-degree beam angle for broad and even illumination in commercial and industrial spaces.
5. Are the wattage and color temperature adjustable?
Yes. The LED retrofit kit uses DIP switches to adjust the wattage and color temperature for different ceiling heights, room sizes, and lighting requirements. The available color-temperature range is listed as 3000K to 5000K, helping reduce the number of separate models that need to be stocked.
6. Does the LED retrofit kit support sensors and dimming?
Yes. The retrofit kit supports 0–10V dimming and can be configured with a two-in-one daylight and microwave motion sensor. These controls allow the fixture to reduce output or switch off when sufficient daylight is available or when the space is unoccupied.
7. Is emergency backup available for the LED retrofit kit?
Yes. An emergency driver and battery pack are available as optional accessories. The emergency system can provide temporary lighting during a power outage, making the retrofit kit suitable for commercial and industrial projects that require emergency illumination.
8. What voltage range does the LED retrofit kit support?
The LED retrofit kit is available with AC 100–277V or AC 120–347V input options at 50/60Hz. This wide-voltage compatibility makes it suitable for a variety of commercial, industrial, and multi-site retrofit projects.
9. Where can LED retrofit kits for fluorescent fixtures be used?
LED retrofit kits can be used in assembly shops, CNC machining facilities, production workshops, warehouses, offices, schools, retail stores, hospitals, and other locations that already have fluorescent linear fixtures installed.
10. What certifications and warranty are available?
The product specifications list DLC, UL, and CE certifications. The retrofit kit is also listed with a rated lifespan of more than 50,000 hours at L70 and a five-year warranty, supporting long-term commercial and industrial retrofit projects.
