## Long description

Synergy21 S21-LED-UFO0051 is a 236 W LED high-bay bulb that provides 30,680 lumens of cool white light at 6500 K with a colour rendering index of 80. Intended for industrial and large indoor spaces, it offers a 90° beam angle and a rated lifetime of 50,000 hours, delivering steady, energy-efficient illumination for general and task lighting in warehouses, factories and similar facilities.
Advantages
The high lumen output combined with 236 W power makes this LED high-bay suitable for bright, wide-area illumination while consuming less energy than many traditional discharge lamps. A long rated lifetime of 50,000 hours reduces maintenance and replacement cycles. The 6500 K cool white colour temperature and CRI 80 provide clear, neutral-to-cool lighting suitable for inspection and task-focused environments. The 90° beam angle concentrates light for targeted coverage in high-ceiling spaces.
Suitable for
Warehouses and storage halls
Manufacturing floors and industrial plants
Large retail spaces and showrooms
Sports halls and gymnasiums with high ceilings
Workshops and maintenance areas
When it may not be suitable
This bulb’s cool 6500 K light is not ideal for environments that require warm, cosy lighting or for settings where colour-critical tasks demand a higher CRI than 80. It may be unsuitable for very narrow or highly decorative indoor spaces where a wide-area, utilitarian high-bay fixture would overwhelm the aesthetic.

How to use
Install the Synergy21 LED high-bay in appropriate high-ceiling fixtures or pendant mounts following the luminaire manufacturer’s instructions and local electrical regulations.

Use with suitable drivers or ballast adapters if required; switch to power after secure mechanical and electrical connections are confirmed. Regularly inspect mounting points and connections during routine maintenance.
What to consider before purchase
Ceiling height and mounting type to ensure correct beam coverage
Required lumen output and spacing for the intended area
Desired colour temperature and whether 6500 K is appropriate
Whether CRI 80 meets colour accuracy needs for tasks
Compatibility with existing fixtures, drivers or dimming systems
Usage recommendations
For best results in warehouses and industrial halls, plan fixture spacing and mounting height to achieve uniform illuminance.
