LED UFO High Bay 100W – 150 lm/W – 4000K – 90° – Sosen Driver – 1-10V Dimmable | 5-Year Warranty

Why choose the LED UFO High Bay 100W

At 150 lm/W, this UFO high bay produces more usable light per watt than most comparable fittings on the market, without the premium price of a branded alternative. The compact UFO form factor simplifies installation on hook or pendant mounts, while the Sosen driver and 1-10V dimming interface make it compatible with standard building management and daylight harvesting systems. A 5-year warranty backs every unit.

• Efficiency: 150 lm/W means 15,000 lm from just 100W, cutting energy consumption by up to 60% compared with a 250W metal halide equivalent.
• Light quality: A CRI of Ra>80 renders colours accurately enough for picking, inspection and assembly tasks where visual detail matters.
• Driver: The Sosen driver is a proven industrial-grade component with built-in surge protection, supporting 1-10V dimming for integration with occupancy sensors or BMS controls.
• Warranty: A 5-year warranty on the complete fitting gives facility managers and installers a clear, low-risk maintenance horizon from day one.

Where to use it

The 100W UFO high bay is well suited to mounting heights of 5 to 9 metres, covering logistics warehouses, production halls, car workshops, sports halls and large retail stockrooms. At 8 metres, a single fitting typically achieves 300–400 lux on the working plane, making it appropriate for general industrial tasks. Smaller units can be spaced at 4–5 metre centres for uniform coverage across open-plan floor areas.

What the specifications mean in practice

• 150 lm/W: One of the highest efficacy ratings in this wattage class, directly reducing your electricity bill compared with older HID or fluorescent high bays.
• 15,000 lm: Equivalent output to a 250W metal halide fitting, so you replace existing fittings one-for-one without redesigning your layout.
• 90° beam angle: Concentrates light downward onto the working area rather than scattering it sideways, making it most effective at mounting heights between 5 and 9 metres.
• 4000K: Neutral white light that keeps the space bright and alert without the harshness of cool white, suitable for both task areas and general circulation.
• 1-10V dimmable: Allows output to be reduced to around 10% via a standard 1-10V signal, enabling daylight linking, occupancy control or manual scene setting through a compatible controller.

Installation and compatibility

The UFO high bay ships with a 1-metre cable and is designed for hook or pendant suspension from a standard ceiling mount. Connect the 1-10V dimming wires to a compatible controller or BMS input for variable output. No additional driver is required.
