LED UFO High Bay 150/120/100W – 150 lm/W – 4000K – 90° – Moso Driver – DALI Dimmable – Power Adjustable | 5-Year Warranty

Why choose the LED UFO High Bay 150W

This fitting combines a high-output Moso driver with a power-adjustable design, letting you commission the same luminaire at 100W, 120W or 150W to match the exact lux requirement of each zone. The 90° beam angle concentrates light efficiently onto the working plane, reducing spill and the number of fittings needed to achieve target illuminance levels across large floor areas.

• Efficiency: At 150 lm/W, this high bay draws significantly less power than conventional discharge lamps while maintaining the same working-plane illuminance.
• Light quality: A CRI of Ra>80 renders colours accurately enough for quality control, picking operations and general industrial tasks without eye fatigue.
• Driver: The Moso driver is a proven industrial-grade component, backed by the same 5-year warranty as the luminaire itself for complete peace of mind.
• Control: Native DALI dimming allows integration into building management systems, enabling daylight harvesting and occupancy-linked scenes that reduce energy consumption further.

Where to use it

This UFO high bay is well suited to mounting heights between 6 and 12 metres in warehouses, logistics centres, manufacturing halls and indoor sports facilities. At 150W and 22,500 lumens, a single fitting typically covers 25–40 m² at 300–500 lux depending on mounting height and reflectance. It is equally appropriate for large retail stockrooms, vehicle workshops and covered loading bays.

What the specifications mean in practice

• 150 lm/W: Every watt consumed produces 150 lumens of usable light, meaning you achieve the same brightness as a 400W metal halide fitting at less than half the wattage.
• 22,500 lm: This total output is sufficient to meet 300 lux across roughly 35 m² at a 7-metre mounting height, reducing the number of fittings required in a grid layout.
• 4000K: Neutral white light closely resembles natural daylight, keeping the space bright and alert-feeling without the cold harshness of 5000K or the warmth of 3000K.
• 90° beam angle: A tighter beam than the typical 120° floods the working plane directly below, minimising wasted light on walls and improving vertical-surface uniformity in racking aisles.
• DALI dimmable: Full DALI protocol compatibility means the fitting can be addressed individually or in groups within any standard DALI-2 building management or lighting control system.

Installation and compatibility

The UFO high bay ships with a 0.3 m cable and a standard suspension hook for hook or cable mounting. Power selection (100W, 120W or 150W) is set at commissioning via the driver. DALI wiring connects to your existing two-wire control bus. Clightstore provides a free DIALux light study to confirm mounting height, spacing and expected lux levels before you order.
