Surfaced lighting spot Synergy21 S21-LED-UFO0036, LED 240 W, 4500 K, 31 000 lm, IP65, 90–305 V, round, black

Synergy21 S21-LED-UFO0036 is a surfaced round LED spotlight designed for high-output general and accent illumination. With a rated power of 240 W and luminous flux up to 31,000 lm at a neutral-white 4500 K colour temperature, this black round fixture supports a wide supply voltage range of 90–305 V and an IP65 rating suitable for outdoor or damp locations. The design targets industrial, commercial and architectural applications that require robust, weather-resistant lighting with sustained lumen performance.

Advantages

The spotlight combines high luminous efficacy and a broad input-voltage tolerance to ensure stable operation in varied electrical environments. IP65 protection provides resistance to dust ingress and water jets, enabling safe use outdoors or in washdown and humid conditions. A CRI of approximately 80 offers acceptable colour rendering for general-purpose tasks, while the 4500 K colour temperature balances neutral white illumination with visual clarity. The round, low-profile housing in black supports straightforward installation and integration into existing structures.

Suitable for

• Warehouse and logistics halls requiring high lumen output
• Industrial production areas and workshops
• Commercial spaces such as retail floors and shopping centres
• Large-area architectural façades and outdoor signage
• Parking lots, loading bays and service yards

• Form factor: round, surfaced-mounted housing in black

How to use

Install the spotlight on a suitable solid surface following local electrical codes and safety regulations. Ensure mains power is switched off before connecting the fixture to the supply. The unit accepts 90–305 V AC; connect live, neutral and earth conductors according to the wiring diagram supplied with the product. Mount the round housing securely with appropriate fixings for the surface material and environmental conditions. After connection, restore power and verify correct operation and beam direction. For outdoor installations, ensure all cable entries and junctions maintain IP65-level sealing.

Usage recommendations

For optimal lifetime and consistent lumen output, avoid continuous thermal obstruction around the fixture—provide sufficient clearance for heat dissipation. Use with compatible surge protection in locations prone to voltage fluctuations. Clean external surfaces periodically with a damp cloth and avoid high-pressure cleaners directly on electrical connections even though the fixture body is IP65 rated. Where colour rendering is critical, consider complementary fixtures with higher CRI for task-specific areas.
