Saxby 78857 GU10 LED Lamp 5W 4000K
470 Lumen GU10 LED Lamp with Wide 120° Beam Angle
The Saxby 78857 GU10 LED Lamp 5W 4000K provides a bright 470 lumen output while using just 5W of power. Designed with SMD LED technology and a particularly wide 120° beam angle, this lamp produces broad, even illumination for suitable domestic and commercial lighting applications.
With a 4000K colour temperature, the lamp provides a clear neutral white light. Its matt white thermoplastic body and frosted polycarbonate finish create a clean appearance while helping diffuse the light across the wide beam.
Efficient 5W Performance with 470 Lumens
The current Saxby 78857 specification delivers 470 lumens from a 5W LED lamp, giving an efficacy of 94 lumens per watt. This provides strong light output with low power consumption and makes the lamp a practical option where a non-dimmable GU10 LED with a broad beam is required.
The Saxby 78857 GU10 LED Lamp 5W 4000K is also flicker free and has a rated lifetime of 25,000 hours.
