Meet the Crompton Lamps cool white fully dimmable LED GU10 spotlight bulb, a bright, energy-saving replacement for traditional halogen GU10 lamps.
Delivering over 450 lumens, it matches the light output of a 50W halogen GU10 while using only 5W, making it ideal for retrofit use in homes and commercial interiors.
It features the popular PAR16 spotlight design with a GU10 two-pin twist-and-lock cap (10 mm spacing), plus a durable aluminium heat sink and thermal plastic body.
Advanced COB (chip-on-board) LED technology provides instant full brightness with a 4000K cool white colour temperature and a 45° beam angle for focused illumination.
This dimmable GU10 uses DuoDim™ technology for compatibility with both leading-edge and trailing-edge dimmers, and it is suitable for use in fire-rated downlights.
Built for dependable, long-term performance, this lamp is made to last and helps cut down the hassle and cost of frequent replacements. With an impressive 30,000 hours rated life and up to 15,000 switching cycles, it stays reliable even in busy spaces where lights are turned on and off often.
It also delivers good colour accuracy with a CRI of 80 or higher, making colours look natural and clear. Recommended for indoor use, it’s backed by a reassuring 4 Years warranty.
This GU10 Spotlight is a newer product from Crompton Lamps and supersedes their old GU10 Spotlight part codes: LEDGU105CWSMD-DIM.
