This 8.3W Performance Class PAR16 retrofit LED GU10 spotlight light bulb from Ledvance delivers a cool white accent beam that is comparable to that of a 80W halogen light bulb.

They are compatible with a wide range of dimmer switches and deliver huge energy savings without any compromise on brightness or quality. They last an incredible 15,000 hours and come with a 5 year warranty from Ledvance.

They sport the same glass body you'd expect to see on a traditional halogen GU10, lending it a familiar aesthetic that's reminiscent of the very light bulbs it's been designed to replace. This results in an LED light bulb that manages to reduce your lighting bill by up to 90% when compared with traditional halogen spotlights, but doesn't look any different.

This spotlight lamp is traditionally known as a PAR16 with a GU10 2-pin twist and lock (10mm apart) base.

This GU10 Spotlight is a newer product from Ledvance and supersedes their old GU10 Spotlight part codes: 4058075609099.
