The all new 4.5W Parathom Advanced PAR16 50 retrofit LED GU10 spotlight light bulb from Osram delivers a warm white accent beam that is comparable to that of a 50W halogen light bulb.
It is compatible with a wide range of dimmer switches and delivers huge energy savings without any compromise on brightness or quality. It lasts an incredible 25,000 hours and comes with a 5 year warranty from Osram.
It sports 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 Osram and supersedes their old GU10 Spotlight part codes: AC33736.
Please visit the manufacturer's website for up-to-date dimmer switch compatibility lists for this Osram LED GU10 Spotlight light bulb before purchase.
