Osram's bestselling GU10 lamp

For spotlighting heat-sensitive products – and for general spotlighting, display cabinets and exhibition areas – Osram’s bestselling GU10 retrofit lamp is the Parathom Par 16 50 36° ADV. The lamp comes in three flavours of white: 2700, 3000 and 4000K. It is also dimmable, has an expected life of 25,000 hours and a five-year guarantee. Energy consumption is 5.3W and Osram says the lamp is less likely to be incompatible than traditional low-voltage MR16s.
