Osram Halogen GU10 Mains Voltage Light Bulb Guide
Widely found in downlighters and spotlights, especially in kitchens, the Osram GU10 Halopar halogen light bulb is one of the most widely sold light bulbs in the world. With over 100 years manufacturing lighting products, Osram are the market leading producers of high quality halogen light bulbs.
The Osram GU10 Halopar halogen light bulb fits into mains voltage light fittings. This is in contrast to MR16 halogen light bulbs which work from 12V and use a transformer. They are approximately the same diameter as 50 pence piece, so are sometimes known as 50p light bulbs.
Characterised by two thick metal posts with "shoulders", the Osram GU10 halogen light bulb twists and locks into place. For this reason, some other brands of GU10 are known as twist and lock GU10 mains voltage light bulbs. This makes GU10 light bulbs easy to fit. It is impossible to fit a low voltage MR16 bulb into a mains voltage GU10 fitting and vice-versa.
Osram GU10 Halopar Halogen Light Bulbs
The standard range of Osram halogen light bulbs are dichroic. These are sold on our site as Osram Halopar 16 halogen light bulbs. Relatively inefficient compared to other, more advanced halogen light bulbs, these are cheaper and suitable for limited budgets or in applications where the light bulbs do not get much use. The Osram Halopar 16 range of light bulbs can also be fully dimmed.
