This energy efficient LED MR11 spotlight light bulb is a high-quality, professional replacement for outdated 20W halogen spotlights, offering the same brightness, but using only a fraction of the energy.

The light bulb emits a bright 184 lumens of warm white light, with a narrow 36° beam angle that's perfect for highlighting products in retail displays, or in galleries and other display lighting. It is also dimmable, giving you even more control over your lighting.

The light bulb's long 25,000 hour lifespan means that once installed, it will not need replacing again for years. It also retrofits to existing light fixtures, so installing it is simply a case of swapping out the old light bulb for the new.

As this is a low voltage light bulb, it will need to be fitted with a compatible driver or transformer when installed on mains circuits. See the manufacturer's website for more information.


This LED MR11 spotlight lamp is fitted with a low voltage 12V GU4 2-pin (4mm apart) base.

Please visit the manufacturer's website for up-to-date dimmer switch compatibility lists for this Osram LED MR11 Spotlight light bulb before purchase.

Here at LightBulbs Direct, we want you to be able to buy with confidence both in ourselves and the products we sell. With this in mind, a number of our bulbs carry a specific warranty that ensures you can do exactly that.

Any LED or LED Smart light bulb bought from Lightbulbs Direct carries a 24-month warranty.

If you should purchase an LED light bulb from LightBulbs Direct and have it fail, break or develop a fault at any point within the timeline stated above from the date of purchase, we will happily replace the item or offer a full refund, depending on your wishes.

In instances where large numbers of bulbs fail within a relatively short period of time, we may ask you to return them to us so that they can undergo testing to identify any potential issues.

What doesn't our warranty cover?

In any instance where your bulb has developed a fault, we will do our utmost to replace it or offer a full refund (provided the item is still within its stated warranty period). However, if it becomes apparent that the product has been misused, tampered with or modified in any way, we will view this as having voided its warranty.

'Misuse" includes, but is not limited to, incorrect operation by the user, use of non-dimmable bulbs on a dimmable circuit or connection to or operation with an unsuitable power supply. 'Tampering' or 'modification' can be interpreted as any activity designed to alter the product in such a way that it can be used in a manner that wasn't intended by its original design. This can include rewiring, removing plugs, home repairs or changing components. Unfortunately, we won't be able to replace any item that has undergone any such process.

If you have any further questions about our Warranty or Returns Policy that aren't addressed on this page, please feel free to contact us.
