Osram MR11 Spotlight LED Light Bulb Dimmable GU4 3.2W (20W Eqv) Warm White

  • Cap type: GU4
  • Power Consumption: 3.2W
  • Equivalent: 20W Halogen MR11
  • Colour Output: Warm White
  • Dimensions: Diameter=35mm Height=38mm

This low voltage MR11 from Osram is designed to be a high-quality, professional LED replacement for older 20W halogen bulbs. It offers a bright 184 lumens of warm white light, and its focused 36° beam angle makes it ideal for museums, galleries, shop windows and display cabinets. It is also dimmable, giving you even more control over your lighting setup.

The LED spotlight offers all the brightness of the halogen bulbs it replaces, but uses only a fraction of the energy. With a superior lifespan of 25,000 hours, it will be years before this bulb needs replacing again.

The two-pin GU4 base also retrofits to existing light fixtures, making it easy to swap out your old bulbs. Please note, as this is a low voltage bulb (12V), it needs to be fitted with a compatible low voltage driver/transformer when installed on a mains circuit. Please see the manufacturer's website for more details.

Please note that theis light bulb will operate with most AC and DC 12V transformers. However, some 12V transformers may have a minimum required load which may not be met when installing low powered LEDs: these drivers may cause flickering or the LEDs not to function correctly. If this issue arises it may be necessary to source a suitable LED driver. Please refer to the manufacturers website for compatibility.

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).
