includes VAT 25.5% Shipping costs are calculated at checkout.
This is a traditional MR11 halogen spotlight lamp, used to replace broken MR11 halogens in luminaires. Featuring 12 V halogen technology, 20 W power, and a 30° beam angle—it's suitable for older MR11 luminaires where LED alternatives don't work (e.g., compatibility issues with transformers or dimmers). The 2800 K colour temperature produces a warm and familiar halogen tone.
12 V halogen—requires a 12V transformer. GU4 base (MR11). The lifespan is typical for halogen (approx. 2000 h), significantly shorter than LEDs.

Compatibility and installation
When to stick with halogen?
MR11 LED alternatives are available, but compatibility issues are common—especially with old halogen transformers and dimmers, LEDs can flicker or fail to light up. Halogen lamps always work with these components, making them a safe choice as a replacement when you don't want to modify an existing luminaire.
12 V — transformer required
MR11 always operates at 12 V voltage and never directly on 230 V mains voltage. Most MR11 luminaires already have a built-in transformer. If you are building your own lighting setup, check our selection in the transformers category.
GU4 base — two pins
GU4 is a two-pin base with a pin spacing of 4 mm. This is the standard base for MR11 lamps. Check the luminaire before purchasing to ensure GU4 is the correct base—larger spotlights often use GU5.3 (MR16 version) or GU10 (direct 230 V).
MR11 vs MR16
- MR11 (this, Ø 35 mm): smaller, suitable for compact luminaires (display cases, furniture lighting, small spotlights)
- MR16 (Ø 50 mm): larger, more common, suitable for most recesses and spotlights
Check the luminaire dimensions before purchasing.
Beam angle 30°
30° is a narrow spotlight beam angle that precisely concentrates light on a defined area. Especially suitable for accentuating artwork, objects, or work surfaces.
Lifespan — typical for halogen
The lifespan of a halogen lamp is typically 2000 hours—significantly shorter than an LED lamp (25,000+ h). Be prepared for replacements and consider an LED switch if the luminaire and transformer allow it.
Installation checklist
- Turn off the power at the main switch
- Allow the old lamp to cool completely
- Do not touch the bulb with bare hands—finger grease damages the glass
- Use a clean cloth or glove
- Install the new lamp—two pins into the slots
- Turn on the power and test
