LED bulb SUPERSTAR MR11 12 V 2.8W 927 GU4 4058075433083

Replaces a 20 W halogen bulb but consumes only 2.8 W

This is not just a light source replacement — it’s a shift in how you think about lighting. The LED MR11 bulb with GU4 base operates at 12 V, making it perfectly compatible with existing transformers and reflector fixtures. Instead of a 20 W halogen that generates excessive heat and wears out quickly, you get warm, stable light at 2700 K — the same cozy glow as your old halogen, but without the overheating and the need to replace it every six months.

Works with any dimmer — if that dimmer works

Not all dimmers are created equal. This bulb is labeled as dimmable — and indeed, it operates smoothly with most modern electronic transformers and leading/trailing edge dimmers. However, if you’re using an old magnetic transformer or a low-quality dimmer, flickering may occur. This doesn’t mean the bulb is faulty — it’s a compatibility issue with the circuit. In practice: if your previous halogen dimmed quietly, this LED should too.

Lasts 25 000 hours — because there’s no filament to burn out

No filament to break. No gases to leak. It’s a diode — simple, robust, and resistant to vibrations and frequent switching. Under household conditions (25°C), after 25 000 hours of operation, it will still emit at least 90% of its initial luminous flux. This isn’t marketing — it’s verified L90/B10 performance. With average usage (3 hours per day), it will last over 20 years.

So: halogen-like light, without halogen’s drawbacks

• Warm white light — not cold, not blue. Ideal for kitchens, living rooms, bathrooms, or hotel rooms.
• High color rendering — colors of objects and walls are rendered almost as accurately as under natural sunlight. No muted or dull tones.
• Focused beam — not scattered like in AR111 lamps. Precise accent lighting for artwork, shelves, or kitchen countertops.
• Standard dimensions — fits any MR11 fixture without modification.
• Indoor use only — do not install on balconies or in unprotected bathrooms.
• Compliant with safety standards — meets CE / UKCA / EAC requirements for European and Eastern European markets.

A 4-year warranty? This isn’t just a “bonus.” It’s proof the manufacturer has full confidence in the bulb’s durability. The installer knows: if something fails after a year, it’s not an installation error. The customer knows: they won’t need to replace it again in two years.
