includes VAT 25.5% Shipping costs are calculated at checkout.
Sylvania Retro DIM is a premium-level LED lamp for the GU10 base. With 3.7 W of power, the lamp produces 345–360 lm of light and replaces a traditional 50 W halogen lamp. The CRI 90 color rendering provides natural light, and the 25,000-hour lifespan ensures long durability. Dimmable — you can connect it to an LED-compatible dimmer. The 36° beam angle makes this an excellent choice for spotlighting.
GU10 base. 230 V mains voltage. Dimmable (LED-compatible dimmer). 36° beam angle — spotlight, not a wide general light.

Compatibility and installation
Premium quality — CRI 90
The Sylvania Retro DIM series belongs to Sylvania's premium collection. CRI 90 is significantly better than the basic series' CRI 80 — colors are rendered more naturally, and especially red and skin tones look more pleasant. This is well-suited for retail, exhibition, and home use where color accuracy is important.
Long lifespan — 25,000 hours
The 25,000-hour lifespan is clearly longer than Sylvania's basic series (15,000 h). This means less frequent need for replacement and lower maintenance costs — especially in locations where changing the lamp is difficult. The manufacturer provides a 5-year warranty.
Direct replacement for 50W halogen
The dimensions (Ø 50 × 54 mm) and base (GU10) conform to the halogen standard, so the lamp fits directly in place of an old halogen without any changes.
36° beam angle — spotlight
36° is a typical GU10 spotlight angle. Suitable for, for example, lighting artwork, shelves, or worktops. If you need a wider general light, choose a lamp with a 110° beam angle (e.g., RefLED ES50 6.2W).
Dimming
This is a dimmable LED lamp. Use an LED-compatible dimmer for the best results — old halogen dimmers may work, but can cause flickering or a limited adjustment range.
Choosing color temperature
- 2700K (warm): very warm white — incandescent-like atmosphere
- 3000K (warm white): cozy and relaxing
- 4000K (neutral white): clear and supportive of work
- 6500K (cool white): bright and energetic
