The Sylvania Retro DIM is a premium-level LED lamp for GU10 sockets. With a power of 3.7 W, the lamp produces 345–360 lm of light and replaces a traditional 50 W halogen lamp. The CRI 90 color rendering offers natural light, and a lifespan of 25,000 hours ensures long durability. Dimmable — you can connect it to an LED-compatible dimmer. A beam angle of 36° makes this an excellent choice for accent lighting.

GU10 base. 230 V mains voltage. Dimmable (LED-compatible dimmer). Beam angle 36° — spotlight, not wide general lighting.

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 pleasing. 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 significantly longer than Sylvania's basic series (15,000 h). This means less frequent replacement and lower maintenance costs — especially in locations where lamp replacement is difficult. The manufacturer provides a 5-year warranty.

Direct replacement for 50W halogen

The dimensions (Ø 50 × 54 mm) and base (GU10) comply with the halogen standard, so the lamp fits directly in place of an old halogen without modifications.

Beam angle 36° — spotlight

36° is a typical GU10 spotlight angle. Suitable for lighting artworks, shelves, or work surfaces, for example. If you need wider general lighting, 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.

Color temperature selection

  • 2700K (warm): very warm white — incandescent-like ambiance
  • 3000K (warm white): cozy and relaxing
  • 4000K (neutral white): clear and supportive for working
  • 6500K (cool white): bright and energetic
Power: 3000K

Usein kysytyt kysymykset

What is the advantage of the Sylvania Retro DIM series compared to the basic RefLED ES50 series?

The Sylvania Retro DIM is a premium range that differs from the basic range in several ways:

  • Colour rendering index CRI 90 vs 80 in the basic range — more natural colour rendering, especially red and skin tones
  • Lifespan 25,000 hours vs 15,000 hours in the basic range
  • 5-year warranty vs 3 years in the basic range

The premium range is particularly suitable for spaces where colour accuracy is important (shops, exhibitions, atmospheric home lighting) or where changing bulbs is difficult.

What color temperature options are available?

This lamp is available in the following color temperatures: 2700K/3000K/4000K/6500K.

  • 2700K (warm): very warm white — incandescent-like atmosphere
  • 3000K (warm white): cozy and relaxing
  • 4000K (neutral white): clear and supportive for working
  • 6500K (cool white): bright and energetic

Choose the color temperature during the order process via the variant selection. Thanks to the high color rendering (CRI 90), colors appear more natural in this premium series than in the basic series lamps.

Is this lamp dimmable?

Yes. This bulb is dimmable—you can connect it to an LED-compatible dimmer and adjust the light brightness.

Ensure that the dimmer you are using is designed for an LED load. Older halogen dimmers may work with LED bulbs, but the result is not always optimal—the bulb may flicker or the dimming range may be limited. An LED-compatible dimmer provides a smoother result.

What is the best use for a 36° beam angle GU10 bulb?

A 36° beam angle is a typical GU10 spotlight angle — significantly narrower than the basic series' 110°. It is especially suitable for accent lighting:

  • Artworks — paintings, photos on the wall
  • Shelves and display cases — focused light on products or objects
  • Work surfaces — kitchen countertop, desk
  • Retail lighting — highlighting products

If you need a wider general light (corridors, hallways, general warehouse lighting), choose a lamp with a 110° beam angle (e.g., RefLED ES50 basic series).
