Compatibility and installation

Direct replacement for halogen

This LED lamp is designed to replace an old 50W GU10 halogen lamp. The base is the same GU10, and the dimensions fit standard halogen luminaires. Replacement is simple — remove the old halogen, install the LED in its place without changes to wiring or luminaire.

Energy saving

4.2 W power replaces a 50 W halogen — energy saving is approximately 92%. The lifespan of 15,000 hours is about 7 times that of halogen (2000 h), so lamp replacement work is also significantly reduced.

Wide 110° beam angle

A standard GU10 halogen lamp usually has a beam angle of 36–60° (for spot lighting). This LED lamp has a beam angle of 110°, which means wider general light. It is well suited for general lighting but not for places requiring precise spot lighting. For spot lighting, choose a separate 36° beam angle LED lamp (e.g. Sylvania RefLED Superia Retro 36°).

Not dimmable

This is a non-dimmable LED lamp — do not connect it to a dimmer. If connected to a dimmer, the lamp may flicker or be damaged.

Color temperature selection

  • 3000K (warm white): cozy, relaxing — suitable for homes and living areas
  • 4000K (neutral white): clear, supportive for work — suitable for offices and kitchens
  • 6500K (cool white): bright, energetic — suitable for warehouses and workspaces
Power: 4000K

Usein kysytyt kysymykset

Does this LED bulb replace an old 50W GU10 halogen bulb?

Yes. This LED bulb is designed as a direct replacement for a 50W GU10 halogen bulb. The base is the same GU10, the dimensions (Ø 50 mm × 54 mm) comply with the halogen bulb standard, and the light output matches the former halogen.

You can install the LED directly into the same fixture as the old halogen without any modifications. Energy savings are typically over 80% compared to halogen, and the LED bulb's lifespan (15,000 hours) is many times longer than that of a halogen.

What color temperature options are available?

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

  • 3000K: warm white — cozy and relaxing, suitable for homes
  • 4000K: neutral white — clear and supportive for work, suitable for offices
  • 6500K: cool white — bright and energetic, suitable for warehouses and workspaces

Choose the colour temperature via the variant option during the order process. 3000K is recommended for most households.

Is this lamp dimmable?

No. This is a non-dimmable LED lamp—do not connect it to a dimmer.

When connected to a dimmer, a non-dimmable LED may flicker, fail to operate, or be damaged. If you require a dimmable GU10 lamp, look for a model marked "DIM" separately in our products—e.g., Sylvania's dimmable RefLED Retro series lamps.

How do the Sylvania series differ from each other?

  • RefLED ES50 (standard): basic quality, CRI 80, 15,000 h lifespan, 3-year warranty

  • RefLED Superia Retro: premium quality, CRI 90, COOLFIT technology to prevent overheating, 5-year warranty
