What is a GU10 LED?

What is a GU10 LED?

Thanks to its compact design, GU10 is a very popular illuminant system and can be used particularly flexibly. Before we get to further details and dig deeper into the matter, we first clarify what the term GU10 stands for:

  • G describes the fastening system
  • U means “universal” because the GU10 e.g. also fit in GX10 sockets
  • 10 is the distance in millimeters of the bipolar pins (center-center)

Abbreviations for common lamp base systems:

  • B: bayonet base (e.g. B15, B22)
  • E: Edison thread / screw thread (e.g. E27, E14)
  • F: Single pin base with conductive outer sleeve (e.g. MF / T 3/4, MF T1 3/4)
  • G: bi-pin / multi-pin socket (e.g. GU5.3, GU10)

Dimensions of a GU10-LED

GU10 lamps are manufactured in different diameters (often 50mm) and heights, only the connecting pins at the lower end always have the same dimensions: the bayonet pins at the lower end have a diameter of 5mm, a total height of approx. 6mm and are in a distance of 10mm (center to center) built into the lamp.

What operating voltage do GU10 LED lamps need?

Like the halogen counterparts, GU10 lamps are operated directly on the 230-240 volt AC network and, unlike the MR16 GU5.3 design, do not require a 12/24 volt transformer. The advantage of high-voltage technology is the simple retrofitting of existing systems without the installation of additional technology as with MR16 LEDs. A disadvantage is the higher heat development in the housing due to the integrated power supply.

In which areas can GU10 LED lamps be used?

GU10 LED lamps are most commonly used in the following areas:

  • Living Room
  • Kitchens
  • Bathroom
  • Bedroom
  • Retail/Showrooms
  • Hotels/Restaurants

Are GU10 LEDs dimmable?

In general, all GU10 LEDs from well.e.d. dimmable and the best part is that they can be used with most third party dimmer switches. However, for optimal performance, we recommend using dimmer switches tested with our lamps, which are also available in our shop.

What is the “Dim-To-Warm” function?

With the addition “Dim-To-Warm” our lamps are identified, which do not (only) become darker when dimmed down, but behave like a halogen lamp and emit a warmer light. At full power, for example, our LED WL7CCT brings a light temperature of 3000 Kelvin, dimmed down to a warm 1800 Kelvin. Dim-To-Warm-LED is particularly well suited for decorative lighting, as is often required in living rooms, restaurants, hotels or cruise cabins. It is perfect for rooms and situations where you want dimmed and warm light.

Which beam angle should I choose for a GU10 LED?

The beam angle is measured in degrees. A larger beam angle covers more space with light. As with the color variant, the choice of beam angle is entirely up to you. As a guideline, we recommend using larger beam angles in living rooms where many people gather. On the other hand, narrow beam angles are often used for decorative purposes or areas in which you want to illuminate a more defined area, e.g. on work surfaces in the kitchen.

How much does a GU10 LED cost?

The market is currently dominated by particularly cheap LEDs in the price range of € 2.00 to € 8.00 per LED. In the high-end range, however, the prices per GU10 lamp are between € 30.00 and € 50.00. This large price difference is due to the use of different individual components, resulting in different durability and light quality. well.e.d. are composed of particularly high-quality individual components, resulting in high color rendering values ​​of CRI>98, a low blue light indicator for optimal light quality in all situations.
