G4 LED Bulbs

G4 bulbs are compact capsule-shaped lamps whose pins are 4mm apart. These bulbs work on 12V so can’t be connected directly to the mains. Therefore you will need a transformer. Replacing your old halogen bulbs with LED G4 lighting is easy with the bi-pin socket. Due to its compact dimensions, the G4 bulbs easily fit into the smallest luminaires. By switching to LED, you save on energy costs, but retain the desired light quality. In addition, you do not have to replace the lamps for years, as they last up to 20 times longer. Always take a look at the size of the LED bulb, since it may differ slightly from the halogen variant.

Extra warm white (2,700 Kelvin): LEDs with an extra warm white light color have a high proportion of red, which has a particularly pleasant effect on the lighting mood. Extra warm white G4 LED bulbs fit particularly well in living areas such as the bedroom but also in hotel rooms, bars and restaurants. 

 

Warm white (3,000 Kelvin): G4 LED Bulbs with a warm white light color can basically be used anywhere can be used. This color temperature is cozy and inviting. We therefore recommend them especially for the living room and hallway. But warm white G4 LEDs can also be used in trade, for example in the entrance area of hotels and restaurants or in retail.

 

Cold white (4,000 Kelvin): The cold white light color creates a neutral atmosphere and strengthens concentration and eyesight. This is why G4 pin-base bulbs are often used in the kitchen (for example as under-cabinet lights).

 

What is the difference between G4 and GU4 sockets?

Light sources with a G4 or GU4 socket have a pin spacing of 4 mm. The only difference between the two sockets is the diameter of the socket pins. This is between 0.95 mm and 1.05 mm for GU4 bulbs and between 0.65 mm and 0.75 mm for G4 bulbs.
