Classic Warmth and Seamless Dimming

Halogen bulbs are renowned for their excellent color rendering and cozy, warm light. These 20W G4 bulbs from G Master are no exception. They are perfect for ambient lighting in living rooms, display cabinets, or under kitchen shelves. Because they are fully dimmable, you can easily adjust the light intensity to match any mood, provided your fixture supports dimming.

Consider Energy Consumption and Heat

While the purchase price of this set is highly attractive, it is important to keep the characteristics of halogen technology in mind. Consuming 20 watts per bulb, they are significantly less efficient than LEDs. Additionally, these bulbs get very hot during use. When installing them, make sure not to touch them with bare hands, as skin oils can shorten the lifespan of the quartz glass.

Frequently asked questions

Do I need a transformer for these bulbs?

Yes, these G4 halogen bulbs operate on 12 Volts (low voltage). You will need a compatible 12V transformer to connect them to standard mains power (230V).

Can I touch the bulbs with my bare hands during installation?

It is highly discouraged to touch halogen bulbs with bare hands. The oils from your skin can burn into the quartz glass, causing the bulb to fail prematurely. Always use a clean cloth or tissue.

Are these bulbs suitable for cooker hoods?

Yes, provided your cooker hood has a G4 fitting compatible with 12V and 20W bulbs. Due to their heat resistance, they are frequently used in these appliances.
