Halogen G4 light bulbs are push fit which means they push directly into the fixture without any fuss. Halogen G4’s are low voltage 12 volt capsules which operate normally with a mains voltage lighting fixture with integral 12 volt mains transformers. The G4 capsules are also available in miniature which are used in high quality miniature light fixtures within small spot lamps for shelf lighting.
Saving-Light-Bulbs supplies halogen G4 capsules in 5W, 10W and 20W. These are the standard wattages that the capsules can be expected to come in because of their size and purpose. All the capsules, despite their different wattages come in a warm white colour temperature. The warm white colour temperature is ideal for interior use and is universally used for a variety of different purposes. Halogen G4 capsules are expected to have a life of 1000 hours.
