G9 and G4 Capsule Light Bulbs
LED capsule bulbs and halogen capsule bulbs are ideal for the smallest of light fittings and are commonly used in cooker hoods, under cabinet lighting and integrated light fittings. They are very compact but offer a bright light for their size. There are two types of capsule bulbs: G9 bulbs and G4 bulbs. The biggest difference between the two capsules are their voltages. Our range of G9 light bulbs operate off the mains voltage (220-240V), while G4 capsule bulbs are low voltage (usually between 12V and 24V) and need to be installed with a compatible transformer to transform mains voltage into a lower one suitable for the bulb.
