Our G4 LED bulbs and halogen capsule light bulbs collection brings together compact lamps designed for low voltage fittings where space is limited but reliable light is essential. You will find both modern LED G4 bulbs and traditional halogen capsules, making it easy to match existing fittings or upgrade selected lights without changing the whole setup.

This range is suitable for homeowners, landlords and trade installers who need dependable G4 capsule bulbs for everyday lighting tasks. From replacing a single lamp in a cabinet light to stocking up for multiple fittings across a property, these small bi-pin bulbs are commonly chosen for their versatility and familiar format.

G4 bulbs are typically used in kitchens, display cabinets, under-cupboard lighting, caravans and boats, as well as decorative fittings where a discreet light source is required. Both LED and halogen options can be found here, helping you maintain a consistent look across rooms while choosing the technology that suits your project.

When choosing a G4 light bulb, it is important to check whether your fitting is designed for LED or halogen, as well as confirming the correct low voltage supply. Consider the light colour if you are matching existing lamps, and check physical dimensions to ensure the capsule fits comfortably within the fixture.

Our collection focuses on compatible G4 capsule styles that are widely used in UK installations. Product pages provide clear specifications to help you select the right option for your fitting. If you are replacing older halogen capsules, LED alternatives may also be worth considering where suitable for the existing setup.
