Sylvania Energy Saving Halogen G4 Capsules


Sylvania Energy Saving Halogen G4 Capsules use xenon gas rather than argon to achieve a 20% energy saving over regular halogen capsules. They are available in a choice of 8W (equivalent 10W) or 16W (equivalent 20W) versions and offer the usual 2,000 hour halogen lifespan.

These small 12V capsules are typically used in confined-space applications such as electrical appliances, boat lighting, shop windows and wardrobe lighting. In keeping with other filament lamps they are fully dimmable and have a warm white 2800K output with exceptional colour rendering. Unlike some other technologies, halogen light output remains constant throughout the lifespan of the lamp.

Connection of the Sylvania Energy Saving Halogen G4 Capsule is through a standard G4 bi-pin cap. A separate low-voltage transformer is required for operation, which is often integrated into the light fitting (low voltage transformers are also available separately from Lyco).


The dimensions of the Sylvania Energy Saving Halogen G4 Capsule are:

  • Length: 44mm
  • Width: 9mm
