Our Sylvania range of HID (high intensity discharge) metal halide lamps contain a ceramic arc tube to ensure improved colour stability, better lumen output and an improved lifetime. The Sylvania Superia range of HID lamps offer excellent colour rendering and high luminous efficiency in a compact size, making them ideal for a vast variety of lighting applications both interior and exterior. This range contains a UV-filter to protect objects within the light beam from discoloration and fading, and are therefore perfectly suited for use in shops, hotel lobbies and retail environments. The Sylvania MetalArc range produces bright white light at high light outputs, meaning that you can achieve the high light levels you require without needing additional lighting fixtures.
The colour temperature refers to the colour produced by a light. It's measured in Kelvin (K) and ranges from warm white (1700K - 3000K) to daylight white (6500K). Neutral white (3100K - 5000K) is mainly used for general lighting applications.

Cap / Base
The cap/base of a bulb is the part that connects it to the socket in the fixture. In Ireland, B22 (Bayonet) caps/bases are still the most popular, although E27 (Edison screw) caps/bases are becoming increasingly popular. GU10 is the most common cap/base for spotlights. Check which cap/base you need carefully as many other types are also available.
The colour code is a combination of the colour rendering index (CRI) and the colour temperature (K). The first number refers to the CRI (1 = very poor colour rendering, 9 = maximum accuracy). The second and third numbers refer to the colour temperature. For example, a light with a colour code of 830 has very good colour rendering and produces a warm white light.
