The 1129 lamp is suitable for commercial lighting applications, as well as under-shelf lighting for retailers and hospitality businesses. With its long life, energy efficiency and powerful light output, it is an ideal choice for businesses who want a long-term investment in their lighting. The 1129 lamp is available in two types: the incandescent version and the neon-filled version, both providing excellent light quality and output.

The incandescent version of the 1129 lamp is handmade using specially processed incandescent tungsten filament, embedded in a fused quartz envelope and hermetically sealed. The quartz envelope is designed to contain and protect the filament, while the special vacuum ensures that the filament is unaffected by oxygen. This ensures that the filament has an extremely long lifespan and can last for many years. The light output of an incandescent 1129 lamp is typically very strong and emits a warm, yellowish hue.

The neon-filled version of the 1129 lamp is made by filling the quartz envelope with a noble gas, such as argon or neon. This gas is then ionised by the electrodes, creating a plasma discharge inside the lamp. The gas that is used to fill the lamp can be varied in order to create different colour temperatures, from cool to warm. The light output of a neon-filled 1129 lamp is typically white and very bright, with a good colour rendering index.

The main advantage of both of these lamps is their long life, with an incandescent model typically lasting up to 15,000 hours and a neon-filled model typically lasting up to 25,000 hours. This makes them very energy-efficient, requiring fewer replacements over time, meaning they are less costly to maintain. Both types of lamp also offer excellent brightness and colour rendering.

The 1129 lamp is a popular choice for many businesses, especially in commercial lighting applications. Its long lifespan and energy efficiency make it an ideal choice for businesses who wish to make a long-term investment in their lighting. Due to its powerful light output, it is also well-suited to under-shelf lighting in retail outlets and hospitality businesses.
