Philips SDW White SON
Philips produces gas discharge lamps of a level of quality that you can expect from Philips. The Philips MASTER SDW lamps give an extra warm white light with an excellent color rendering. SDW gas discharge lamps have a long average lifespan between 10.000 and 15.000 hours. The high efficiency of the MASTER SDW lamps results in lower energy costs and also less waste heat. You can use the SDW gas discharge lamp in shops to, for example, create a cosy atmosphere in a furniture shop.
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.
