Philips CDM-SA

A halogen lamp, like the Philips CDM-SA, is basically an incandescent lamp which has a small amount of halogen gas inside. When this gas burns, the lamp produces light. This technology means that halogen lamps are significantly more energy efficient than incandescent lamps, with a high luminous efficiency and a warm colour temperature. Halogen lamps are especially perfect for colour critical areas such as retail, directional lighting in hospitality and offices.
