IR500W216SK15-REF is an Infrared Lamp made of quartz 10mm diameter. They convert virtually all the electrical power into heat, no energy is wasted and can be switched on/off instantly so heat is given instantly. These lamps are suitable for universal orientations so will suit most installation positions. Even though they are easy to install and replace, care must be taken not to touch the tube with bare hands and that the ends sits correctly in the holder. Clear infrared lamps are used for heating and are used in many process heating applications that require instant shortwave drying. Other applications are heated counters in restaurants and cafe.
