Halogen heater lamps are for catering applications and are commonly used in restaurants, brasseries and cafe\'s to keep prepared food warm before serving. As with all linear halogen lamps, while installing the lamp it\'s important not to touch the glass part of the lamp with bare skin as the natural oils from your skin can cause the lamp to fail prematurely. If you do touch the lamp, then you should use alcohol to remove the oils from the glass. General Characteristics: Wattage [W]: 1300w Voltage [V]: 240v Shade: Ruby Length: 254mm
