Single Tube Short Wave Infrared Heater LampsHalogen lamps are incandescent lamps filled with highly pressurized halogen gas. This gas is combined with a small amount of bromine or iodine which causes tungsten atoms to regenerate by lessening the evaporation of the filament. This leads to a much longer life of halogen lamps than incandescent lamps. Due to the high pressure and temperature halogen lamps produce, they are relatively small and made out of quartz glass because it has a hotter melting point than standard glass. Product nameShort Wave IR LampTube diameter10/11/12mmTotal length/Heated length626mm/508mmPower/Voltage2000W/240VWavelength range0.75-1.4umResponse Time1sElectric heat transformation rate>98%Filament Temp2200Max Heating Length6400/ 2400 mmWarranty Time1800 ° - 2400 °CHigh Power Densityup to 200w/cmHeating FilamentTungstenGold Coating Infrared HeaterWhite Plating Infrared HeaterTransparent Infrared HeaterTechnical Specifications ListModel no.Voltage WattDiameterTotal lengthArc
