High Performance, High Efficiency Radiant Heat
S-Wave high intensity low light radiant heat produced by Solaira, like sunshine, gives warmth you can feel the instant the heaters are switched on. Consider a cool cloudy day that becomes instantly warm when the clouds move and you are in full sunshine. The air temperature did not change but what you are feeling is the shortwave infrared produced by the sun…like Solaira Heaters. This shortwave infrared IS NOT DANGEROUS ULTRAVIOLET (UV) as this is another part of the spectral wavelength produced by the sun.


Comfortable Radiant Heat
Solaira S-Wave low glare quartz halogen emitters lamps consist of a tungsten filament heated by the passage of an electric current to a temperature of 2400º Kelvin. At this temperature, most of the output (emission) is in the short wave infra-red band (1.2 microns). However, as with all tungsten filament lamps, the tungsten will evaporate in time and deposit itself on the wall of the lamp. To prevent this undesirable effect a small amount of halogen gas is added to the envelope of the lamp and hence a process of re-composition takes place as the tungsten evaporates it will combine with the halogen gas to form tungsten halide and so prevent the tungsten being deposited on the wall of the lamp. The tungsten halide will recombine with the filament releasing the halogen and re-depositing the tungsten on the filament. This process is a continuous one and is known as the halogen cycle.
