Arcadia Deep Heat Projector 80WThe Arcadia Reptile Deep Heat Projector uses cutting edge technology to produce the most natural and effective wavelengths of Infra Red being Infra Red A and Infra Red B. These wavelengths have been almost impossible to replicate in balance within a small lamp up until now. The heat from the sun contains IR A and IR B but without IR C. It is IR C that is produced from non light producing heat sources including CHE. IR C is not effective for deep
