The HT-200 is significantly less hot than electric lamps. The HT-200 has the advantage of cooking the paint from the inside-out. In comparison, electric lamps are use too much heat and have a short wavelength of 0-2 microns plus 4000oF, similar to the sun’s rays.
With that in mind, the waves of electric lamps enter the reflection, wrap along the surface and trap either water or solvent. In addition, they create a crust on the surface, giving a false impression that everything is dry. The next day, water or solvents surface and create problems such as scratches, products sticking together or packaging issues.
