Hi, I've noticed from looking online that some lathe owners use regular light bulbs and some use infrared bulbs for warming blank vinyl prior to cutting.
are their any particular benefits to either type? Or are there more efficient techniques for warming vinyl that are worth looking into?
thanks for any input
Infrared Heat and regular bulb Heat

i think there is need to investigate the difference between incadenscent lamp and IR.
I haven't done any tests but at the moment i use incandescent lamp. This is for light that I need and it heats...
i heard that some materials does not take that heat as good as others.
this is what wiki says. I think it is usefull info
For practical applications, the efficiency of the infrared heater depends on matching the emitted wavelength and the absorption spectrum of the material to be heated. For example, the absorption spectrum for water has its peak at around 3000 nm. This means that emission from medium-wave or carbon infrared heaters are much better absorbed by water and water-based coatings than NIR or short-wave infrared radiation. The same is true for many plastics like PVC or polyethylene. Their peak absorption is around 3500 nm. On the other hand, some metals absorb only in the short-wave range and show a strong reflectivity in the medium and far infrared. This makes a careful selection of the right infrared heater type important for energy efficiency in the heating process.
