Infrared Differences?... Heat Lamp, L.E.D., and TDP mineral lamp??

I see a lot of different heating methods out there, and would like some help to clarify each. The main three that im thinking of are:
1. Infrared Heat Lamp= they are h.d. style, give off light and heat.
2. L.E.D. Infrared light= they used various led’s to give off a spectrum of infrared light, without much heat at all.
3. TDP Mineral infrared lamps= these are used to give off infrared heat, without any visible light.

Wondering if anyone has used any of these? or if perhaps someone has heard something beneficial over the other types of lamps around.
Thanks.
