Yes, LED flashlights do get hot but nothing too hot to the point where it is hard to hold onto it. As with any electronic device, prolonged usage at a high intensity will cause the inner mechanics to heat up. The amount of heat given off by an ED flashlight is directly proportionate to the amount of energy it is using to power the light. However, LED flashlights are considered 'cool' lights which means that they give off lesser heat as compared to the traditional halogen/incandescent lights.
