Conduction: Heat travels via Metal parts on Bulb Convection Current: Hot air around bulb rises and cool air replaces it thus heat from bulb will consistantly warm up cool air around it. Radiation: Bulb is bright and shiny, thus emits infra red radiation. These are my opinion and they are not model answers. Mr Lin. from Singapore zillusia100 a.t. yahoo point com point sg
