Mainly convection. Air moves across the lamp and is heated, carrying that heat to the rest of the room. If you touch the lamp, your hand will also be heated by conduction. Air is not highly conductive to heat, so conduction is not normally a significant mode of lamp heating.

The heat you feel is infra-red radiation generated by the filament
Convection can play a part but it travels upward.

current flowing through wires comes to the coil in the light bulb, which is usually made of tungsten, in this coil the current bobards the tungsten atoms from constant flow of current, these atoms then vibrate due to the collisions, vibrations of atoms= heat.
the light comes from movement of electrons, which causes releasing of pure energy, photons, light....just in case you were wondering

just found this...look very useful

looks like they talk about everything on lights, so if you are interested read that site
