A lightmap is the lighting data of each face. The stored light is then added to the face giving it brightness. Especially common in BSP based engines, it is applied additivley to each face to produce the final lit effect.
Determined during the vrad compile proccess lightmaps are only applied to brush faces as models are lit differently. The lightmap's scale refers to the number of texture pixels per light pixel (luxel). Smaller values means more luxels, thus a better quality but larger BSP size and compile times. The lightmap resolution can be viewed within Hammer by altering the viewmode in the top right to lightmap. It can also be viewed and edited from the Face Edit Dialog.
