What difference does the filament orientation make in beam output? I see a lot of different types of halogen bulbs, mainly H1, H4 and H7. Some with the wire filament stretched out horizontal across and some with the filament on-axis with the reflector. The H1, H7 and HID bulbs being examples of the latter.
What difference does the orientation of the filament make? Does a filament that extends on-axis with the reflector throw better than one that extends across?
thanks
