Different types of bulbs give off different amounts of light.
A standard 55w H4 bulb produces 1000 lumens of light. A 55w H7 bulb like that used in the C class produces 1335 lumens, so there is variation in Halogen bulbs depending on the type of bulb.
Also, a standard 35w xenon bulb produces 3200 lumens of light.
The xenon light produces 320% more light than a H4 bulb!
