for conversation purposes we will use a 6000k or 8000k low beam xenon/halogen or halogen
(a 55w is 4.5 amps, a 65w is 5.4 amps, a 100w is 8.3 amps)

to what purpose does watts (ie amps) play in the brightness of a bulb? most bulbs are 55w low and 65w hi beam (except HID)



so is a 100w low beam brighter then a 55w or 65w
or
is a 100w 6000k low beam brighter than a 55w or 65w 8000k low beam


and
is a higher watt bulb more likely to have a shorter life

First, 100 watt is illegal in street autos. Just like household bulbs, higher wattage is brighter.

Higher-wattage bulbs than the fixture is designed for will run hotter. High-powered (higher than stock) halogen bulbs can run hot enough to melt the plastic parts of the connector that supplies them with power ...

Just saw a Ford F-150 today with Nice, large melted area on the headlight cover. Owner had installed high wattage bulb and paid the price.
