The bulb bulb is much too crookedly positioned in relation to the fixing flange, I don't think the defect can be remedied from the headlight adjustment so that it has the correct luminous flux. Poor quality.
Not quite sure if it as bright as 100W should be, but I can confirm, that it is brighter than a standart 55w bulb. In general, happy for the price and the outcome. Hope bulbs gonna last.
