I just replaced my low beams with 90W XENON bulbs that I got on eBay for about 12.00$

They are brilliantly blue-white and certainly cast a better light than my old stock lights. I run with my fogs all the time, so I have bought a set of XENON fog bulbs and will install them as soon as they arrive.

Given that the wattage is about double the stock bulbs and that they are a high intensity XENON bulb and the reflectors are identical, how can these fail to provide significantly better light?

This is like the synthetic oil question: totally anecdotal info at best: any optical engineers with the real scoop out there????
