I described the 55w Xenon conversion kit that I chose to install as having more lumens than a 24w kit. The 'standard' conversion kit is 35w, not 24w. My mistake. Here is a link comparing the spec's of various kits offered from VVME:

I hope this is helpful to those who have not made the xenon upgrade.
