You've got me stumped. Are you sure you have the right model number? I familiar with the L1 and the L4 both of them are far superior to the X5.
If I can make a suggestion, stick around here for a couple days and read the posts and use the search function. There is a virtual ton of info that is posted on comparisons of flashlight beams, size, shapes, batteries, etc.
