I guess after they released the AAA Ti3 which could do just the same output with a much smaller size they decided to step down. I ordered a ti3 in stainless. I was and still am impressed and thought this could replace the bigger t10. But T10's great clip and longer runtime and tailcklick and true mode memory are well worth the larger diameter The ti3 now sleeps in a backpack pouch as backup light. the T10 is still used daily.. the ti3 is however the best ever flashlight if you need to check your newborn's sleep. the default moonlight is very low 0.05lm (half or even less of T10) and when it was off for more than a minute or so it always starts on low. perfect in picth black. else the ti3 is just as bright as the t10, albeit with less runtime ofcourse. awesome AAA light next to the bigger brother.
