I think he meant that the T2 is a little brighter than the T1 (125 vs. 100 lumens). I agree that the T1 or T2 will be a great replacement for your X5. I have the T1 and have had a couple of X5s (both got stolen). The T1 is 100 lumens and the newest X5 (with Nichia CS l.e.d.s) is less than 30. Regulated runtime for the X5 is about 6 hours. Regulated runtime for the T1 is over 4 hours. Tint will be warmer for the T series lights than your blueish light X5.The T2,T3, T4, and T5 will give less runtime but more brightness. I think 100 lumens is enough. Any brighter and you can't use it for close range tasks (hotspot gets to be too bright). Make sure you get the 2008 version T series light. The 2007 T1 is rated for 85 lumens (mine seems a little brighter than the 2008 version) and only lasts 1.5 hours regulated. The 2007 version also uses a K2 l.e.d. so buy from a company verifying which model it is. If you go to a store, look at the runtime and brightness on the box and make sure they're not too low.
I was comparing the INOVA T1 vs the INOVA T2.Both the T1 and T2 are much
brighter than the X5.Thanks for pointing that out as I was already offline.:thumbsup:The X5 isn't regulated AFAIK, the 6 hr run time is when the light hits 50%.Even though the X5s output is greatly diminished after 6 hours it should provide at least several more hours of usable light in an emergency.Many regulated high output LED lights will not work once the batteries are depleted to the point where they can not provide enough power to run the light in regulation.
