I have both the I25 Infinitum and the 'T10 3w. Both work as described. The I15 has a slight greenish tint. But the t10 has a nice beam. All in all, I think they're decent lights,
My Olight T10/15 was my first higher end flashlight and I love the thing. Now, I've only had it for a year but it's my EDC and does an admirable job and I love the utility of being able to swap the body to use AA batteries in a pinch. .......
I love Olight and have a T25T. I'd like to get the single AA T15 but noticed that you can get the T10 tube to convert to CR123. But you can also do it the other way around. I'd like to have both capabilities. Do you know which way works best or are the heads identical. I actually started another thread asking this very question before looking here. Anyhow just curious in case you don't see the other thread.
The Olight T10 / T15 head is the same. It functions best with 3V CR123 or 3.7V lion batteries in either CR123 or 14500 format. Better mode spacing and a higher High output.When using 1.5V or less AA batteries, there is little to no brightness change when switching between Med and High modes. I run mine with the AA size tube and a 14500 lion battery. I like the 4" length more than 3.5" when using CR123
