Can I run a 10440 cell in the olight I3T?

Title says it all. I have seen videos where it has been done, but don’t know if it will fry it in a short period of time.

I have seen this done, and its pretty bright ! I would just be careful, when it gets pretty warm…shut her down. Olight says ABSOLUTELY NOT, but its a 20 dollar light . If you burn it up dont try to return it just buy another. I have a few of these and like the tail clicker on these.

A lot of people do, myself included. It gets pretty warm but so far I haven’t seen any adverse effects. I don’t run it on high for long though, 30 seconds to a minute at a time.

yes u can, i run one in my copper i3t now over a year but i dont run on highest for very long but i believe its safe.
