When the indicating light on the side switch turns from blue to red, it means the batteries should be replaced or charged.
- Battery Replacement:
Take off the tail cap, insert four 18650 batteries into the battery carrier, put the carrier into the flashlight and screw on the tail cap. With either end of the battery carrier towards the light head is OK. But make sure the batteries are correctly inserted into the carrier with polarities matched (springs on the carrier should connect with the cathodes of batteries).

The only thing is it can't stay on turbo for long. It does last that 1.5 hours on Turbo. To find out, I had to put the light in the refrigerator. It still got hot so I had to transfer it into the freezer. The other thing is the paint comes off easily, and the strap has metal ends that chips where it makes contact with the light.
Laser beam with spill
Posted by Robert on 29th Jan 2018
I had wanted this light for a long time before I bought it. I already had a TN31 and a Nitecore TM26. I did not think I needed this light...until I bought one. A laser beam with spill. I have not taken it out to the country yet because I had to get the right batteries for it. This light is just the right size and is a lot smaller than the TN42 from what I can see in comparison videos. It comes with a shoulder strap, but it almost doesn't need one. Very light in the hand. I keep it in a Pelican 1300 case for search and rescue. You can just pull out the foam from the box this light came in and put it in the Pelican case. Fits well. In the room left over you have plenty of room for a 4-cell charger and extra batteries. Now you have a searchlight kit ready for any search and rescue situation. I still need a battery pouch with 2 sections to separate the spent batteries from the good ones in case of an extended rescue operation.
You'll like the UI on this light. It is identical to many of Thrunite's other lights. This is refreshing because it is extremely difficult to remember all the ways to operate all these other lights you purchase over the years, so they mostly get put away and not used or you end up giving them away, which is what I have been doing lately. I will not be giving the TN40 away! I'm keeping this one.
