Had my Xtar WK41 for a while now and I figured I would try my hand at a review! Got this from Gearbest for review and wanted to pass it along.

WK41 Flashlight
So before we get to the stats and info that I copied below I just wanted to do a quick write up on the light. I ended up getting the WK41 from gearbest for review and quickly fell in love with this little guy. Lets talk about the positives first. I like that it uses AA and 14500 batteries, and that it automatically detects between them. The 14500 gives you the higher 300 lumen brightness mode. The modes are very sufficient for my use, and I appreciate that the strobe is easily accessible with a double click. I do carry this with me in daytime alot, and I like that I can use it as a defensive tool as well as a pocket EDC light. The pocket clip is very strong, and has yet to pop off from regular use. It’s reversible and yo can put it onto a cap or hat. The interface is simple, and easy to remember. This light is 100% waterproof and pretty strong as well. I’ve dropped it many times with no bad effects. It also has protection against reverse polarity and over-discharge of the 14500 batteries. This is pretty handy because unprotected 14500s will fit into this. Of course, you should use protected for safety sake, but in a pinch you can use an unprotected 14500. And most important, I have not had one accidental power on in my pocket. Alright… now the negative. The low battery indicator is not accurate at all. In fact the way this light operates is a bit weird. I had it running for about 3 hours at full blast, and instead of draining the battery it reduced brightness slowly over time. I’m not sure if this is intentional, but after 3 hours I gave up as the life of the battery could easily stretch into 10’s of hours when it is dim. I went through a couple AA batteries, and it seemed to be the case. I haven’t drained a 14500 yet to see if it does the same. Although the pocket clip has not popped off yet, I do strongly prefer a clip that is permanently attached to the light. Overall I’m very happy this little light and it is going to see a ton of use!

■In the hidden modes, mode memory and the low-power indicator function are disabled.
■When the remaining battery capacity is very low, the WK41 may flash.
■When the WK41 is not to be used for a prolonged period, it is recommended to remove the batteries.
