Hi, this is a video about the P25. The reviewer had done some tests about the flashlight. I think there is something you might like. 
If you have any comments or suggestions on this product, welcome to leave a comment.
What is the color temp on the LED and are there any choices?
I couldn’t see it listed anywhere but by eye mine is about 6000K. Maybe 5700K.
Review here: Cyansky P25 review | Tactical flashlight with 3000 lumens
Another great review! Thanks Dave. The runtime graphs do look very impressive with a well driven light, most flashlight companies are very conservative and rather disappointing when it comes to sustained output.
Not taken with the lack of knurling or grip on the body, but I’ll certainly be on the lookout for future models.
The run time charts look great. This is nice heat management without sacrificing output by too much.
Yes. The color temp is about 5700k. Dave is right. :+1:
This is an intermediate value, if the brightness is different, the color temperature will be different.
Thank you, guy. The P25 has good performance, It is a cost-effective flashlight. 
Can a “normal” non-USB charge 21700 battery be used with this light?
Hi, guy. P25 is compatible with 21700 convex-head batteries on the market. 18650 convex-head batteries can also be used, but 18650 batteries are a little shorter, and there may be a little wobble inside when shaking the flashlight.
Thank you for that information !
Good to hear, as I don’t have a charger that will fit the included cell. Having to use a USB charger is not usually convenient for me.
