Thank you DJOZZ,

First of all thank you for your scientific answer :slight_smile:

I had a look at these two flashlights you mentionned and they also look the same. I thought that the best angle could be achieved by lamps such as the JAXMAN where you can zoom in and out and where the lense is convex, like an eye.

I have those cheap 18650 lights with zoom in and out, and they show a perfect beam with same amount of light, but only indoors.

I forgot to mention in my previous post that after lot of research, i ended up with the H600FW from Zebralight. How does it compare with the BLF Q8 ?
