Geez - that’s what virtually no spill looks like. 
Not sure which is more impressive the picture quality of the phone or the light sabre
While light sabre is not for everyone however in real life use, it has its own merit in instances were there is a lot of floating dust or debris in the air and penetration to your target to a very far distance is needed.
Aspheric light owners can attest to this.
I took those photos while we where near a beach front and pinpoint light concentration to far away buoys and boats was no big deal for the Deft X.
