The beam is a tightly focused spot with a big, relatively bright halo. I took it diving in 30-40 foot visibility and it was doing well against my primary 1200 lumen LED canister. It was not as tightly focused as the primary, which is a true lightsaber, but it would do in a pinch, and the primary cost over $1000. I am now trying to figure out the best way to attach it to a goodman handle so I can try it as a travel primary on a trip.
I just compared the beam to an Intova ICOM I have here and they are almost identical beyond the massive difference in brightness. The SL1 halo is maybe 5% smaller, but has the same hotspot characteristics. The halo on the SL1 is also super smooth, with no dark rings.
It is really amazing how much LEDs are advancing and how fast. To have an 800 lumen light running of 3 C-cells for 7hrs is just nutty IMHO.
