I have a Sabrelite 2020 Recoil LED and can honestly say it is nice bright light. It has a very tight beam. It projects a beam pattern in the shape of a square. (A little odd).
In fact, I just got 2 more of them for my nephew and a friend. They both wanted one after seeing mine. /ubbthreads/images/graemlins/cool.gif
A nice light indeed. /ubbthreads/images/graemlins/grin.gif
I totally understand why it's square, it just looks odd when using it.
We are (me) just so accustomed to seeing a "round" beam pattern that the "square" looks a bit odd!
That's all.
It is still one heck of a tight beamed light!
Square or round.
I have an M8. Square hotspot as everyone has already mentioned. Practically zero sidespill. Very good throw. Tight beam. Very white colour. I wouldn't use it for close-up work. Outside up to 100 ft is its intented duty.
BTW, mine has a plastic battery cage in the tube. The cage was cracked when I received it but I just did away with it and I'm currently using it without the cage. Seems to work just fine without it.
You should note that the actual brightness of the Sabrelight was measured at about 650 cd by ledmuseum , not the 1500+ implied by Roy's lux measurement.
The Lighwave Infiniton is the other recoil technology, 3xC light made, and it puts out over 7 hours of 900+ cd brightness, both as measured by ledmuseum.
