also with my lenses available...
just got some Ray-II in, and tested with my lenses.
the lenses fit perfect with this one, since the construction has a different reflector.
as such the beam pattern, like on the wide, is crisp horizontal,
the euro spot, now does not show the led die, and is indeed very nice.
with my added high quality mirror surface reflector in the back , there seam no perceived light loss with these lenses.
in case you want it, kit and kaboodle, or just the light head

right now its still cold, and windy, will do beam-shots soon.

since battery tests are time consuming, did one, with 2x the usual current,
what would translate, running 2x lights of one battery.

what would translate, charge at room temperature, do not use for 10min+ after,
discharge, do not use charger for next 20min+.
would mean , you get ~4.00 hrs runtime, +/-7%
under ideal conditions, new battery, room temp charge, good charger, discharge, not in freezing temps, or hot summer, could possible get ~4.25 hrs runtime.

what shows similar performance, in practical terms, same performance battery.

did not get a new battery from openlight yet!, my guess, my thumb X pi, on the new 5800mah battery, with a decent charger, to get ~4.75 hrs = 4 hrs 45 min plus , runtime out of it.
For marketing purposes, you could say,the 5.8ah it's a ~5hr battery, but don't think, you will get that consistent with a MS charger.
Of course, quality and capacity comes with a price tag. And to get maximum capacity, safety and runtime, recommend any Lupine chargers.
----
for the lumen, I don't have a calibrated Ulbricht-kugel ,
so I got to use my Lux meter, and hold my thumb in the wind, multiply with pi and add some grain of salt.
for the original MS start 580 average 550 end (hot ) 530
for the Ray-II start 630 ( did not have time for the lengthy , hot run) +/- 15%
---- ok in practical terms, it has a better LED BIN, and you get 10-15% more light,
yes, it is brighter than the old stuff. No, it is not brighter than a lupine or a Strykr.
..... the 900 lumen manufacturer rating, as usual, under Lab conditions, an hand picked LED bin,
bolted on freezer, feed by an $4500 lab power-supply, under ideal conditions, to maximum power,
----> which non of the bike light run at !!! , so no you can't have 900 lumen, even if you run it in your beer cooler. oh, well, cheers
