Fantastic video. Thanks. That is one monster light.
I’m glad that it has a battery pack -you can charge it way easier than getting out 6 18650 and charging them instead… but a battery holder would be a nice option too 
the sad thing about it for me (except the price of course) is no nw version and not using xml2
are you saying that this rc40 throws the same as the tk70? if so, i have to get a rc40 also! thats assuming the rc40 is floodier than the tk70 right?
Excellent review.
Nice light, but even with the extra accessories, battery pack, etc., I think it’s about $100.00 overpriced. I’ll have to pass unless some retailer has it for a third off retail.
just watched the beamshot video, was expecting to see a tk70 comparison at the end, but nope.
now its hard for me to make my decision, i had a tk70 so seeing the beams together and seeing what the differences are, would have helped.
but now, it didnt really impress me when it went against the tm26 and tk75.
just kinda makes me want a tm26 or tk75 instead since it was pretty close and at a smaller size.
i was impressed when it was the sr90 vs rc40 though!
I heard somewhere in the video Patriot mention both of them throw about the same.
Definitely RC40 throw better than TK75, so should be very close to TK70. And with shorter battery tube, and floodier, looks good to me.
I see huge difference between TK75 and RC40 beamshots in the video. Maybe you have different and higher expectation for RC40.
Below is RC40 top vs TK75 bottom beamshots at 100m I cut from the video. For 100m, I consider it is big differences. It is very subjective to different people different expectation though.
Dengoh, you are right about the brightness being very subjective. To you, the difference appears significant. To me…I hardly see any difference.
I believe the difference is more pronounced in-person, though.
LCD monitor is another factor.
This might help to emphasize the difference more clearly
Mouse out RC40 - Mouse over TK75
The RC40 and TK70 has about the same lux ratings from the manufacturers, but at 3500 and 2200 lumens respectively.
So it means that both lights will theoretically have about .25lux at the same, farthest distance. Will it mean that the difference of 1300 lumens goes to the spill of the RC40, and will illuminate a wider area?
Thanks for the mouse over. It does show the difference clearer.
I would really love to see a longer distance distance comparison of the RC40 vs TK75.
This review was done at only 100 meters, which really isn't enough of a distance to appreciate differences in throw.
At 100 meters, even a pocket EDCable thrower does well... http://laserpointerforums.com/f66/flashlight-beamshots-collection-81167.html
Those were at 75 meters for the far away trees... still way too close to get proper perspective.
yes after seeing the mouse over, it looks a bit more dramatic now. but all that put aside, as long as i know it suppose to throw just as good or better than the tk70, and if also flooder than the tk70, then beamshot comps with the tk75 and the tm26 does not matter to me regardless of how close i thought the competition was, because i owned the tk70, and i know what kinda beast it is.
so the rc40 is a winner in my book, but geez, $350 or whatever it was….is alot of money. gotta find it on sale somewhere for $299 hehe
I am waiting for lower price too while saving money. But just spent some to get Olight M22. From now on, I will not buy any flashlight until I got RC40. 
I personally don’t care fore the battery pack setup. I just had a pretty good scare with my SR90 and with its battery pack. After just a year of ownership, and only perhaps 3 charge cycles, the light failed to charge. It stuck at about 35% charge and would not charge no matter what I did - cleaning it, different wall sockets, etc. Replacement packs are about $85 minimum. I finally took a chance and bought a car charger since it was only $15. Well I lucked out. Sort of anyway, since I was able to finally start charging. So apparently the original charger went bad. It’s good at least the light itself is ok and the battery pack is good. But now I do have to spend about 6-8hrs charging it in my truck.
So this recent issue turned me against battery packs.
It is not battery pack giving you problem then. So far I haven’t heard battery pack failure. They should last as long as single 18650 cell, might be even better because with 6*18650 in one pack, they can supply high current without too much stress.
For me, a failing charger can also easily be remedied by substituting a hobby charger, much less expensive than replacing a non-user serviceable original battery pack.
I understand it wasn’t the battery pack that failed me. But that issue popping up and the chance I might have to spend another $85 for a 1yr old light made me weary of this type of setup. It is convenient having the included battery setup and easy charge ability. But if and when issues do pop up it does make things more difficult.
