I just received the LumaPower LumaHunter MRV SK Q5 from Battery Junction.
Shipping is the usual fast 3 days to Socal.
The MRV SK uses a Cree XRE-7090 Q5 WD LED driven at ~1.2A/4.25W.
Uses a longer reflector 35.94mm to the 1st Generation MRV's reflector 31.25mm. The longer reflector increases the brightness and throw compared to the 1st Generation MRV's. Also included is a OP reflector.
Can use 2 CR123's, RCR123's or with the M-65 extender 2 18650's.
The MRV SK uses a side switch which controls the 3 brightness levels, high, medium and low. The rear clickie is a forward clickie.
The finish is excellent except for a scratch by my side switch. The Type III Hard Hard Anodize looks uneven in color. The lens bezel is a black color the lens housing is dark brown color. The battery tube is a black color. The Cree module is also a different color which looks to me like a dark bronze color. I gave the grade A- due to the scratch.
The fits is excellent. All threads are smooth. The rear tailcap threads are smooth compared to my 1st Generation MRV which is very rough. I give the grade A. The rear tailcap screws on very easy. I have read that some have some tailcaps hard to screw on.
-------------------------------------------
Pros
Forward clickie
Very easy UI.
Side clickie controls 3 brightness levels.
Fit all batteries, CR123's, Protected RCR123's and Protected 18650 with ample room.
OP produces a very smooth beam.
Price is excellent. I thought the MRV SK was going to be sold at a higher price.
Very easy to swap out the reflectors.
Came with the OP reflector, extra o-rings and GITD rear switch cover.
Cons
Beam is slightly off-center.
Scratch by the side switch.
Mismatch of the Type III Hard Anodize color.

As you can see the Dereelight DBS V2 has a longer a wider reflector. It's going to be hard to beat the throw and brightness of the DBS reflector.

I also took lux readings of the lights shown above. These are the lux readings I got. I am using a Meterman LM631 Light Meter measured at 1 meter. I waited 2 minutes before taking the readings. I am using AW's Protected Black 18650 for the Dereelight DBS V2 Q5 and AW's Protected (Black) RCR123's for both the MRV SK Q5 and the MRV Q5 which were fully charged.
