Selfbuiltās review of the Niwalker BK-FA02 was very positive. Really wish they had hidden the strobe. Who uses strobe on a light like this anyways?!? Really.
Kind of torn between BKFA02, 7G10, and S2200, but leaning SF currentlyā¦ I am a fan of both SF and Crelant brands. No experience with Niwalker, but I hear they are awesome.
Like the appearance & proportions of the SF best. Surprisingly, the Crelant claims to only have 6mm fatter body despite being 4-cell vs the 3-cell S2200.
SF seems to have better build. 7G10 cannot be locked out and has rough threads [per turboBBās review on youtube]. That might be the deal breaker for me. This would be my most expensive light. I canāt tolerate flaws like that.
Niwalkers sound great from Selfbuiltās review, but I expect the price to be highest and probably out of my range. Technically, all of these are out of my price range lol. Also think the Niwalkers look kinda funky. The least aesthetically pleasing of the three IMHO. Just my opinion of course.
Strobe on the Niwalker isnāt too bad - just donāt turn the magnetic ring to the left lol. I have the Supbeam K40, where the strobe is past the highest mode on the ring, and that is not so good imho.
turboBBās has made a brief video review of the Crelant and it didnāt seem too impressive to me, with very poor threads.
If that was the video I watched, he kept saying ānot bad for a first versionā. The review was pretty good I thought, because he seemed pretty honest about both the bad and the good.
Yeah strobe past highest mode is even worse. Definitely.
I would prefer some kind of hidden strobe like flick the ring back n forth 3 or 4 times OSLT. Thereās some control ring lights like that but I donāt own them and Iām blanking on what it was now. Iām sure someone else knows.
Woohoo! My S2200 hit my Post Office 6AM this morning! Looks like todayās the day! I was hoping as much, and have 3 cells ready to try it out. Is there any real issue with using 2 AW 2600mAh Protected cells and 1 RediLast 2600mAh Protected cell as long as their Voltage is same or very similar? 4.22 4.21 4.20 with the 4.22 and 4.20 charged on my UltraFire WF-188 and the 4.21 charged on Cottonpickers USB 700ma charger. These are measurements taken on rested cells, just read em at 9:19 and they were charged yesterday afternoon.
Edit: the one at 4.22 quit at 4.14 (the charger got moved and it broke connection, this charger is funny that way with sliders that are very coarse in movement) and I put it back onā¦it stopped well after the original pair started with that 4.22 showing.
I donāt have 3 of any same battery, got pairs as one was always a backup to the other. Iāve got 2 AW 2600, 1 AW 3400, 2 RediLast 2600, 2 Panasonic NCR18650PD with 4 more of the Pannys on the way.
Correction, I DO have 3! I raided my wifes P1D and found a matching AW 2600 Protected.
Edit: Sucks getting old, I would have bet money that the cell in my wifes P1D was an AW 2900mAh Protected cell. My memory is horrible. Scary, isnāt it? I use Li-ions.
Can anyone guess what I have in my hot little hands?
6 days from Hong Kong to Central Texas, must be a new record.
Itās Big!
Itās Black!
Itās Impressive!
So, what is it everyone wants to know? The MT-G2 is freakin huge! The reflector is gorgeous with a light stipple that shows the emitter very well. No artifacts, nice hot spot, good spill. Beautiful tint. Slighter whiter than a Nichia 219 but very reminiscent.
Iāve got 3 AW 2600mAh cells, fresh charged but rested. My DMM is a cheap one. I use a 1.5ā long piece of 12Ga copper from Romex to take tailcap readings. Some will be disappointed with these numbers, but remember Iām not a reviewer and am not experienced with this kind of thing. But, that said, Lo shows .08 Med shows .700 and Hi shows 2.11A. So, is there a multiplier in there with 3 li-ion cells in series? Somebody please tell me what these numbers mean! Seem low to me.
I will try to get some pics this afternoon, and some beamshots tonight. Beamshots against a couple different lights but only one of known output. That would be the EDC+ Triple XPG at 720 lumens OTF.
It is a very impressive looking light, to be certain. Perfectly executed with not a single blemish on it that I have seen so far. Pics to follow.
Edit: Can a Serial # of 9 mean I actually got the 9th one? Radical!
Nice, Iām really looking forward to more of your impressions of this beast.
Assuming voltage of freshly charged cells quickly drops to 4V apiece at 2A, 3(4V)*2.11A equals ~25 Watts input power. Assuming 90% driver efficiency that means ~22.5W to the emitter. Going on that assumption and the assumption that the MT-G2 is dropping 6.3V we can assume the emitter current is 3.6A
12V*2.11A*90%Ć·6.3V=3.6A

If they didnāt change the driver from the S1100 (I would be surprised if they did), the S2200 fully drives its MT-G2 :bigsmile:
Sounds good to me! Itās bright, donā know yet how far it throws but the beam is very nice, think Iām really gonna like it outdoors. When you hold the mode button (lit green with good charge) down for a couple of seconds it goes into a strobe, I kept holding it down and the strobe seemed to get fast, beamshot on the wallā¦.my eyes began to swim! lol I know some are affected by that more than others. Iām usually able to look directly at a strobe with none of that disorientation effect. From 8ā away with the beam on a white wall, things were getting a bit wonky. Very effective strobe on this one!
Not a lot of pics for me to take, as itās the same body as Foyās review. So thereās not much point in my trying to do-over Foys shots. But the reflector and emitter, ahh, beauty in the beast!
Processing a couple of pics, will get em up in a little while.
But if you run the numbers like scaru showed above with fresh cells at 4.20V itās more like 3.40A getting to the emitter at start-up. So between 3.4A and 3.0A from start to moderately run down. Does that sound about right? Seems like they did a pretty good job here and didnāt keep it super conservative like they did their M3 head.
The S2200 shot on the wall (dark paneling and some pictures, daylight) at about 10-12ā just simply blows the doors off my HD2010 thatās pushing around 850-900 lumens. Shine the HD2010 first and totally make the hot spot go away with the S2200. Which is pretty dang good, considering the HD2010 is modded fairly extremely and hits 350-450 yds pretty well. (Pulling 2.88A from a Powerizer IMR26650 [LiNiMnCo] with XM-L2 on copper driven with a stock Q-Lite)
Well, if it was run off of a 4.2 volt power supply then it might do 3.4 amps, but the voltage of the batteries will sag quite a lot. If you want to be optimistic use 4 volts.
Ok, I surrender. I donāt know the numbers or the forumulaās so I wonāt even try to speculate. Iām sure yāall will figure that out soon enough and Iāll sit back and read it. Wonāt understand it, but Iāll read it.
Looking like it could rain, hope I can get beamshots tonight. Wonāt be here at all tomorrow or tomorrow night so it might be a few days before I can get back to it if it rains tonight.
That might be the deal breaker for me. This would be my most expensive light. I canāt tolerate flaws like that.
