Great work, SelfBuilt !

Thank you for this very thorough Update !

Interesting, it is actually really less bright. Smaller difference between max mode on 18650 and CR123/RCR123 cells is probably due to the emitter with lower Vf.

Could be, at least in part. While the 2xRCR/CR123A differences could just be due to sample variation, it seems clear to me that drive levels have increased on 1x18650.

This is evidenced by the high-output on 1x18650 (now directly matching 2xRCR/CR123A), the semi-regulated runtime (hard to see in the graph, but it now matches 2x sources for the first 10-15mins), and lower total runtime. Note that all my runtimes were done on the same batteries used in the original pre-release sample. These 18650 differences seem greater than I would expect for simple emitter variation among samples.

I recall that ti-force's original pre-release sample seemed to also have lower output on 1x18650 sources than 2xRCR/CR123A. Will be interesting to see what his shipping sample outputs look like.
 
Thanks for all the hard work you put into your reviews, selfbuilt. And especially for the updated run-time graphs in this one :twothumbs

All things said, if I could change my light's UI I'd have Max in both sets, replacing High with Max 😗

After using the light every day for the past month or so, I would like to take back the comment above. I am now happy with the modes arrangement as it is. I realised that 3 hours of run-time in the very-bright High comes in quite handy, and the special set with Max/Turbo is there if I REALLY need it. Anyway, that's me, YMMV 😀

Don't worry about it, no offense taken. I know there are more than a few people who may have gotten the wrong idea from my post. It just allows me to clarify so there are no misunderstandings. And hey, That replacing high with max idea isn't bad. Or maybe having max in both sets of the UI is a great idea. I know it was mentioned in another post about someone being the type of person to use their lights on max, i am totally in that group and always carry spare CR's with me too. Hey, welcome to CPF by the way!

It's always enlightening to hear viewpoints other than one's own or the manufacturer's, thanks for sharing yours 😉 And thanks for the welcome, I believe you might be the first to welcome me :laughing:

UPDATE: ...Although many here may prefer this new fully-regulated pattern on Hi, I would note that semi-regulated is typically more efficient, and the gradual drop-off was not perceptible to the naked eye anyway...

Is there a reason why MAX isnt fully regulated? I believe that Fenix fully, or almost fully regulates MAX in many of their lights. For example, in your review of the TK12:

As that graph (and the one in this review) show, the Fenix is actually the exception. Most multi-power, multi-level lights are direct-drive or only partially regulated on 18650 on Max.

I presume this has to do with the trade-offs in the design of the circuits. I've noticed that lights with a wide range of outputs - especially those with really low Los (like the G5) - are the least likely to be regulated on max on 18650.
 
FYI, 4Sevens has confirmed that the latest batch of G5s includes the Max/Turbo mode on the regular sequence, and dispenses with the Lo mode.

The revised sequences are thus:
Max, Strobe, SOS, Beacon
Max, High, Medium, Moonlight

Personally, I consider this an improvement (as recommended in my review). 🙂

I'm glad that I bought the first production run. I find that low level pretty useful. But now I need to buy a second G5 just to try it out the new level selection. Thanks again for your reviews! :twothumbs

I'm hoping to make a killing in the marketplace a few years from now with my Rare First-Generation 4Sevens Maelstrom G5 with 8 modes 😗

But if there's anyone interested, I'd be willing to part with it now for the right price... :naughty:

Thanks selfbuilt, your 100m beam shots are the basis for all of my flashlight purchases so far.lovecpf
This update to the ui has put me over the edge & will order a G5. Have any G5 owners came up with a presure swicth to fit?
Also any opinions on scope mount vs barrel mount for the G5 for rec hunting?
 
Just updated the main thread - I've added some additional lights to my 100-Yard Outdoor Beamshot Round-up, including the shipping version of the G5. Check out that round-up thread for more details. Here are a couple of a relevant animated GIF comparisons:

Man that light looks sweet. I just watched NutNFancy review of 4Seven on youtube. Was super impressed with the founder that NutN interviewed during shot show 2010. I'll have to seriously consider one of these lights for my collection. Thanks for posting.
 
i just received mine today and can tell that its gonna get a lot of use....definitely added to my 'go-to' collection. the only thing that bugs me is that the hotspot has a dark center. my Quark and Quark Turbo both have this but i never thought it was significant enough to matter...ie/can't see it in the field. the Maelstrom i received has a far more prevalent dark center in the hotspot. i won't know its affects in the field until tonight but have a feeling it will show. has anyone found measures that can alleviate this? i'm wondering if it'll help to bore open the reflector opening a little to give the emitted light more clearance. i have a lot of XP-G lights and lamps and the 47's are the only ones that have a dark spot. any suggestions at all?
