I second PD here.

Both the S50 and the S70 produce a massive amount of light and shining them through a tunnel of trees like in the pics would certainly give a result similar to what you see there.

I liked Thorfire before I got the S50 and S70 because when looking at the descripton of the VG10 they wrote something like “the tactical ring is renewed, the older one sucked (yes they sed the word suck) so it needed replacing” this is so not marketing speak (I hate those slick marketing talks) and it won me over.
I bought it. The VG10 is very nice and the quality and preformance of the S50 and S70 seem more then they promise us. (longer runtimes, higher lumens) and combining that with 2 year warranty and a compagny that is responding to people (unlike the unanswered emails I send to Sunwayman about a more expensive light or the stories about Olight being not responsive)

I finally received my light in the mail today. Very happy with an as is factory budget light and that rarely happens. Output, 4 mode spacing, size, it’s all as advertised. Current readings and a thorough stripping is not happening anytime soon. The two mod’s I do see are as follows;

1st thing I noticed is that the batteries are tight regardless of length. Springs are thick and well coiled. One modification I like to do on high amps light is stick these in. http://www.mtnelectronics.com/index.php?route=product/product&path=25_81... Both this and the original spring is 1mm dia. however the replacement is a better material. This should now allow the longest batteries listed to be used. My choice is King Kong 26700 with a magnet. Probably only replace the one under the driver to allow the tail spring to give that battery tight push needed for different lengths.

2nd thing is to look at the driver for a modest current bump.

Output is impressive, but all mods are on hold until my shoulder heals I’m in day 13 of rotator cuff surgery.

This will be my first powerful light purchase. The brightest light I currently own is an old maglite 3D I popped a P4 in years and years ago. I’ve gone a little crazy lately since joining the forum and ordered a half dozen lights or so, but this S70 is the one I’m really looking forward to. Can anyone else confirm that the keeppower 5200 unprotected 26650’s are the way to go? I ordered two of them but will order something else if needs be.

Those batteries should work great in your light. Plenty of current plenty of run time.

I run them in my S70 Smile
Also have a look at this thread http://budgetlightforum.com/node/45506
Apparently this simple mod on the S50, 1 blob of solder, can also be done to the S70 giving a BIG increase in performance, although the S70 is already a very bright light as stock Wink

The Keeppower 26650 5200mAh batteries should work fine.

However, if you’re the type of flashoholic that tries to squeeze every last lumen out from his flashlights, then I’d suggest trying one of the top performers recommended by Mooch:

  • AWT Yellow 75A 4500mAh
  • Basen Black 4500mAh
  • Brillipower Green 80A 4500mAh
  • Efest Green 20A 4200mAh
  • MXJO Yellow 35A 3500mAh

Plus this one, recommended by many of our BLF members:

  • Efest Purple 40A 4200mAh (Tested well by Mooch, but not recommended by him due to one dud cell.)

If you compare the Keeppower 26650 5200mAh curve …



… against those of the top performers, you’ll see a considerable difference (0.3V to 0.4V) in voltage sag under 15A loading.

At the 5A loading of the Thorfire S70, the difference between the top performing batteries and the Keeppower 26650 5200mAh batteries would be much less (say 0.1V to 0.2V). And that difference would be more than compensated for by the longer run times of the Keeppower batteries.

Got myself 2 Heter 4500mAh cells from Gearbest for the S70
They measure 10mR and 5000mAh
And the S70 seems a little bit brighter with them compared to use it with protected 18650 cells I used to test with.
Oh they were $11/

And welcome to BLF!

hey guys i used my lg 18650 HG2 fully charged at 4.10 volts gives me about 4.6 amps at the tail-cap so that puts the figures around 4000 lumen.

On my light the illumination on the side switch is very dim and is barely visible, in the photo’s in the OP the rubber looks translucent, on mine it’s light grey. Even in complete darkness I can hardly see anything. Sad

The bezel is extremely tight and won’t budge, I have strong hand’s too. I’ll try another way.

Hmm mine feels good and lights up fine.
Seems like you should pm Thorfire here on BLF so they can send you a new part.

They might say, “What illuminated switch?” as there’s no mention of it and it’s not shown in the photo’s on their website, nothing on Banggood either

Hello! I got my S70 from BG and my side switch is also grey and the indicator is barely visible. I if some one knows a place to buy clear replacement cap that would be nice.

For some reason the stock output wasn’t that good (turbo 1.7A at tailcap) but after one solder blob turbo went up to 7A and high is now 2A. Much better… Big Smile

Received my S70 from BG yesterday. Same problem. The side switch is grey with very poor illumination.

I’m waiting my S70 from BG too.
Do you think it’s defective batch of S70s?
On this video https://youtu.be/usVnB_lPFQA?t=546 indication is pretty bright.

It could be. The one on the video is nothing like mine.
On mine there is a crescent shaped faint illumination to the left of the T on the switch and a barely discernible tint to the rest.
Its the only fault that I’ve found though.

Doesn’t sound right. Got mine on Amazon and side switch is clear and bright…

So do you have good current on high mode? More than 5A?
What we can do with this tiny defect (i think all flashlights from BG with discount will be with weak side indicator)?

I was wanted buy it on Amazon. But they did not sent S70 in Russia.

I got mine via freeme“s BangGood discount link.
Clear cover to the side switch that shows the green, orange & red well.
The cells are on charge & I will post a tail cap reading later.

I find it strange that the illuminated side switch isn’t mentioned in the product information, maybe it wasn’t reliable so they changed the switch rubber to grey and withdrew the information with regard to the side switch in their product information.

Side switch issue. It’s an 11mm switch botton. The retaining ring screwed out with thumb tension on mine. It does have 4 notches for needle nose pliers. Be careful or you’ll stab the electronic switch.

I don’t have the means to run any tests. Sorry.

Just done a tail cap test with a pair of freshly charged Keeppower 5200 mah IMR“s & got 5.24A.

I got my S70 from BG via freeme discount and all is well. Not as bright as my modded J18 but that will change when somebody is kind enough to post a how to mod of S70 video (so I don’t break anything). Actual lumens seem higher then those on spec sheet, but that is just by eye. Old Lumens has tested turbo at over 4500+ via sphere but I don’t recall any mention of other modes. I am using king kong batteries.

A simple single blob of solder is all that is needed to take the amperage up over 9A http://budgetlightforum.com/node/45506

the S70 is a bit more “complicated” to open+mod as it has no pill

unscrew the battery tube
unscrew the driver retaining ring
tilt the driver in the cavity (watch out not to rip the eswitch wires!)
find the resistors ans place a solder blob over one
remount
done

PLEASE NOTE
i do not work in "reviews, deals and codes" for the time being
maybe M4D M4X will return one day, but until then:

THANK YOU FOR YEARS OF YOUR SUPPORT AND FRIENDLY CONTACTS!

Nice! Thank you. Is a spring bypass required? Any guesstimate on lumen output after mod? How does the mods effect lower modes?

Cheers!

Try using the light first. Even in stock form it is very very bright. I would have also liked to de-tune it a bit from where I have it now, but I didn’t have any low value resistors.

What exactly did you mean by “liked to de-tune it a bit from where I have it now”?

- Is 9A too hot? Or is it just too much wasted energy?

- And what would you have liked to have targeted … 6A? 7A?

Overall, was it worth hotwiring or would you have been happier with just the simple spring bypasses?
