Review : Thorfire S70S (2x26650 xhp70 flashlight)

Welcome to my Thorfire S70S review !

A few words for the flashlight :

Overview :

First Look :

Flashlight in it’s box . Box is pretty big , i was surprised … :

Package Contains :

  • Flashlight
  • User manual
  • Shoulder strap
  • 3x O-rings
  • 2x extra rubber boots
  • Extra glass lens
  • 2x keyrings

A closer look :

Flashlight is big enough as you probably guessed , due to it’s 2*26650 configuration and the nice big reflector :

Head has an interesting design with lot’s of cooling fins :

Notice the side switch too …

Notice the hole over the switch to mount the shoulder strap :

Logo :

Look how deep the cooling fins near the led are :

The bezel :

Flashlight has an OP reflector and AR coated glass :

Led close-up of the led , the XHP70 :

And a bonus cool shot of the led :

Tube is a little different , no knurling at all :

It is grippy with this design as well …

The tactical ring , anti-roll design :

Tail switch (on/off function) :

It’s spring is a gold plated one , stiff but it gets compressed nicely .

In the opposite side , in the head , driver is probably a 30mm one , held with a retaining ring . Driver’s spring is strong :

Nice , “square” & anodized threads on the tube (tailcap side) :

E-switch’s nice locator / battery indicator :

Shoulder strap :

In order to use the sholder strap , you need to add 2 split rings :

And the adjustable shoulder strap :

.

How it works (&modes) :

Flashlight uses the switch at the taicap for main power on/off function .

E-switch navigates easilly through modes , but is also used to temporary turn off the light , get in standby mode .
For example , if you turn on the switch at the tailcap , flashlight will be still in standby mode until you press the e-switch .

From standby mode :

  • Single (short) click goes into last used mode , and with another click switch to the next mode (Low-Mid-High-Turbo). If you wish , with a long click you enter standby mode and with double click strobe .
  • Long click (press and hold) enters moonlight mode . One more short click to switch to the normal modes .

When power (tailcap switch) is on , switch’s led is on and functions as locator / battery indicator .

Moonlight mode is very low , awesome.

.

Measurements :

Basen IMR26650 4500mAh were used in all measurements

Lumens :

  • Moonlight : ~0,7 lumens
  • Low : 192 lumens
  • Mid : 640 lumens
  • High : 1532 lumens
  • Turbo : 3220 lumens , after 5 minutes steps down to high mode

Tailcap measurements (amperage draw) :

  • Standby mode : 4,39mA
  • Firefly : 5.65 mA
  • Low : 0.2 A
  • Mid : 0.7 A
  • High : 1.96 A
  • Turbo : 5.09 A

Intensity : 58,8 kcd

.

Beamshots :

Control shot :

Low :

Medium :

High :

Turbo :

Conclusion :

Well designed light , with pretty well spaced modes , from less than 1 lumen to 3k+ lumens . It’s size and weight might bot be ideal for anyone , but having a light that can be so bright without draining the batteries quickly or getting hot in seconds . The shoulder strap is a big plus for me , i find it very useful !
Overall a high quality light , and really bright .

.

Comment if you want me to check something on the flashlight , or tell your opinion . Thanks !

Let me know if it is regulated after the step-down—and if I can click it back up to turbo immediately following. I know the Convoy L6 diminishes gradually in output. That’s a no-go for me.

If you can compare it to the Convoy L6 would be nice Grad

Also, can you use Keeppower 26650s Protected?

I use Keeppower ICR26650 5200mAh 3.7v Protected with S70S, works great for me.

Yes , i believe it’s 5000K , a xhp70 n4 3a .

Will answer every question , but i will have to check them on the light first .

Thanks !

I have not tested if it goes immediately back into Turbo, from the user manual, Intelligent circuit memory – To save battery power and protect the flashlight from overheating, the flashlight will drop down into High mode after working about 5 minutes in Turbo mode. Therefor, the runtime of Turbo output is an accumulated time.

With a code you will still get it under $39 on Banggood No doubt its a very good deal.

Steps down to high after 5 min, you can click back into turbo right after, light still wasn’t even hot for me.

Slow is smooth, smooth is fast.

Just did the test .

Steps down every 5 mins (4m 55s) from turbo to high , and as BeardedRaleigh mentioned you can enter Turbo right after that , again and again .

This is a mystery: you measure it to only 3220 lumens, while Thorfire says 3960 and that “it is brighter” than the old one. The old S70 got these reviews: “the Thorfire has under-rated this one at 3000 lumens.” JohnnyMac measured it: “4,545 OTF lumens and 9.22A being pulled at the tail (2*4.61A). No mods performed and running KK 26650 cells.” – I have s70 and it is brighter than a headlight…. http://budgetlightforum.com/node/44802?page=2

Let’s start with this : On your example , amps at the tail are still 4.61 (same current goes though both batteries), but voltage is double (so it doesn’t draw 9.22 amps as you stated).

For N4 bin , Cree claims 3390 lumens at 4.8 amps , so i think 3220 otf lumens at 5.1amps isn’t wrong . I will have to take a deeper look…

Nice review...

 

 

I've tested mine with 30q's only so far, my lumen count was a bit higher. 

I've got a couple of purple Efest 26650 high drain that should arrive today. (Actually should have got them yesterday  it USPS didn't bring them)

 

I'm very curious of I get a higher tail cap reading or a higher lumen count.

 

We are trying to work a precise way to measure the distance.

 

I know half a mile worked out pretty well.

Measured again lumens , now i get 3402 lunens* at the same amps , seems my initial measurement was a little lower (i think i measured lumens after i took the beamshots) .

*All of my measurements are taken 30 seconds after turn on . Manufacturer can claim lumens at the start-up , which i think it is close to 3600

You can always add a resistor to bump up the power on turbo. You don’t even need to unsolder the driver to do it. I’m awful with soldering small things and mine is working alright.

I don’t know how much it is putting out now but its definitely heating up quicker and is brighter. I don’t have a clamp meter to get an accurate reading on current.

It is a little harder to find the same size but I found a listing on ebay for it. Look for a 2512 r100

I have already installed a R100 on my L6 , works great so far ! Draws around 7.5 amps .

I would change it on S70S too , but i think stock mcpcb isn’t DTP so lumens will probably drop fast…

I can test mine later. I can’t measure lumens but I can see how much the output drops over time.

The drops at 5-minute intervals are of course from the turbo timer.

Started with fresh 18650 30q cells.
Ended at 3.8v after 15 minutes.
Head temp hovered around 140f.

thank you for your review.
I was considering the klarus g20 for my bike, which is also a nice choice. It is incredibly affordable price but incredible performance.
big size of this doesn’t matter. because very low price.

how about it’s beam size? i want to know if it is wide enough for bike.

Beam is pretty wide , i think it’ll be OK …

Are you sure it won’t be big for a bike ? I would take a look at a small light , like the BLF A6 , with 1-2 extra batteries for good runtime .

I agree as a fellow biker (bicyclist at least). If this is going to be used on a bicycle it will be extremely heavy and akward. I personally use a Thorfire C8s with OP reflector and extra cells with me for the longer runtimes when im not using my thorfire headlight. Works great (both)
Plenty of light from the C8s OP… C8s OP is modded though just FYI.

Also a question for me about the S70S……. does anyone know if this light has LVP? I use the protected Keeppower 26650s and sometimes some unprotected AWT 26650s.

Thanks,

Mike
