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.
