Have you never heard of Speras? You are not alone. Speras Lighting is a new player in the world of flashlights. Their lineup is currently very small, with only 5 flashlights. With the T1 being the farthest throwing flashlight. The other 4; Speras M1, E1, E1PRO, and E1T are all tactical flashlights. And to be honest, the T1 is a great throw at fame! Speras lighting did their homework!

Instead of using the popular CREE LEDs they researched a bit and used the Osram CSLPM1.TG LED instead. That is currently one of the best “throw LEDs” in the world. It’s a bit bigger than the CSLNM1.TG, which is 1mm2 (1 square mm), while the CSLPM1.TG is 2 square mm. The latter has a higher output.

It’s going to be a pencil beam for sure, and we are excited to test it!

What you’ll get:

The packaging is pretty good. Much better than some other well-established brands.

  • The Speras T1 flashlight
  • Holster
  • Spare O-rings
  • Lanyard
  • Manual

Handling of the light

I need to double-check its spelling each time, Speras, and not Spears. The Speras T1 is a 2*18650 battery flashlight with a cigar grip. To be honest, there aren’t very many throwers with 2*18650 in series! This makes it a pretty long flashlight.

It has 2 switches. 1 at the rear and 1 on the side. The rear switch is used for power, the side switch is used for modes. The rear switch is a Forward Clicky. This means that you can half-press the switch to power it on.

I like the idea that it has a power switch, so you don’t lose any battery juice through a parasitic drain. Flashlights with electronic side switches have a tendency to self-discharge at any rate. Just something worth mentioning if you are going to store this thrower in your truck, for example.

The side switch is large and has a small indicator LED in it!

This is definitely a huge PRO. There are just too many flashlights with side switches that are hard to find or even hard to push. This is another benefit!

The shape of the light is something that you either like or hate. Well, I don’t have much of a preference since I can see the use of most types of lights. Since I started reviewing, I became a little less narrow-minded when it comes to different flashlight applications, etc. When I go out, I just look at all the flashlights I own and quickly assess what would be the best for the upcoming situation.

Since it’s so thin and long, it’s not very hard to hold.

If you don’t like to carry it in your hand, you can always use the dedicated holster for on your belt, or use the lanyard!

One more thing I’d like to mention is that it doesn’t really tail-stand.. lol.

Build Quality, knurling, threads and anodization

New flashlight manufacturers usually start off on the wrong foot. Speras Lighting doesn’t do this in that regard. Their build quality is very good. The threads on both sides of the battery tube were machined very well. There is anodization on one end (towards the tailcap) and bare aluminum on the other end (towards the head).

Anodization is done pretty well, but I saw some missing pieces on the tailcap threads. This is something other major brands also have trouble with. I’m thinking about Klarus. I noticed the spots after taking the pictures so I don’t have any close-up pictures.

LEDs, Lens, Bezel and Reflector

We already briefly touched upon it. The LED is a Osram KW CSLPM1.TG LED. This LED has an extremely small die, without a dome. This means that it is great for throw. And that is what it is really good at.

Its brother, the Osram KW CSLNM1.TG has an even smaller die surface, so it outperforms even this LED at close range, but produces less Lumens.

The reflector is smooth and deep. The bezel is glued so I can’t take it apart easily. The tint is cold, as can be expected from this LED. When pointing on a white wall, it has a sharp hotspot, but when you get farther away from the wall, the hotspot isn’t clean anymore. It’s a little hard to see in the pictures below though. But again, flashlights aren’t made for white wall hunters Lol.


  • Length:  241mm ( 9.48 ”)
  • Head diameter:   63.5mm ( 2.5 ”)
  • Body diameter:  25.7mm ( 1 ”)


  • Empty:  284 g (  10.01oz)
  • With batteries:  375.5 g ( 13.21 oz)

Long-range flashlights

Size comparison with some of the best flashlight throwers I personally own.

From left to right: Lumintop GT Mini, Astrolux FT02, Weltool T11, Astrolux FT03 and Speras T1

Driver & User Interface:

The driver is straightforward without any special modes, except Strobe. It uses 2 switches. 1 power switch on the back, and a side switch to change modes.


  • Low, Medium, High, Turbo

Rear Switch: From OFF:

  • Half-press: last used mode
  • Single-click:  to last used mode, mode memory
  • Double click: Strobe

Side Switch: From ON:

  • Click: Cycle through the menu from Low to Turbo
  • Double click: Turbo
  • Press and hold: Standby

Blinky modes menu:

  • Only 1 blinky mode: Strobe. Double click with either side switch or rear switch.

Low battery warning:

  • Yes, using the LED indicator in the side switch

Lock-out mode:

  • No, but you can use the rear switch to turn it off


  • Not visible by eye

Firmware / UI Conclusion:

The UI is straightforward, without any crazy hidden modes.

Batteries and charging:

The Speras T1 was provided with 2 18650 2600mAh USB batteries. The batteries have a built-in charge system so you don’t need separate batteries for this light. Especially great if you don’t want to carry a separate charger with you. It uses a Micro USB port to charge.

The batteries are quite a bit longer than regular non-protected, flat top batteries. Below, you can see a comparison with an old Sanyo 2600 mAh unprotected battery.

The T1 uses springs on both, the driver and tailcap side.


All of my readings were taken from fully-charged Speras R26 2600mAh.

Amp measurement:

  • Low:  0.01 A 
  • Med:  0.16 A 
  • High:   0.65 A
  • Turbo:  3.27 A

Lumen measurements:

All output numbers are relative for my home-made Integrating Sphere and is now set up with an Extech HD450 Lux Meter for measurements. For extremely bright flashlights (above 5000 lumens) I am adding a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 137 lumens.

Tested with 2 Speras 2600mAh batteries

ModeSpecsI measured:
Low2 Lm1.58 Lm
Med100 Lm120 Lm
High400 Lm445 Lm
Turbo1200 Lm1196 Lm


Turbo mode:

From the runtime graph we can see that Turbo lasts about 2.5 minutes, before it drops to 500 Lumens. That’s a little bit of a shame. It’s still roughly doing 150,000 cd at that point. So still not bad. But a pity it doesn’t keep turbo longer.
Runtime is just short of 3 hours. The T1 maintains an output of about 1 Lm for a few more hours. But I stopped the runtime at 4 hours and 40 minutes. So I’m pretty sure it will last at least 2 hours on a very low output.

High Mode

In High mode, the Speras T1 has an extremely steady output till about just short of 3 hours. If you compare this with the runtime graph of Turbo mode, it’s almost identical, except for the first 2.5 minutes.

Throw measurement:

Measurements were taken outdoors with a professional Hagner E4-X Lux Meter. 
I got the following readings:

ModeSpecifiedI measured
Low704600 cd (49m)
Med35,20842,400 cd (412m)
High140,833157,600 cd (794m)
Turbo422,500 cd408,000 cd (1277m)

Maximum beam intensity is over 400Kcd (almost 1300 Meters/0.8 Miles)  which is amazing for this kind of a light. The Osram white flat is an amazing thrower LED. The only downside is the runtime in turbo.


For the following beamshots, I went outside and compared the Speras T1 to other popular flashlight throwers. You decide for yourself what type of flashlight you need. The T1 is doing a phenomenal job in throw. But it doesn’t have any spil.

Dislaimer: The flashlight was sent for review by the manufacturer.

Overall conclusion


  1. Great thrower
  2. Includes 2 18650 USB batteries.
  3. Simple, straightforward UI
  4. Nice amount of accessories


  1. Turbo mode only lasts 2.5 minutes

Overall Rating: 4 stars: ★★★★

The Speras T1 is clearly a dedicated thrower. It doesn’t have any useful spill, so if you are looking for an all-rounder, this is not it. The Osram LED is a game-changer. Probably the #1 throw LEDs in the world. The Osram CSLNM1.TG is the 2nd best throw LED in their lineup. But it is able to push out 1200 Lumens for 2.5 minutes. This is also a CON since you won’t be able to use it at max output for longer than that. If you are looking for an affordable, small thrower, this might be it. It throws farther than the Lumintop GT Mini, the Weltool T11, Astrolux FT02, and FT03.
