Astrolux FT03 Mini Review (Thrower, 4200 lumens?, USB-C, Aux LED)

Today I have A recent light from Astrolux the FT03 Mini, it’s the smaller version of the FT03 I tested last summer. The Mini has some different LED options, and runs off an 18650 or 18350 battery and has RGB Auxiliary LED’s. Thanks to Banggood for sending this too me to review.

Pickup the new Astrolux FT03 Mini at Banggood Use code “BGAU1101” to get the light for US $35.99.


Packaging & Accessories

The astrolux packaging is a heavier cardboard box with a line drawing of the light on the front, and a sticker on the side showing the specs you received. Inside you g et the light itself, a 18350 tube, 2 spare orings and a smaller lanyard. You get a manual too that’s fairly long, but the diagram for Andruil is pretty small.


Overall construction of the mini is pretty much identical to the original except scaled down to fit the 18xxx profile batteries instead of the 26650’s. Threads are anodized and ACME cut, the tail still includes stiff heavy duty dual springs. 



The body tube has 4 milled flats instead of 2 but that’s about it. It’s nice they include the 18350 tube here too instead of making it an add on. The button looks and feels the same, and it features the same LED indicators underneath. A slight difference is the charging port cover and how it attaches to the light itself.

To me the diameter of the head looks to be slightly smaller than proportional to the rest of the dimensions, this doesn’t surprise me as it makes the light more carryable. You still have a lightly crenulated bezel, and an anti reflective coated lens with a smooth reflector. 


Size & Weight

Maximum length is 145mm, maximum diameter was 44mm, minimum diameter was 24mm.The weight with a Sony VTC6 is 181.6g, compared to the original with a battery was 397.7g so less than half the weight. The light IPX7 water rated but Astrolux makes sure to note not to submerge it in water. 



Not much to say here on retention, due to the head size it’s not a light i would EDC in a pants pocket but it does work well in a jacket. The light has a lanyard attachment point on the tail cap. No pocket clip is included or designed to fit here.


LED & Beamshots

There are a couple different LED and Tints offered with this light, there is a SST40 option, and Cree XHP 50.2 at 5700k or 6500k, I have the warmer tint XHP 50.2 model here. The driver in use is the Texas Ace Avengers driver, with aux capability, so in practice the light is actually different from the full size FT03. The beam is tight but not like the lights with the flat top LED’s like the Acebeam L17 or Lumintop GT Mini, it’s a more broad beam which I think isn’t bad, I think it’s a more useful beam for most cases.


There are 4 very small RGB LED’s around the main LED inside the light, By default the light comes in Rainbow mode like you see here with low output, I have it in high output here so it shows a bit better. Through the UI you can set it to a constant color, rainbow or volts mode. 



I did my runtime test with a Sony VTC6 battery, and a Vapcell 1100mAh for the 18350 test. I tested directly out of the package without adjusting the thermal configuration since this is a bit of an advanced feature and I don’t think many people will actually do it. That said for best runtime you should.


Runtimes with the 18650 were a bit unstable but pretty repeatable. With both batteries it gets about 3.5 minutes before stepping significantly down to about 5% relative output but then as it cools off output steps up again as you can see from the graph. Most of the output is under 20% though, so on this one only keep it as bright as you need it to maximize runtime and output. The total fon the 18650 was 1:42:30, and the maximum runtime on the 18350 was 0:32:30. Heat wasn’t a major factor with this light while in use with it’s fairly aggressive thermal throttling.



The FT03 Mini features Andruil UI and by default ships in ramping mode which is where I leave it. Stepped mode is available and easy to switch with a trippple press. Double press to go to turbo when on. Andruil is a good UI but complex for a beginner as it has a significant number of modes and options. The manual that’s included does a decent job of explaining things but is very small text. I would encourage you to go take a look at the full Andril diagram and study it if you pick up this light. If you are interested in a more detailed overview of Anduril check out my review on the Lumintop/BLF FW3A. 



The light does have USB-C onboard in the head for recharging. It does require the use of USB-A to C cable for this to work. I did my recharging tests with a Sony VTC6 battery (3000mAh) and saw max charge rate at 1.65A, with overall charging taking 2:02:00 minutes. I ran the same test with a VapCell 1100mAh battery and saw the same charge rate, overall charge time was 0:42:00. I had no issues with using onboard charging for the 18650 batteries but for an 18350 this is faster then I prefer to charge mine so I recommend using an external charger like the VapCell S4 Plus to do this and choosing a slower speed more closely in line with 1C for overall battery life.




  • It’s just fun with the 18350 tube installed, but much less practical in terms of runtime
  • Andruil UI is highly flexible but also not really easy to use.
  • Nice selection of LED, Tints, and Body Colors



  • I think the claims here of 4200 lumens are probably optimistic at least on my copy when I compare it to other lights I have. 
  • Aux here is more of a cool thing rather then super useful as it’s fairly dim. 



I loved the original FT03 and still do think it’s a great value large format thrower. The mini shares a lot of similar features and somewhat similar performance but overall I am just a bit less excited about it. The Aux LED’s here don’t do a ton for me, they are neat but not that practical. For the money if size isn’t a factor I would go with the larger FT03. If you want the smaller size it’s not a bad light if you want aux and onboard charging, if neither of those are important I would check out my review on the Lumintop GT Mini and consider it as well. 

Acebeam L17 Review (160,801 Candela, 1400 Lumens, Awesome Thrower)

Today I have a new compact tactical thrower from Acebeam. They boast that the L17 which easily fits in your hand will throw out ot 802 meters. It runs off an 18650 and features a Osram LED. Thanks to Acebeam for sending me this new model. Let’s take a detailed look.

Packaging & Accessories

The light does come in 3 different versions, a white or Green LED version both capable of 800 and 820M of throw respectively, and a Red LED version that’s capable of 460M of throw. T

The standard package is a nice retail box with a line drawing of the light and the LED lumen and distance ratings on the box. On the back side there is a lot of stats and detailed info, good for any retailer looking to sell this. Accessories that are included is the light with the clip and tactical ring installed on the light. It comes with a lanyard, spare button cover and 2 spare orings as well as the standard paperwork and manual. You also get a nylon holster that’s branded Acebeam that has a D ring and belt loop with a button. 

Acebeam offers a couple of additional accessories on their website that will work with the L17 but are not sold in the standard version. First is a 10A rated 18650 battery with microUSB charging and a remote pressure switch for only $10 which is a good price. 



The L17 is made from aluminium and is hard anodized in a flat black. In the tail is the e-switch for the light and it’s truly silent. The cover is a rubber boot that has medium texture that sits just under the bezel. Internally, the tail has a single stiff gold coated spring and then an additional contact to the inner tube of the light. Threads are anodized, square cut and smooth. 

There is a tactical ring on the body which serves as a cigar grip point, the lanyard attachment point and adds reinforcement/lock for the clip on pocket clip. Both the tactical ring and pocket clip are removable should you wish. It’s a nice way to add quite a bit of security to the clip without making it permanent. The body tube itself is plain and features no knurling, I would like to see a little more grip here or closer to the head. 

The head itself is glued to the body. The head has some decorative milling around it and it helps dissipate some heat. The bezel is aluminum and has some modest large crenulations for a tactical light. The lens is glass with a Carclo TIR lens inside designed to enhance the throw. 

Size and Weight

I measured the length at 140mm, minimum diameter of the body tube at 25.5mm, and maximum diameter of the head at 40mm. Weight with an 18650 battery is 196.9g,




You have a couple of retention and carry options with the L17. It does come with that nylon holster for belt carry. It’s a basic holster but does the job well. You also have that pocket clip. The clip is 1.4 inches from the top of the light so it’s definitely not deep carry. 

LED & Beamshot

Acebeam doesn’t specify which LED exactly is in the L17 only that it’s an Osram. I asked my contact for clarification and they said it was an Osram KW CSLPM1.TG which is a mouthful but good to know exactly whats in it. It’s a very throwy LED that Acebeam has put a TIR optic on top with a glass lens. It’s different looking than your traditional optic and this is designed for all throw. 

The result is a light that has virtually no spill, it’s all focused on the center in a tight pattern. The combination of the optic and LED choice explain the claimed 160,801 candela rating here at 1400 lumens in Turbo mode. Tint here is cool white but I don’t detect much blue in the beam. In my night shots it stands up pretty well to some of the competitors using different LEDs but this has a tighter more focused beam. I didn’t notice any PWM here.

Specs below are for the White Version I have. The Green version throws slightly further. 

  • Turbo – 1400 Lumens – 160,801 Candela
  • High – 370 Lumens – 42,025 Candela
  • Mid – 150 Lumens – 23,409 Candela
  • Low – 50 Lumens – 11,025 Candela
  • Ultra Low – 15 Lumens – 3,600 Candela


Heat & Runtime

I did all my runtime and heat tests with the supplied (optional) Acebeam 3100mAh battery that was sent. It’s a 10A battery so keep that in mind for what you decide to put in this light and choose something with at least htis rating. Total runtime was 4:35:00. In my runtime tests I saw Turbo last for 3:30 before stepping down to right at 50% relative output. This is also where I saw maximum heat at 64C (147F) so this definitely gets hot and that thermal protection kicks in to limit output. The light maintained this 50% output for a total of 1 hour before stepping down again to about 4% relative output. My advice would be if you plan to use this light on Turbo for more then once past step down is to wear gloves. It only takes exposures above 60C for more then 3 seconds to get 1st degree burns.



The L17 uses a pretty traditional and simple interface. When Off long press on the rear tail switch for ultra low (15 lumen), single click to turn off. Single press to turn on to low, long press to cycle modes. Double click to go to turbo, and triple click to go to strobe. 


I will say mode spacing here isn’t super common. Ultra low is 15 lumens and throws really well for not much light. Next is low at 50 lumens, Mid is 150 lumens, high is 370 lumens. Acebeam says this will go 410 meters. Next is Turbo the full 4500 lumens or 160,801 candella. 



  • Nice to see colored LED’s being offered here instead of just a filter. I could see this being popular with a hunter with the green tint option. 
  • Very tight and compact beam with great throw
  • A fairly compact bezel which makes this more accessible.
  • Silent Tail Switch & good vibration resistance.



  • The light gets incredibly hot during turbo before step down. Wear some gloves or hold the back of the light.
  • Big steps between High and Turbo. 



I can recommend the Acebeam L17 if you’re in the market for a fairly compact 18650 powered thrower with basically no spill. I am typically not a big fan of tactical lights but the UI on this light is pretty non-tactical so it works out well. 


This isn’t the light to take with you when hiking, or for EDC or for walking the dog to see right in front of you. It would be great for a security guard who was needing to point out a specific spot on a house or inspect something from a distance. It’s also just a lot of fun to impress your friends or significant other, it’s a lot of power and so focused. It’s probably the next best thing to a LEP light.
