Review: Astrolux S1 3D Flashlight






Astrolux S1 3D 18650 Flashlight Review 



The people at Banggood provided me with an opportunity to review the Astrolux S1 flashlight. This is a flashlight which appears to be a replica of the very popular and highly successful BLF SE A6 flashlight. I've been a fan of the cigar shaped flashlights for a while. The Convoy S2 and S3's have been my flashlight of choice for many years. Other similar sized flashlights have appeared on the market with many performing very well. Then came the wonderful BLF SE A6, which was came about through the excellent efforts of those on the BLF forum. The design, component selection and excellent driver and firmware, all came together to produce an amazing flashlight. After having purchased the BLF SE A6 3D version, it quickly became my most favourite flashlight.

I was keen to test out the Astrolux S1 to see how well it performs and if it could outdo the original design. What I found was very impressive. Read below for more details.

Link to product at Bangood  Astrolux S1 (Not an Aff Link). Listed price is around $29.95

Overview

The Astrolux S1 arrived in a nice box containing the flashlight, 18350 extension tube and a small plastic bag containing the lanyard, replacement tailcap and two extra O rings. Basically everything one could expect here plus a few extras. For those who enjoy retaining the gift box you may consider removing the tape. I'm not too concerned about the tape, however I have read in the past people have had success removing it after applying some heat. The inclusion of the 18350 tube is a real bonus.

 

Below we see the BLF version alongside. The box is better presented as it’s without the tape, but we see the inclusion of the 18350 extension tube I the Astrolux offering. Otherwise the flashlights themselves appears very similar if not identical. The packet of extras is similar too.

The Astrolux S1 comes in multiple LED versions. The model tested is equipped with the #D LED, which is my preferred tint.

Quality and components

 The flashlight is a compact tubular design that uses the 18650 Li On Cells that fits nicely in hand. It comes with a fitted carry clip that can be removed.

The flashlight length is almost identical to the Convoy S2+, however it's slightly longer than the Olight S30. The flashlight can tailstand.

 Alongside the BLF SE A6 the dimensions are near identical. Visually the only obvious difference being the labelling.

The anodisation in the supplied flashlight is of a high standard. Very pleased with the quality of the anodisation in the head, body and tail. No imperfections found. The color is consistent too, being black.

Below is close up image of the XPL LED

 

Image below of the body with  the head section removed. The thread being lightly lubed and includes an O ring fitted.


 

One difference noticed was that of the spring attached to the LED driver board. The spring size is larger than that included in the BLF SE A6. The Astrolux S1 is on the left of the image below.

 Side by side comparison of the geads of the two flashlights. Both include an OP reflector. The LED plastic gasket differs between the two flashlights. Astrolux S1 on left, BLD SE A6 on right.

 Dismantled head and tailcap. Threads are slightly squared, not too sharp. Very nice quality.

Body tube shows even thickness walls.

 

Below is the 18350 tube. Orings are not fitted, however these are included in at accesory pack included with the flashlight. The threads did not come lubed.

Side by side there are some very minor differences between the carry flips. For me the larger wings on the end of the securing section of the carry clip were too large. In the image below the Astrolux S1 has clearly smaller wings which may prevent damage to your trousers, for those who like to carry the flashlight in their pockets.

My personal preference is to not use a carry clip on my pocket flashlights. Below I've removed the clip and fitted the 18350 body to the Astrolux S1. The inclusion of the extra tube is a nice little bonus without much impact to the price.

Alongside is the BLF A6 

 

The supplied 18650 tube in the Astrolux S1 measured approximatley 69.5mm. This is identical to the BLF SE A6. In the image below I have loaded both flashlights with a LG HE4 flat top battery which is 65mm in length. The end of the battery extends just above the edge of the tube. This is due to the larger spring fitted to the driver board. Longer batteries such as the NCR18650B with button top at 70mm in length are also ok with this flashlight.

 

Head of the S1 partially dismantled. LED board. Quite clean with good solder joints.

Tailcap dismantled. Easily achieved allowing easy access to those who wish to replace the tailcap.

Close up view of the switch

User Interface

One of the great features of this flashlight is the excellent firmware included in the driver. The image below describes how to navigate between settings/modes. The flexibility of the firmware provides access to a range of modes that meet most peoples needs. My personal preference being the Group 2 (Low – Medium – High – Turbo) with Memory activated. The modes are nicely spaced with the the ability to use turbo when needed to really impress. Turbo mode drops down to High mode after around 90 seconds. In that time the hed becomes noticeably very warm. Credit to Toykeeper for developing excellent firmware. below is the image that describes how to navigate between modes.

  

 

Current Measurements

The Current measurements were taken using a UNIT UT204 clamp meter with a 12AWG wire with the tailcap removed. Actual current levels will be lower due to the resistance of the tailcap switch and spring. The measurements below suggest that the direct drive performance of the Astrolux S1 is marginally better than that of the BLF A6. The internal components of the two torches are very similar. The only noticeable difference being the larger spring present in the head of the Astrolux S1. This may result in a lower resistance, thus higher tailcap current. The LED wires may also play a part here too.

On Turbo mode the flashlight head heats up very quickly. It is not recommended that it be used on high mode for extended periods. During the testing that resulted in the measurements recorded. The Flashlight head heated up very quickly, even 30S at these currents are not recommended.

 

 

Light Output

Below are my ceiling bounce measurements. This is a good guide of the total light output produced by flashlights as a method of comparison. The results I presented below have been refreshed from those I’ve included in past reviews. A new light meter was used and all measurements conducted in the same conditions. The measurements of the Astrolux S1 are very similar to those of the BLF SE A6. This isn’t unexpected as they are near identical products. Both results are very impressive given the small size of the flashlights. These results are measured on the highest output setting for each flashlight. In the case of the Astrolux S1, it’s the turbo mode.

Summary

I'm extremely impressed with this flashlight. Based on my findings I'd consider this flashlight a slight improvement on the excellent if not great BLF A6 SE model. The quality and performance of this flashlight make it a must buy for flashlight users.

Link to product at Bangood  Astrolux S1 (Not an Aff Link). Listed price is around $29.95 which represents wonderful value for such a high quality and performance flashlight.

Pros:

> Excellent Quality

> Great User interface

> Very High Performance

> Includes 18350 tube

> Improved carry clip.

 

Cons:

> Only available in Black.

Thanks for the feedback. I think it’s great value. It represents a slight improvement over the BLF SE A6, and as it’s being sold at the same price it’s slightly better vlaue as it also comes with the 18350 tube. The BLF SE A6 is also an excellent buy for those wanting the BLF logo. Both great torches.

Weird, are my eyes playing tricks on me, or is the lower right of the hotspot loaded up/extra bright compared to the rest? That’s really odd.

Great review. Thank you.

I do see in the pic, that the negative solder joint on LED board is NOT very neat. Probably adequate, but I would have to touch that up.

Is it ok if i’m using lower amp 18650 e.g. samsung icr18650 on turbo? Since it was direct drive on turbo, is it safe for that non- protected battery?

ToyKeepers firmware has low voltage protection, so it is safe to use non protected batteries

- Low-voltage protection will progressively step down the output at

about 2.8V, and the light will shut itself off when it gets below 2.7V.

As you say it’s not perfect but could be improved. I’ll not touch it up as it performs well.

Looking closer I do so what you are describing, That’s probably due to the angle at which I took the photos.

Thanks for the positive feedback guys. I was very pleased with the flashlight. If you have any suggestions on how I can improve the review quality pleas elet me know. I feel that I had too many photos in this one and not enough explanation. The review is very positive for reasons I honestly really liked the flashlight. I’d say the same for the BLF A6. My BLF A6 has a couple of very minor quality issues, one being the uneven walls of the 18650 tube and the other was the color of the anodisation for the tailcap which was slighty blueish. Otherwise an excellent flashlight. The S1 tested is an A6 without th equality issues and with a couple of minor additions or improvements.

“More Information: first … first ….”

That’s for values of “first” as an integer between 1 and 3, unless they’re claiming all they changed was the paint, right?

that’s in no way a complaint about the review — just took a poke at the manufacturer’s official description quoted from.
The original BLF-label light is the first with those features.
This one is — we can hope — an accurate copy with a different name painted on.

It seems all the hard work BLF specials require for the team members who make them possible and the flashoholic community that backs the sale of the first orders like a BLF kickstarter program is very much welcomed by the manufacterer for a follow up with a flashlight developed by real experts at the cost of no R&D and tested by flashlight junkies.

Checking Banggood the Astrolux S1 flashlight is not in stock but can still be ordered.

The coupon code of 8a955d reduces the price by 15% which drops it down to $25.46

Astrolux S1 (Not an Aff Link)

The coupon also works for the BLF A6 CREE XPL 1600LM 7/4modes EDC LED Flashlight 18650 which drops the price down to $25.46

Received my S1 yesterday from Banggood, and it was missing the 18350 tube – just a block of foam in the cutout area where it should have been. Not really concerned with it, since I mostly ordered it for the actual light and don’t have any 18350s to use with it anyway (yet), but it was a bit disappointing. Guessing it is something they add to the box before shipping the light and someone just forgot to drop it in there.

Reported it to their Customer Service with a few pictures, so just waiting to find out the root cause.

Edited to include the response…

Received an email within 24 hours offering to send me an 18350 tube. All good.

I received my S1 a few days ago, but I´m pretty indignant about what I got.

1.) Got one broken o-ring (not a real problem).

2.) The emitter is pretty much out of center.

3.) The UI is not working properly. The S1 was delivered switched to group 2, but when I switch to “med” there is “low” again. Another short click brings it to high. There is no way to switch to “med”.
Changing mode to group 1 and memory mode is not possible. Doing 16+ short presses does not lead to “blink blink”.

I do have the BLF Kronos X5/X6 and don´t have any problems changing modes with them.

I contacted the seller, but there is no response yet.

Is this a known issue ? And just in case, what can I do about it ?

Hi JPL, Sorry to read your issues. As you have done please contact Banggood and discuss the issues. I’ve not personally heard of the problems you describe, possibly someone else has who can assist with the query re the UI. I’d also recommend checking the thread on the BLF A6 troubleshooting http://budgetlightforum.com/node/41726. It may include a similar experience. I’ll do some checking too, and advise if I find a similar issue and answer.

Hi, I have lurked here for a long time it this is my first post. Having just ruined my dqg 18650 by trying to glue the switch back into place I have ordered the s1. Just wanting to see from other k members if they have been hit by customs charges. I got it for £18 ish. So hoping it may slip through

You can actually buy it for only slightly more on the EU warehouse right now, and then there should be no risk of issues with customs, and hopefully faster delivery as well. So, if they haven’t shipped it from China yet, you could probably cancel the order from china and get it here instead:

Same base price, but no coupon codes work there.

I also had some issues with mine, and it turns out it had a lighted tailcap switch fitted, this interferes with OTC.
