Whenever you ramp up or down and release the button it will blink once to indicate it’s using the 7135. It will blink twice to indicate it’s using the FET.
There is a little glitch/feature where if you turn the light off during these blinks, the switch light will stay off until the next time you turn the light on again. This is not documented. It’s just something that was noticed.
You can also go into to the settings to turn the switch light off on a more permanent basis if you prefer.
Wondered if it was a glitch, the button feel in general is pretty w4nk. Hit it from an angle and nothing happens, hit it too lightly from dead on and nothing happens.
I have two of these and the button is quite sensitive on both - could not duplicate your issue - tried on both. Might just be your light
For what it’s worth
There’s no green led on the S43 I received. I’ve done a factory reset. The red charging led works…but when finished, the switch just goes black.
I’m guessing I got a bad one? I would surely have liked that led in the dark, and to see if the light is locked or not.
Switch is the only thing I didn’t like, the press had to be firm and centred.
Try turning it on at the lowest level and immediately ramping up slightly and down to min and turning it straight off.
so anyones status ich changed into “sent”?
Why are you telling him this?
Btw, you can temporarily make the green light stay off just by turning the light off while it’s still blinking after ramping. There’s no need to be elaborate or go to minimum.
It does seem like your green led is not working. Try contacting where you bought it to see if they will do anything. Maybe they will send a replacement head.
Hmm, it sounds like the Green LED is not connected properly. They had to make a last minute change to the light to switch the green LED from the charge circuit to the driver so a lot of manual labor was involved. It is inevasible there would be human error on a few of them.
As was said I would contact banggood and see what they offer. If you know your way around a soldering iron it is possible you could fix it if you opened it up, most likely just a bad connection on a wire.
Yes, I’ve gone through factory reset and every possible menu option now. No green led to be found anywhere :disguised_face:
I don’t have a soldering iron so I’ll await Banggood’s response for now!
This is my first encounter with Banggood. Very swift and pleasant customer support! They will send me a new S43 :+1:
A friend has asked me for advice…he wants to buy a flashlight.
After analysis of requirements I decided that Emisar D4 would be a great choice, but a rechargeable D4 would be even better.
So S43 came to my mind….
I haven’t followed that light and know very little about it beside the fact that it has a TA-developed driver.
I did some reading, but not enough to really understand whether it’s a good pick….not that this is the most written-about light, but nevertheless the amount of discussion is large and I’d like to avoid going through all of it.
Would anyone mind answering a few simple questions?
If there are any problems known with the light?
What is the real output? I see some measurement of 3000 lm, OK. Others say 1xxx which I find pretty low for a light like that.
What is the overall quality compared to D4?
Is it reasonable to assume that this light will be reliable?
If there are any problems known with the light?
Too early to say

Too early to say. Astrolux lights in this series have had many early problems
There are not any known issues that I’m aware of. The built in charging rate is a bit low at 0.5A. It means it takes longer to charge, but that may not be a big deal for most.
Whoever said 3000 lumen is crazy. You have 2 different emitters and 2 different models, S43 and S43S.
The S43 with the neutral white Nichia 219C emitters should be about 1600-1700 lumen.
The S43 with the cool white xpg3 emitters should be about 2100 lumen or thereabouts.
Then the S43S is an upgraded version that can draw higher amperage from a battery. This might bump it’s specs up maybe 200 lumen more.
Thanks for the answers. That was enough to make me make a decision - I won’t recommend that light. The tipping point was reading about the inefficiencies mentioned in the review thread.
What is your budget? There must something else worthwhile that falls in your criteria.
Just got hold of the s43s and its pretty nice bearing in mind its a budget unit.
Some pics if anyone is interested. The turbo stepdown is better then the s42 and heat is better also probably due to the massive lump of copper.
i have a 18650 tube and and short tube as well.
Your friend must be a hard core flashlight guy to care so much about the efficiency. Does he also care a lot about driver efficiency? That may rule out a lot of lights, as well. 
300 PLN, so about $78 including cell and charger (built-in charging is preferred).
I recommended Emisar D4, it was my only recommendation truly faithful to the requirements (small, BRIGHT, very good quality). But since the person liked the idea of a built-in USB charger, I know he likes gadgets and he likes to travel - I also recommended Folomov EDC-C4 as its powerbank feature might be more valuable than the output.
ADDED:
Since he cares a lot about output and S43 doesn’t deliver, largely because of a major design flaw - I decided it’s not worth recommending. D4 costs $12 more (with shorty tube and 219C) and delivers 75% higher output. The person wants small weight and here D4 is better as well. The XP-L HI option may be interesting as well, if he wants D4 I’ll talk the LED choice with him.
ADDED: Also, it’s quite funny S43 output is closer to that of EDC-C4 that to that of Emisar D4….It sits half way between a boring work light and a flashy toy - in both output and features.
