Bro, is that you in the vid? 
I have the “cousin” Haikelite HT50 (quad G50 LEDs, presumably known as the yingding 5050 here in BLF) and i am not sure if there are any big UI differences, apart from mine not having smooth UI ramping but only having 4 stepped levels.
From the Haikelite TB pages, both lights need double click to access Turbo mode, smooth ramping on the HK90S only brings it up to 2k+ lumens. On my HT50, there is a marked difference between High and Turbo levels, as with all other budgetlights, eg Sofirn Q8 Pro with Audril 2, etc.
For those who can read chinese
HK90S
https://item.taobao.com/item.htm?spm=a1z10.3-c.w4002-24331852551.12.e34c17fd3fooJN&id=670431291471
I don’t have the JKK90, but i do have the JKK76……not sure what are the differences in UI
There is mode memory, and if the last mode is in Turbo and you switch it off, you will be in Turbo mode the next time you switch it on.
You cannot do that with the Haikelite lights (not in my HT50)
But one thing i’d notice is that the ground spill from the Haikelite HK90S is significantly weaker than the JKK90, absolutely no doubt. That spill intensity difference might be as much as a 2500 lumen level on the HK90S vs a 5000 lumen level on the JKK90.
Again, just guesses on my part……even a ceiling bounce on a phone’s light sensor + any app from Google playstore would give more info when the HK90S and JKK90 compared and also with other similar 5-6k lumen lights.
Just that my suspicion is that the Haikelite HK90S is not set in Turbo, just High
Unfortunately it might turn out to be the case that HK90S’ G90 indeed is not driven properly, though not very likely.
My HT50 with G50 appears to be driven ok and performing to the claimed specs, maybe the throw might be a little lower than the claims but it’s not out of whack.
JKK90

JKK76

And of course, like what it was mentioned in the vid, the HK90S is a smaller head diameter light. 60mm vs 72mm.
Just an illustration explaining what i mean regarding the spill mentioned in my post above.
The camera seems to be in auto exposure mode for video unfortunately, but the exposure levels seem to be pretty similar. In fact i’d even say that the JKK90 is a bit lower in exposure (look at the night sky for reference)
For sure the spill on the JKK90 is much high in intensity (more lumens from the LED, pure output).
Is this due to the HK90S not being in Turbo mode while to JKK90 is switching on in Turbo, or is it due to the HK90S G90 not being driven properly, or that this particular LED cannot perform, that i don’t know.
I just know that the G50 version (Yingding 5050) is alright to own and is in the ballpark for the lumens and throw (cd) numbers.
HK90S
JKK90
tldr - there is a good chance that the 2.8k lumen High mode is compared with the Turbo 5k lumen mode on the JKK90.
edit - just played with my Sofirn Q8 and some lights. Actually i just found out that similarly for my Sofirn Q8 Pro (audril 2), there is no way of accessing Turbo mode with just 1 click or in just 1 step. Of coz the vast majority of us know that as it’s already intuitive in a way. It’s so automatic for me and most of us that we don’t even really process this thought.
Mine won’t double-click to get to turbo. Tried many times.
Oh indeed it’s your video……
Unfortunately, ramping/stepping up wouldn’t get you into Turbo level, just High level. 
Same for my HT50. I believe you definitely know how this works for some lights………
I know the vast majority don’t read chinese, but turbo is accessed via double click in the instructions for HK90S (TB link above). You can do this in any of the normal levels or from OFF.
And from Turbo, double click again to get into the notorious SOS and double click again into strobe. I presume you also cannot access SOS and strobe too?
As per instructions on the webpage
There are small differences in UI between the HT50 which i have and the HK90S, for my HT50 there is only strobe and not SOS. HK90S has both SOS and Strobe. This is also mentioned in the HT50 TB webpage and product instructions.
And for your lockout “issue”, it gets locked out with a 3 seconds long press in OFF mode. You can unlock by mechanical means of twisting, or you can unlock by a 3 seconds long press in Lockout mode.
Idea : I’ll try to contact the Haikelite guy on Taobao (sole proprietership one man operation i think) via TB messenger app for ya and see what is happening and if he can help. He does answer on the TB app as i have asked him stuff before….though now with his new HK05 pre-order going on (nearly 700 orders in the past week!) i think it could take some time.
Also, there is one more thing that you can do. Ceiling bounce both the JKK90 and HK90S. Eg if the JKK90 reads 500 lux raw value and the HK90S reads only 300, then we have our answer. Ceiling bounce, not trying to read the hotspot intensity.
If you have a lumen tube then that’s even better, but that’s not necessary for these 2 thrower lights and in this context.
Mine doesn’t go to turbo. I will replace the batteries and try again. But the lockout bullshit feature is for the birds and does NOT unlock with three presses. It’s so easy to accidentally trigger…yet another reason why these drivers are trash.
Yep, i know what you mean by UI trash. The UI is still usable of coz, just not really friendly to use.
My HT50 electronically locks out when you are in turbo and then long press 2 seconds. In output modes 1 to 4, long press is fine, that cycles through from 200 lumens to 2.8k lumens. Like….WTF man? Why not stick to the proven 4 short presses for lockout? My Haikelite HT50 also uses 1 second long press from OFF position to enter “moonlight” output mode of around 50 lumens?
So definitely mistakes can be made.
Another thing is that my Amutorch DM70S and JKK76 both switch off with long press, so occasionally i do make the mistake of locking out my Haikelite HT50. I do use the Amutorch DM70 and JKK76s pretty often in real life so that long press to switch off is now like second nature to me.
Haikelite’s boss replied, really need to double click when the light is switched on to enter Turbo. I asked him if the top ramping output setting is same as turbo output, he did not answer that directly. But double click when the flashlight is switched on is confirmed. He also said that the HK90S and HT50 UI is a bit different, which we know of course.
I also made a vid regarding double clicking speed, see if that helps and to confirm that we are on the same page regarding this double clicking thingy. Mine is 4 stepped output modes, double click to get into turbo, and then double click again to get into strobe.
ps. Note : Mobile phone cam cannot lock into AE/AF lock in video mode, i activated it and it shows AE/AF lock, but it gets disabled when the recording starts. It works for taking photos though. But you can sort of detect the change in output levels, that is what’s important.
These HT50/HK90S lights don’t need particularly high amp cells to operate….i mean they are just 5000 to 6000 lumens output and we are talking about 3 and 4 * 18650 cells, the emitter efficiency shouldn’t be that overly bad. Of course for peak performance, i use my Vapcell P26A (around VTC6 ballpark), but my Sofirn 3000mAh is just a small 5% drop in output on the meter, which our eyes cannot see even with a direct A-B side by side comparison. Even my 10 year old cells can operate the light and kick into turbo, just not optimal turbo output.
So i believe changing the cells isn’t the solution as the solution is really about kicking into Turbo mode with a double click user input that’s recognised by the driver, but it never hurts to try.
BTW, it just occured to me that the boss also asked me which grouping is the light in, ie stepped mode or infinite ramping mode.
(the first message he replied at 20:39)
Can you try to get into the other grouping by clicking 3 times quickly when the light is switched on? It can alternate between the 2 when it is switched on.
Then try double click to get into Turbo setting in the other mode. Not sure if this would help.
The light has never come out of ramping. No amount of playing or holding down works.
He just sent me this image, seems to be claiming that it is Audril (1st version). Of course whether or not it really is Audril, i don’t know.
See how you’d troubleshoot it, as the things you tried doesn’t seem that the driver for this HK90S is programmed with Audril?
He sent other images but is basically a summary of 2, 3, 4, 5 etc clicks, in chinese……so won’t be posting here.
Wonder if there is an Audril factory reset, if that works that is…… as if the firmware is already messed up then it’s tough esp if the innards are not accessible and/or you do not have the stuff to flash it. Definitely not for the non-DIY crowd like me.
I am wondering if anyone else reading this has any additional ideas. I’m just a regular flashaholic and buyer of whole lights.
Basically a light that i stuck in infinite ramping mode, and the manufacturer fella said it is Audril.

This is, of course, assuming it is actually andruil. There are tons of resources available online on the functionality of andruil, but from the videos I’ve seen from OP, he is already not fond of this firmware to begin with. I hope he can get this sorted and his light set up in a way that he can tolerate or get a refund (seems less likely tbh).
