I´m interested in a black version with SST40 in 5000k.

I hope for a good heat dissipation, like with the Nightwatch NSX3 and NSX4. Unfortunately there is no start in low and no ramping.

Please with the option for a OP-Reflector for biking. The Nightwatchs have a very good light distribution with an OP.

What is yours Nightwatch NSX3. Is that with SST40 emitters? I have it and it with XHP50.2 and the beam is very floody. I was wanted also to use some of this multi emitter flashlights also for my bike. But I want to have little more throw. For now my favourite is SP36 XPL, it has very good hotspot with nice flood. I wanted to have something like that but in more compact form. So my wonder how this new Haikelite is comparable to EC03 with SST40. In my last light which I have SC31Pro with SST40 it is very good little trhower and it is very good for helmet light.

Yeah, you’re right. With the SST40 it has a nice range and due to the OP-reflector a nice side illumination.

Unfortunately the NS43 is no longer available in 5000K. For me it is the perfect lamp on the bike, also because it can dissipate the heat well.

Thanks for the codes. M4D M4X what is the UI of this flashlight. It is Anduril based or not? There is no such information in BG listing.

I just received a “delivery delay notification” from bangood. Are there any information available, when they will restock the HK4s again?

Now they list also using the 26800 size battery. Any confirmation of this?

Just received the HK4S awhile ago.

Apparently this is a 26800 flashlight.
By default, it comes with a short tailspring (really long body tube).
Using unprotected flat-top 21700 battery (eg. Vapcell G50 21700), or even a longer protected 26650 (Keeppower), the tailcap spring will not make contact at all with the flashlight.

With the default short tailspring, I could only have the flashlight make contact when I use a protected 21700 battery (I have one from Rofis MR30).
(unfortunately, I do not have a 26800 battery. I do have a 26700 LiFePO4 battery which I bought for ‘testing’ only — and just like the unprotected 21700 batteries, it won’t make contact with the default short tailspring)

Fortunately, the accessories package does include a longer tailspring, which means the short tailspring has to be pried out (I thought it was difficult to pry, but it pried out easily), then replace with the long tailspring. Now the flashlight works with regular unprotected/protected 26650 batteries or flat-top 21700 batteries. Now I wonder if just plugging in the long tailspring in the tailcap will have good contact resistance?

using these 4 different batteries to test if they will make contact with the HK4S body tube
(protected 21700, unprotected 21700, protected 26650, unprotected 26650)

notice there is a big clearance/gap when using unprotected 21700 & unprotected 26650 (short tailspring will not make contact on the battery at all)

using a protected 21700 will make contact with the short tailspring, there is still some clearance space (will probably fit the 26800 battery type, mentioned in the included manual)

difference of the default short and long tailspring (default short tailspring installed; long tailspring included in accessories pack)

forgot to mention, the positive side (head/driver) is a big copper button instead of a spring.

~~~~~~~

other note: it uses a somewhat old version of Anduril: – no 15-clicks version check – no factory reset – has manual/automatic memory mode toggle (estimated Anduril version is 2019-06-02) – has 2-level brightness when in lockout mode

Copper button? That's potentially bad - copper oxides quick if untreated, or scratched up. Hope it's brass, not copper, as they usually are.

I'm not surprised about old Anduril, but the 26800 thing is a surprise, guess for Martin too.

I'll add a bypass on the long spring, then it's good to go. I've popped/pried out many of these type of springs before.

For those not familiar with the 26800 battery. It looks like only one manufacturer makes it and it’s a pretty good battery. I use one for the Nightwatch NSX4 running 4-XHP50.2

Use the Olight magnetic charger.

I have old 26700's but not these new 26800's. Only found this one place to buy 1-2 on Ali, about $28 for qty 2 shipped, ~$16 for qty 1 shipped.

Any other place to buy them, possibly cheaper?

I have no connection or profit in this company. But these are the guys I got the 26800 batteries from for only $4.75 each. This section is probably 99% of what we here would be interested in. Some prices are much better than others some not so. I’ve ordered twice from them, once on a Tuesday and shipped the next day. One order on a Saturday shipped the next Monday.
