KC1 keychain light is available now

Well, sort of. There's been some posts on how to do it on Windows, but TK doesn't do Windows - so her source code setup is for running on Unix/Linux. I am using the Windows based tools for compiling and linking Anduril but I have my own modified version. There's definitely better threads to post this on - we are kind off topic here.

This one would be a better start, not sure if it's the best one: https://budgetlightforum.com/t/-/47204

Sorry, I forgot with the carrier Hank uses you won’t be able to track it with 17track until the package is handed off to the final delivery carrier.

Was it shipped by 4PX? What does it show when tracked from them?

Yes it was by 4PX, it indicated “HK / Hand over to airline” for the last update on the 4th of April.

Mine arrived at the HK airport the same day, and it made it to the USA 3 days later. I received mine on the 17th of April. I live in Florida. The package was handed off to DHL and then USPS. I did have one package from 4PX that was never scanned or there was an issue in their system and it just arrived with no tracking. But most likely the delay is related to COVID-19 and stress it has placed on the shipping industry.

Hank, will you be restocking the D4V2TI blue swirls version?

I figured it could be very likely the case, I was just curious if anyone from Canada had gotten theirs.

Most of the orders from China to the US/UK/DE are shipped via special service which take about 2~3 weeks to arrive.

But there is no special service to Canada, thus we can only use Singapore post, while Singapore post shipping
time depends on the airline service, and since most of the airline service has been canceled due to the virus issue,
so, almost all the orders to Canada are stuck at “hand over to airline” status for weeks.
Once the order is shipped, it’s out of our control, we kindly ask you to wait longer.

Thank you for explaining and the link.

This is very extensive and interesting but I was hoping for a way to just make config changes to the latest Anduril as published by Toykeeper. For instance, to change switch LED brightness or turn them off or whatever. This would be very interesting, if it were possible.

Hank what tint bin of SST-20 4000k is in the D4SV2 being sold from the US Warehouse? I would like to buy one but it would need to be FA3/FD2 tint. If so, I will order one. Really enjoying the tint on my KR4. Thank you.

Noctigon K1, SBT90.2 version is coming, 4500lm, 420Kcd, 5A constant current.

:+1: I guess this uses a version of the driver from the KR4 with linear regulated current and direct drive mode. 5A regulated current works well in this situation IMO because that is nearly 1 hour mode which I find is a useful duration.

Every other flashlight purchase has been put on hold :smiley:

A K1 SBT90.2 is happening. Nice!!

YES! This makes me so happy! Thank you Hank :smiley:

Ooh, nice!
What price range do we need to save up for?

15W gets 4500 lumens? I thought the 90.2 was only a 3V led?

djozz’s text Luminus SBT-90 gen2 5700K tested (SBT-90-WDS-F72-SA600 SA-H4, from Neal)

I guess it’s up to 5A constant current plus FET for the 4500lm, like the KR4

I wonder what kind of power we’ll be able to get out of a 30T with an SBT90.2

Well, i suspect some error margin in Djozz’s test since the Acebeam K75 is rated for 6300 Lm, Chibim tested it on 1Lumen.com and measured 9A.

Is there a datasheet for the 90.2 somewhere or do i need to use other search terms?

I’ve seen the k75’s sbt90.2 tested as 4800 lumens by several testers. Grin pulled the driver and tested 28.7 amps. They didn’t even rate the GT90 above 5000 lumens.

Acebeam scams the specs, as do many.

Yes - the only way to get 4500 lumens out of a SBT90.2 is very high amps, so yes - the driver is FET+5A regulated. Also if you compare to an Astrolux FT03S, keep in mind Astrolux scammed the throw specs as well - gotta check the FT03S thread and check the real #'s BLFers got. So the 420 kcd Hank is reporting looks pretty darn good. Still hoping the 420 kcd is conservative though.

The FT03S is definitely FET based, so if the K1 beats the FT03S, then yes - must be FET+5A.

Probably the K1 SBT90.2 will have stock high qual springs, so bypasses should still give you an amp bump. It gets insane trying to pull 20-30 amps from one cell, so that's the biggest bottle neck. With triple XHP50.2 3V's on one GOLISI cell, very hard to break 30 amps, then it drops like a rock anyway. Would be great with a 3P 21700 setup - that would be my ideal SBT90.2 thrower with 3 40T's.
