M4D M4X,
This may be off topic but do you think you could acquire a coupon code for the new G35 from Klarus!? The XT30R is running AWESOME but klarus just put on their website the finished product of the G35 and I am so stoked and dying to get my hands on one!
Thanks,
Shawn
i am confident i get something also for that one...
;)
Got my K01 yesterday. This is one gorgeous light. Initially over 1,500 lumens, settles in 30 secs over 1,400 lumens stock as-is on a EFEST or AWT 14500 cell.
It came in perfect condition. Has the same knurling at the copper X5 or Astrolux SC, very similar tailcap design. It's a very nice design, more practical than the SC in it's compact size.
I'm looking to do a triple or quad. For the quad, the TIR optics is a tiny bit too wide, so might try sanding it down. The stock MCPCB is a 16 mm DTP copper, but a 20 mm would fit and clear the LED wire solder joints better. If I were to keep the reflector, I'd switch out the MCPCB to a 20 mm one.
I'm not a fan of the lit tailcap when there's no simple twist mechanical lockout, specially with the low capacity 14500 cell, so it's fine for me.
Great deal on this! Thanks M4D M4X once again!
I hope a slightly modified triple spacer for s2+ will fit in there , to turn it in triple or quad .
Yea, that's what I'm thinking. I got a collection of spacers, so sure I can work with something. I also can get almost anything of aluminum at work. I could also get alum machined on special request - might cost me a light in exchange 
I just received my second K01, beautiful light. Been chatting with Macy at BG support, after several polite emails BG is sending drivers and boards for the tailcap illumination for me to install. I have found that when dealing with BG support, you just need to be polite, patient, and persistent, PPP!
I just made a K01 into a quad today using an S2+ spacer. I ground and filed off the narrowed part plus a bit, but I was using Khatod optics, which require about 5mm more depth. The bezel is very deep. The pill might go halfway into the bezel, but I doubt it. The reflector would be filling that space if it were there. With a Carclo optic, the whole optic might be in the bezel, with the MCPCB just below the edge of the pill. I had to remove about 70% of the bottom half of the Khatod optics legs to get them in. But, like I said, the Carclo are about 5mm shorter, and taper in more.
- no light in taillight, which was advertised at time of purchase.
- driver side spring broke off due to bad soldering. So light is actually defective.
BG didn’t react to my CS appeals (with photos) for 4 respectively 2 days until I opened an eBay conflict. Obviously, they asked for photo’s again, which I had sent already.
And obviously, they will offer a slight refund in BG points again ….
Keep you posted.
Phew.
Hey!
banggood already posted an appology for the tail light - pleasecontact Swi and she will send you the needed parts :)
you will get the new driverwhich also solves the broken spring problenm ;)
Cool. I look forward to their reply om my email :), thanks “Cleo” seems to be handling my case, so I’ll wait for het reply.
My replacement parts are on the way, it just takes some polite patience and understanding that english as a second language takes some time to work through.
Don’t like lighted, parasitic, battery draining, can’t lock it out, tail switch or the funky drivers that come with them, so I’m good! :+1: May I have a Black button boot instead!! 
I was literally in the shopping cart about to pay $40 for this, saved it to my wish list and came back to BLF only to find this thread! Thanks Martin! I filled out the form, eagerly anticipating my code so I can get this little beaut!
Dale - it's a nice little solid copper beauty for sure.
Experiencing some 4 yr old excitement in anticipation of a much wanted present. lol

Is there a jumping up and down jabberbox emoticon?

Mine showed up yesterday. Weighty for sure but nice. All are flawless. I actually like that the tailcap isn’t lit. If I change my mind I have switches I can change out.
The K01 looks nice, but it’s a 14500 light in a body bigger than some 18650 lights. It seems too big for its cell type. I’m still hoping to get a truly small 14500 light with a BLF driver, or revive the brass 18650 with a BLF driver and decent emitter.
Love brass. 18650 and blf.
Got it some days ago
It was DOA DWP (dead when packing)
Where is the quality control?
I had to heat the iron

However, thanks Martin!
