Skilhunt H03 short battery tube lighweight mod

Sigh…

Alright, should have checked this before…
So it turns out the Astrolux S1 short tube fits better than the BLF A6 short tube.
I ordered the A6 short tube for this Skilhunt mod, but i have a Astrolux S1 shorty too (but i use a S1 18650 tube).

Mystery solved…

Ya, which tubes fit what has been a circus ride trying to follow:)

You apparently need the S1 tube for this mod. :exclamation:

I don’t know why I have been on a nichia kick lately, cree still has perfectly decent stuff, thing is I ordered a bunch of 19c and 319a’s . I don’t mind warmer tints although I really been liking 4000k I would certainly not mind a warmer tint for a headlamp where I’m often using it to work up close (warmer tints are much easier on my eyes, I guess i’m weird). I actually like warmer tints better, on high levels I always thought warmer tints held cri better but I thought it must have just been in my head so thanks for clarifying!

So you would recommend getting an XML2 instead then? If Mtn has them I might be placing an order with them soon.

Thats great news, if my nichias ever arrive from china I’ll probably try one in there too! What did you use for a spacer though? Probably not something I have around and I will need to order.

Awww man now you tell me. Now I just wasted $2 lol. Not having any 18350s yet, can you explain to me how the S1 tube fits better? My A6 tube I ordered seems to fit really well after grooving it for an oring (used a $1 file from china freight) I don’t understand the be careful cause it has short threads comment, is that because I don’t have an 18350 to throw in there?

Thanks!
Also no one commented on how sung that headlamp band is? Can you still adjust the headlamp one one hand or does it require 2? Is there a better option?

One hand is enough the long tube is quite easy to twist the short rotates with a decent grip on the head

I just found out myself…

Threads fit better.
The threaded ends of the S1 tube have the same diameter as the original Skilhunt 18650 tube.
The A6 tube is 1mm smaller diameter.
The A6 tube is also 2mm shorter than the S1 tube.
Protected 18350 would be a problem with the A6 tube.

I don’t now, maybe Banggood sent you the S1 tube.

Okay, let’s post some pics then:

I had thought that I finally figured out what tubes fit what. So just last week I ordered 5 a6 tubes for the h03. Aaaah

I ordered the A6 tube and they fit protected cells, maybe they really sent me an S1 tube?

I also see your S1 tube looks like my A6

Can you give me the bore, outer diameter and lengh of your S1 tube?

Okay, let’s get the callipers. :slight_smile:

Inner diameters are both 19 mm, outer diameters are both 24mm.
Diameter of threaded sections S1 is 22mm (same as Skilhunt), A6 is 21mm.
S1 tube is 37mm long, A6 tube is 35mm long.

Let’s hope they send you the wrong ones too…

So the threads on your A6 tube were lose due to being 1mm narrower? The A6 I ordered the threads feel tight, and it looks exactly like your S1 in the pic. I dunno if the S1 and A6 look the same anyways? For now both the A6 I ordered from bangood (if that is even what I have) is fitting perfect and threads are tight and smooth so I’m not sure what could be improved anyways, unless when I get my 18350s they don’t fit! :slight_smile:

My 16340’s fit in it too after I did the spring / magnet mod, they are the same capacity as most 18350s anyways, and are high drain so they can push the LED just fine in turbo. Probably save some weight over the 18350. The 16340 (RCR123) battery is loose in the tube, but apparently under enough tension that it won’t rattle or misbehave anyways.

Jut to be clear, this is the tube I ordered, it looks like the one in your picture.

Also the headband is $3, but shipping is $9? Hmmmmm anything cheaper that will fit? That’s 1/2 the cost of the headlamp!

Ok to make it clear I ordered the A6 tube but in fact I received a S1 tube

It is 37mm long and still a tight fit for protected batteries.
Also the longer threads are needed for a good fit, no sanding down needed

First post edited

Man, how did you get the head loose? Either mine has more glue or I have little girl strength. Don’t want to mar or deform the tube using tools, but I can’t get the damn thing off by hand…

Its not possible by hand, you need heat and tools
The tube is a lot more stable than you need to open it

Is it possible to get the reflector from the R model separately? Would it fit the H03 instead of the optic?

Probably not…

Yes.

Thanks, can you do me a favor and measure the reflector?

Do you think this one from fasttech could fit? https://www.fasttech.com/products/1617/10001275/1209600

I’m not gonna take one apart just to measure the reflector, but when i do take it apart (i plan to put Nichia 219C in them) i’ll report back to you.

I’ve been looking for a reflector as well.
