Is the battery tube compatible with H03?
I like the older model much more.
Ordered a H04 RC Mini for AU$57.77 delivered. 
I don’t think there is any difference in the threads between the H04 and H03, they don’t sell the 18350 tube separately though which is a huge bummer.
It’s listed as being 45 grams excluding batty—only 1 gram lighter than full length tube. I guess most of the weight is saved with the difference between 18650 and 18350/cr123.
Seeing as my H04 is already lighter and almost as small as many other 18350 headlamps, I don’t see much advantage to going smaller. But I can’t say I wouldn’t want a shorty tube for it! It doesn’t look like the sell the tube only though.
I like the size and weight reduction (like you said mostly due to the 18350 lighter weight), here with the Astrolux S1 18350 tube :
That little Mini is just the thing I have been looking at as a back up for my ArmyTek Tiara C1 Pro (I'm on #2; the first one failed). I was wondering if the flip-up diffuser feature was handy or just a gimmick. Now I know!
So I got two in the mail, reflector and tir version. I’m sorry I didn’t get the F version - there are subtle design changes to it. If you look at the pictures new models have a spring inside to hold it closed ao no more rattle and the light reflecting problem is easy solved with a bit of paint, nail polish or thicker tape.
I have one on the way also. Saw them a week or so ago.

Just ordered an 18650 H04 myself! So the S1 18350 tube fits without issue on the H04??? I just happen to have one of those 18350 tubes just sitting around… 
I asked Skilhunt whether they would sell tubes alone….they wouldn’t. 
Yeah on reddit KillZoneflashlights said they asked for short tube separately but skilhunt preferred not to sell them.
I mean I get it they don’t want to sell something that need some effort (strap wrench to unscrew the glued tube) to use. But they could just stop gluing that tube in the first place…
I unscrewed both H03 and H04 easy with no tools, just my bare hands. There’s some glue but not enough to make it hard to open.
Then again, I do a lot of deadlifts 
selling a complete flashlight makes more money
Whey sell a few $ tube when they can sell a 40ish $ flashlight?
Because in some cases the would get a few $ instead of 0.
That’s my case and I’m sure I’m not the only one who rejects the offer of buying a battery tube for $40.
That’s true, I’d also rather buy tubes than new flashlights but hey; two is one and one is none and now I’ll have four of them.
No red led?
If it doesnt have red I have to grab another light that does. No point buying this light. I use red every night as an anti-trip and fall light in our offgrid cabin. Deep in the woods and very dark at night.
I find red light extremely annoying and never use it, there’s low modes for that.
Its a good night light that wont disturb your sleep like white light. Its also good to enter chicken coops as the birds cannot see the red. You can trim their wings at night without having birds flying all over hell. I could go on and on but red works best. I dont want white blinding me at night.
Ever wonder why military runs red in ships and subS
