I ordered this host from fasttech
HTML http://www.fasttech.com/products/0/10002463/1277301-convoy-l2-diy-led-flashlight-host
It turned up today, roughly 8 days in transit.

The quality is excellent but I think the driver options are
going to be limited.
I'll flesh this out later but I'm planning on an xp-g2 @ 3a for
now see how I like it.
Ok its built up now. I used this driver
HTML http://www.lck-led.com/constant-current-driver-board-modes-p-501.html?cPath=37_135
a 21mm contact board and a 20mm xp-g2 3d tint. I also tested an
mtg-2 for fit in the reflector, its an option but the driver
choice is limited, I didn't power it up so I cant report on the
beam, but I may try it for interests sake.
The headlines, it easily out throws my fandyfire stl-v6, no
small feat to be fair. And all that with a lovely neutral tint.
On with the pictures.

5a board simply wont fit.

3a driver test fit, a contact board was added, screwed down with
the retaining ring and the star was lapped then soldered,
thermal diamond liquid added them screwed down (I like this
host). I used the supplied xm-l centring device to eliminate
some awful rings and it now has a lovely beam profile, I'm very
happy.
I shall take beam shots another night, I need to tidy up the
living room and do some in depth playing I mean testing.

That's a lovely looking host Graham. Every convoy light I have
seen so far has been great and the build quality seems
staggeringly good.
I'm off to find the specs on that host lol, I can only imagine
how well this will perform with an XP-G2 @ 3A it should be a
monster.
De-Dome or not to De-Dome that is the question

I'll not be dedoming the emitter's I have here, their 3d tint
so neutral enough, I may get a cw emitter to flow onto a
sinkpad if I like the beam and fancy a dedome, its all a bit
experimental. One thing I do like, the reflector is threaded so
you should be able to get correct focus fairly easily.
Specs are 62mm ar lense, 60mm reflector, option to build as 1 or
2 18650/26650, 2 sleeve's are supplied, my only bug bear is
the limited driver cavity, it 20mm by 12mm deep, they should
have made it 24mm by 20mm deep and supplied a contact board,
this would have provided much greater driver flexibility. For
instance I am aware of a 3 - 18v driver that gives 3a to a
string of xm-ls or 5a to a single emitter, I really wish that
driver could be fitted.

I dont know if you know how to use a lathe gords but if you dont
book into a tech school and learn. Send the Mrs out to get a
fourth job so you can spend productive time in the shed modding
lights. When drivers dont fit or you want to add batteries etc
you can make it happen. Love the host your using but it's a bit
expensive for me. It would make a good comparison for the
Defiant 3C. I dont know if you have seen it but I have posted
night shots of a XP-G2 in a HD2010. It would be good to see how
this host behaves with this LED. I have no experience with the
driver you linked to. Again it would be interesting to see how
this performs. Running an XP-G2 at 3 amps though I would suggest
a copper star at the least. Looking forward to seeing the result
of your build. Cheers.

I'm not a wizz on a lathe but I can shave lumps of material
away, the only problem here is that there's not enough material
to face off to fit deeper drivers, you'd need to machine a
housing for side clicky and driver then screw the body tubes in
and make a blank tailcap.
It is a very nice host and I am taken with the light, this
example of the driver is very slow to mode change but I can live
with that. I do agree that a sinkpad needs to be employed, once
that's done there's a resistor mod to bring the current up.
How does the xp-g2 work? Very well, I'm very very pleased with
it. I'm actually bored of xm-l based lights as I have enough,
I'm liking messing around with different emitters to get
different results, its very throwy, easily beats down my stl-v6,
along with it being 2 x 26650 (my favourite form factor for walk
around lights) I'm dead chuffed with it, it has a useful amount
of spill with out being to blinding, I also get a nice tint into
the bargain. If I'd bought a functional example I'd definitely
be considering swapping out to xp-g2 now I know what the results
are, I'll try to get some beam shots tonight even if their only
white wall shots.

It sounds like we have more in common than we realize. I love
the little XP-G led and have used it a lot in builds and mods.
Your first paragraph was good. Get into it. When things dont fit
the old grey matter gets a good working out. Cheers.

I showed wifey this comment, and it brought on a grin and a
swift kick to the shins.
;)
I do suppose it's our own fault; we did allow them to
vote/drive/etc...

I do have access to a machine shop, just not the time at the
moment with everything else going on.
I've got to be honest, I'm loving the xp-g2, two builds, both
pretty damm sharp throwers in their respective class of
reflector. As I've said before, I've got so many xm-l based
lights, I'm a little jadee with them tbh, different emitters or
hosts are keeping me interested.
I'm also hoping to continue with the other project tomorrow, I
suspect I'll have some waiting time so I can carry on scraping
out the threads. Hopefully the battery carrier will turn up in
the next few days.

beam shots..... ok their phone camera shots but give an idea.
All wall shots are 4m from the wall.
convoy l2, xp-g2 3d @ 3a.

simple outdoor shot, the camera cant pick up the lights outer
reach, ill try to get a daylight shot to see if the furthest
building is visible, I cant wait to get this somewhere without
all the light pollution.

between the two street lights about 100 - 200 yards futher out
is a pub, it has no problem lighting said pub up.

That looks absolutely outstanding Graham. I'm really looking
forward to the longer range shots, and even more-so when you
manage to find a higher power driver that fits.
