Magnet pulls on the internal spring,battery and my fenix clip (might be the only reason it works) through the alu (insane power for their size), but you loose the keyring hole... but the fenix clip I use on my light has also a hole where a split ring could be applied... not the most elegant solution, but doable in a pinch. My keychain is reserved for the DQG ... I use the Brinyte as small clip-on mainly. It is a single magnet with 3 mm height 10 mm diameter... I got it on Ebay but shipping took forever ~65 days. China Post is horribly slow these days.
Hm. I've spent the past hour looking for a good deal on eneloops and chargers. Too much choice. Fast or slow charger? Multi-format, or Ni-mh dedicated? This looks ok, but I'm always happier with an expert recommendation: http://www.ebay.co.uk/itm/UNiROSS-SPRINT-90-FAST-CHARGER-8-x-AA-SANYO-ENELOOP-/350303251816?pt=UK_ConsumerElectronics_Batteries_SM&hash=item518fb36d68
Not trying to wriggle out of my duties here, but is there much point in doing the run time test on alkies? Or should it wait til I've got the eneloop thing sorted? Thinking of your previous post, kreisler:
"The driver of the power LED lights demand 2.0A and the Alkaline provides 1.0A only. Result, light dims already."
Should have got myself sorted with eneloops before now, just never seemed to get around to it..
please no test on Alkalines, the cells simply cant provide the current which the driver demands, so performance of the light will be surprisingly dull :)
will check the Eneloops ..

i understand. since i luv accessories i should get such a magnet too BEFORE i decide to install and use it or not :D i guess you found them with FREE shipping ;)
i will take measurements from the LD01 and the Lumintop Worm SS. no pic Vectrex? :)
--
is this where you got yours from?
EDIT: i've measured the Tank E09. It's tail orifice (for the 10x3mm neodymium) is: 11.00x3.00mm. Perfect! True, the keyring hole would be inaccessible then.
The Worm's tail orifice is: 11.00x4.81mm so there would be an air gap of almost 2.0mm between the surface (e.g. refrigderator :D) and the magnet. i am not sure if this gap is bridged by the attractive force of the magnet :? (keyring attachment gone too)
the LD01 would be similar to Brinyte
No cam available right now... maybe tomorrow
These ones from the bay of E's, but shipping was slowest of slow... better try your link.
The brinyte is as close as it gets to a perfect clone of the LD01 from pictures I saw on the net. Somewhere where even side by side pictures, but can't find the bookmark anymore.

the ebay seller sells (5,6,7,8,10)mm x 3mm disc magnets, so would you believe that a smaller one than your suggested 10x3 is strong enough too?
keyrings (split rings) are magnetic too, so maybe keychain carry with split ring(s)+magnet is not the most practical idea. the magnet force would not let the split ring swivel, tss.
10x3 is optimal you think -- not too much strength? (yep, would love to see several pix as illustration. my hirn is too weak to imagine the beautiful fit hehe)
Will try to upload some tomorrow... I would be worried for bank/credit-cards... I will not install them permanently... too strong. I will use them for car/motorcycle repairs when I don't have a headlamp with me, or when I need a fixed light source. They are cheap ... so if you don't like them on your lights... they make great refrigerator magnets.
this is a convincing argument, thanks!! even a 5x3mm would be too strong and also mess with the splitring(s). i should regard the magnet really as accessory only as in your great example (work, repairs, vehicles, ..) and not carry it on the light all day long (the DQG Tiny II has a magnet. cant wait to see the DQG Tiny III sample on cpfmp!).
for work purposes, i do have my gorillapod with magnetic feet. it holds 20mm diameter torches (1x AA) very well and bigger ones (1x 18650). it's accessory too.
Finally i have understood what the magnet is good for: not for everyday carry and permanent installation but for sporadic application in very rare situations ( work ;) )
Am going to place the ebay order now for 10x3mm. that fits nicely into Tank E09, Fenix LD01 and Worm SS. ... okéeee..
EDIT: just ordered the warhammer neodymium 10x3mm!!
I'm not that fond of Uniross chargers in general - quite a few of them turned out to be battery cookers as they missed termination.
This one is decent and not expensive.
A pack of 8 eneloops
and the above charger will come to less than the eBay deal. And has (IMO) a better charger.
found it. my contribution went herein:
Thanks, I'll check out the links. At the moment I'm stuggling to upload some pictures. Had it all done, tried to preview, and for some reason it all disappeared! 
Talk among yourselves for a bit. Oh, you have been :\
while talking, we waitin' for ya! :p
No, not letting me do it. Maybe too many pics at once? I can't make the image URL/tree icon method work, so I've been trying to copy/paste the pictures themselves direct from Photobucket. I'll try one at a time. In the meantime I'll try to answer some of kreisler's earlier questions.
Hotspot is about 18cm in diameter at 1m distance. Spill diameter, including hotspot, is 1.2 M. There appears to be no doughnut hole or beam artifacts, though to be honest I'm not sure my eye is attuned enough to recognize these yet. Beam has a Saturn ring outside it, and appears slightly lopsided (off centre emitter?) Let's try just one beamshot pic.
My DQG Tiny II has a glow dot... for the same reasons... wallet and keychain are often in close proximity how I carry them
System seems to be struggling with the pics. Are they too big, maybe? I'll try a couple more. If this works, here's the Brynite with its new friends
Thanks to a very well placed notch machined into the tail ring the Brynite can tailstand even when attached to the keys
I wonder if you have a different type of anodization, as I can already see same silver shining through the red ano... my black one doesn't have a scratch from 2 years usage. I remember that I read somewhere that HAIII has to be black and every colored ano is Type II max.
This shot shows how the sliver of aluminium retainer is already starting to erode 
Here compared to G10 on the right
Here from about 30cm away. Shows the beam pattern and lopsidedness a bit better. Sorry to do all this one at a time. It's definitely the images causing the difficulty. Each post is taking about a minut to upload.
If you would use a very short nylon strap or thin paracord... might be easier on the aluminum.
Hm. It's an idea. Problem I see with that (as I'm sure you've thought of as well) is that the aluminium would soon wear through the cord. How does it work on your DQG? Must have a stronger anchor point, yes? And you're quite right about the red 'ano'. Looks nice, but somehow doesn't feel very resiliant. I get the feeling I could probably etch my name into it with any sharp metal object, though probably not quite true.
