The adaptors weremade a long while back by chiefwiggum and has not been produced since. I feel very fortunate to have gotten two of them that run the AA's in series, and cherish them dearly. I currently use them, one each, in a 2D and 3D mag. Now I have the power of a 5D in a 2D package, and a 6 in a 3 cell package, though shorter runtimes due to AA smaller capacity.
I love
whipping out the 2D and blowing away or matching guys with 3 or 4 cell lights. Gives me a chance to show off how I accomplish this. Of course I installed the apprpriate bulbs for the number of cells running them.
The 3D will now outthrow my SF G2, but the beam quality sucks due to the bulbs. Mainly because of the dark rings, makes it difficult to get a good "spot".
As a matter
of fact I conducted an experiment tonight. At work I have to make an offsite patrol of an abandoned building the company bought that used to be a K-Mart. Standing behind the building, there is barely any ambient lighting and it is dark at the far end, there is a wall that juts out perpendicular to the building at the far end. Distance is a good 75-85 yards.
Trying the G2, with batteries that have less than 10 minutes on them, it will light up the wall faintly. When you first hit the wall, you don't really notice much difference, but turn the SF off and on a couple of times, and you start to perceive the illumination of faint details not noticed without the light, i.e. wall's surface, creases.
Try the
3D with adaptor and it places a spot that is easily defined on the wall, and easily perceived by eye on the first shot. And that is with batteries that have been in the flashlight for several months, and have been exposed to the Florida heat that builds up inside of an enclosed, parked veicle, very high temps that can drain an alk.
BUT, the spot
is very small because when focusing the beam there is this one dark ring that all but prevents the light from creating a single, solid, focused spot. I think any mag owner knows what I am talking about.
So if
it was a situation were there are persons of unknown intent at the far end, I would be able to see them with the G2, but they could still very possibly be able to avoid detection if remaining unmoving and maybe laying crouched or prone. Also I probably would not be able to make out more than the most obvious details of their appearance or actions, i.e. wearing/not wearing a shirt, which direction they were moving in.
If it
was the mag set up, I would be able to see clothing details way better, and they wouldn't be able to "fool" the observer unless actually hiding behind some cover. And it better be big enough to hide all of you. Could more than likely be able to tell they were holding something in their hand too, though maybe not tell exactly what it was due to distance and lighting.
I would try the WriteRite remedy, but do not want to diminish any of the output I am experiencing.
I know that I could get some great performance with some great bulbs. Alas, I emailed flashlightlens.com and was informed that the bulbs in question are bi-pins, of no use in my stock mags.
