This isn't near as impressive a collection as a lot of people have but here is most of my collection:

Left to right. - Top Row
Maglite 4D Modified by Fivemega. Has been quad bored to accept a 16aa pack of AA's for 19.2v. And a FM Bi-Pin socket installed to hold an Osram 64458 bulb for 10k lumens. Includes a Fivemega 3V-2 head and has been half moon grooved, polished and then chromed.
Maglite 3D Modified by Gensing. Has been quad bored to accept a 12aa pack for 14.4v. Has a custom bi-pin socket to use Osram 64623 bulbs for ~4400 lumens. But can also use reflecorized MR16 bulbs for increased runtime. This is a unique prototype out of the only production run that Ginseng ever did of about 40 lights. All the others were designed to only use the MR16's.
Maglite 2D Modified by Fivemega. It has been quad bored to accept a 8aa battery holder for up to 9.6v (less with dummy cells) with a Kiu Bi-Pin Socket. I've got quite a few different bulbs for this including WA1111's, WA1185's, and Philips 5761's. As you can see in the pic it's had a diamond pattern machined into the knurling and the head has been finned for better heat dissipation. And been re-annodized in HA3-Natural
All 3 of the D based Mag mods have metal reflectors and pyrex lenses to stand up to heat.
Next is a 1.75D mag modified by Fivemega. It's been cut down and tri bored and has a battery holder for either 6xCR123's in a series/parallel arrangement for 6 volts. or 3x17700's in parallel for 3.7v. It's been finned, grooved, and re-annodized.
Next is a 2C mag that I modified myself with an old LuxV LED, It runs on 3xXR123's with a spacer for 9v. It's still pretty bright.
and last is a 2aa Minimag cut down to 1aa by Modamag (I think. may have been Mac). Designed to use 1x14500 3.6v cell. It currently doesn't have any type of light engine in it.
