With regards the Maglite 7C.
As best as I can recall, Maglite Brand, by an American John Maglita, his company in my view, started the long torch revolution.
Theirs, was a torch that was robust, well thought out, and engineered.
Maglite 7C Torches, can be easily turned to a Flood, by simply twisting the front bezel.
Maglites, used a Lexan clear plastic lens, I found that in time though, the Plastic (initially Blue Reflector) then chromed over the plastic, had a tendancy to discolour, fade.
That usually is telling, as to where a torch is stored, and for how long.
I purchased nine (9) of these, in what I believe was in the 1990's.
Like the Maglite 6C, the 7C is slightly longer.
I understand that getting the 7C Globes may be a problem.
As I remember, there was a Globe named Krypton Star, where it's Blister Packed package, can with three or so, alluminium washers, so that one may adjust where the filament situated, and for "spill."
The Krypton Star Globes, had at it's (the Globe) end, a magnified, or thickish, glass end, that appeared to "Throw" the beam further, than the standard 2 Globes (that were supplied in the Maglite Torches.
One Globe came as fitted, and the other in the Tail Cap, in a foam protector, that was made to fit nicely, in the Tail Cap, just under the removeable Tail Cap spring.
As I recall, I paid approx $80 AU (Australian $$$'s) for mine.
I still have several, and are unused.
The "D" Size Maglites, Streamlights, are just a bit too big, in the hand, whereas, the C Cell Torches, are much easier to hold, and, these can be used as a Self Defense, defensive weapon.
The best was to hold these Torches is in the strong hand, high, about your shoulder height, with your forefinger on the beam Activation Button, and using it tactically, by just pressing button down, until "ON."
Use the shadow of darkness in your favour, being careful not to lose your night vision.
An excellent and practical design is the Maglite, so much so, that they, Maglite, have introduced, an LED (Light Emitting Diode) Replacement Globe.
I doubt though, that they will be anything near the brightness of the newer LED disign Technology by CREE.
CREE, are looking to be among the brightest.
But nowhere near as bright as the HID (High Intensity Discharge) that are available from Bright Star.
Hope this snippit, furthers your interest with Maglites and more.
