Surely to many of us, it does not matter what different members are sporting in their nether regions. A shared interest can be a wonderful thing amongst sentient individuals.
Back in the 60's, the Ray-0-Vac whack was standard operating procedure for activating a flashlight. Internal alkaline crud all too often encrusted any hopes of enlightenment. Darkness held sway.
Latter 80's security work led to a B-Lite then Streamlight with the archaic NiCd cells.
At some point, in an REI outdoor store, the (currently woman owned in Blachly Oregon) Laughing Rabbit Incorporated Photon Micro-Light beckoned all to try turning it on while still in the package. That opened up a new world where a late afternoon wilderness walk might extend into the night. No problem. With the Photon and a good dog, who when told, "Let's go home" would guide the way back to familiar surrounds.
CC Crane sold me a cluster LED modified flashlight (and Sangeon radio).
A tragic encounter with a drought stricken starving predator impelled the purchase of a SureFire U2 because the alkaline C cells in the CC Crane flashlight were quite depleted during the event.
That MCE(?) emitter in a double 18650 Olight really opened up the field of view (until the switch wore out some years later).
A search for a way to increase luminosity of the U2 led to candlepowerforums.
"Let the spending begin..."
Thanks all members for the knowledge gained, and laughs spilled.
