I used to install POS [Point of Sale, not peice of -you know what] systems. I also used to install video surveillance systems. So, ran alot of level 2 data wire. That was a few years ago way before stumbling upon CPF. Mostly used minimag, mm clones, and 2D incandescants. However, if I were still running cable now, probably use a headmounted LED light for close up work [like crimping or patching in crawlspaces].
My 2AA LED Legend would be for medium throw. [too many times my minimag batteries pooped out or bulb burned out in mid run.] Haven't modded my minimag, yet.
Then for throw, maybe something with an LSHD. [Don't have one, yet.] Or maybe one of my bright incandescants.
Of course, I would carry a backup. My EDC is a dorcy AAA. That can get me to where my other light sources are in a pinch.
If you do like your minimag, the dropin mods I hear about are great. Eliminates the bulb burnout and short runtime problem.
There are lots of great suggestions here in this forum. these are my 1 1/2 cents worth. [not a guru, yet.]
