goose neck, industrial quality, battery powered LED (bright) light

LED, clip mount, battery powered, flashlight.

a complex machines, aligning this and that. We all struggle with "light". There just isn't enough.

but they are hand held. We need a goose necked, battery operated light, that clips. The areas are tight, so it can't have a head a foot across (like a trouble light flood).

on it. It must clip mount. It must be bright. It must last at least 4 hours.

Is Black and Decker snake light close? You may need to work with a machine shop, have them drill and tap and mount on a clip for you, on existing light of some kind.

I bought a cheap one when I got frustrated working under a sink trying to hold a flashlight in my mouth.

Smartest thing I've done in a long time. It's amazing how often I grab that little head lamp. Mine is single LED, switchable from 35 or 100 luments, I never need the high power. Cost about $12, or you can pay $300+ for the good ones.

I have a Princeton headlamp (which I believe are the original that everyone clones!) made in USA. Excellent, but an older non-LED.

I like the batteries on back. Helps with balance, I'd guess. I've never had a strap on head lamp with batteries on the back.

This one from HF, you can put in a LED module for Mini Mag, and it works fine. The elastic goes limp after a while, so buy several, and move the module as needed.

I've got an older Black Diamond that uses 3 AA's in a battery box at the back of your head. It can be awkward. My go to headlamp in a Tikka with the AAA's contained in the lamp housing. It's lighter and handier.
