Sounds like you're describing a maglite

Maglites are perfectly fine flashlights for most people, maybe a little heavy but sometimes that's kind of the point (a lot of cops and security guards and such took to carrying them when their agencies started prohibiting nightsticks and batons, especially the bigger 4 or 6 cell models) for a long time they were basically the default flashlight, you had maglites, you had the big spotlight looking things that took a 6v battery, you had cheap plastic flashlights, and you had various small penlights and such (which were often mini maglites) and that was like 90% of what you'd ever encounter.

There's a good chance if you go rooting around in your dad or grandfather's car trunk, garage, basement, workshop, toolbox, etc. you'll find a maglite or 3 kicking around somewhere. I know I keep one in my car for emergencies and I'll probably inherit a half dozen more from my parents someday.

They still make them, pretty sure they switched over to LEDs (one of their selling points used to be they had a spare bulb stored in the tail cap) and I'm sure they're still perfectly reliable and rugged, you can probably still find them at most of the places you'd think to go buy a flashlight, and a standard 2 D cell maglite still costs in the neighborhood of $20-$30.

But there are a bunch of flashlight nerds out there these days, who want really specific form factors, battery types, features, led color temperatures, etc. and they'd probably pooh-pooh the humble maglite.

I get it to an extent, I have flashlights I like better, but I'm not about to nerd out about them, and if you someone sent me out with instructions to buy them a flashlight with no other requirements listed, I'd probably buy a maglite and feel pretty confident that it's going to be an acceptable flashlight.
