High pressure sodium lighting for shop....?

I need advice/guidance on buying what I THINK I want for my shop. The shop is 30'x50' with ample windows and 10'x12' rollup doors for ample daytime lighting. For night ops, I envision three large bare bulbs hung from wire rope (12/2 wire wrapped down the wire rope) one each from the three center ceiling trusses. I have found what I THINK I want on 1000bulbs.com: https://www.1000bulbs.com/product/4975/LU0100-0002.html

These are medium base bulbs with the right lumen rating and bulb shape that I like.

Question: what kind of base to buy? Do these require a ballast or are the bases just wired into the 12/2 wire, screw in the bulb and done?

Just looking for that vintage shape in a bare bulb; any recommendations much appreciated.

High pressure sodium and metal arc lamps both require a ballast to operate.

How important is color rendition to you? Sodium is a very yellow light.

Not only do they require a ballast..... they need to be operated in an enclosed environment like a fixture with a glass lens.

Long, long ago I worked in a shop that used HPS lighting. While it was bright and energy efficient the color was annoying. You can accustomed to it but it's odd and it's almost always used outside as street lamps. Mercury vapor or metal halide offer better more white color.

I'd like prefer no color distortion in the light; I'd heard that.
I guess what I'm understanding is that if I want a bare bulb hanging on a cord, I'll have to go with LED or incandescent (dying proposition). ??

I think your shop is too big for a few LED bulbs hanging in the center. You might have to break down and buy proper fixtures.

I have a couple 300 watt equivalent bulbs in the basement and they do a pretty good job illuminating that space. Not sure how many it would take for the size you have, though, but it seems like three would not even be close.

I would splurge on some high bay T5 fixtures.
F-Bay HBL Series

You could probably get away with 4 to 6 fixtures. And if you toss some high output 4100K T5 tubes in there, you're going to be swimming in crisp white light.

I have 8' SHO fluorescent lighting in my toy car garage. I used more standard twin bulb fixtures to spread the light source out more to cut down on shadows. The fixture you linked looks like it's more intended as a plant grow light as six bulbs in one fixture is pretty concentrated.

We use those types of lights at work all the time for warehouse lighting, 20 - 30' in the air. I can tell you from experience using them that the spread light very well and so long as a few are provided they do not create shadowing, nor do they create bright spots in the warehouses.
