Need options for ceiling fixtures

[Scooter70]

When I ran wiring for lights, I went for "overkill". Now that I'm putting up fixtures I'm rethinking things. As drawn, I have 13 4' T8 fixtures in my 2-car garage. Is that too much light? (Is there such a thing?) The horizontal fixtures are already up. They're on the main switch and are used for general lighting. My original plan was to have more lights on the sides of the cars for when I'm working on tires/brakes/etc.

My question is: If 8 more T8s is overkill, what other options are out there for lighting fixtures to provide light on the sides of the cars? I already have the wires run to these positions, so I'm looking for fixtures alternative to 4' long T8s. Or... are 13 twin 6500K bulb T8s "just right" for 550sqft of garage?

Just my opinion but that last picture is showing a pretty bright garage already and you haven't painted the walls yet! Then again you haven't hung stuff on those walls yet either. Per your plan I would keep the fixture above your planned workbench. Maybe even doubling it up in line with your other horizontal lights. For side lighting I might try mounting two fixtures on the left and right sides keeping the center lights in those two banks out for now. You can always add them later. Ideally, mounting them on the wall would give you what you want but you already have the wires pulled in the ceiling. Hopefully the lights are switched into separate banks. If not you're going to need welding glasses and sunscreen when you throw the switch.

Personally I would throw cans in those existing wire spots provided you have access.

Need actual interior dimensions with ceiling height. Space between cars and walls will be in shadow without additional lights.

The existing lights and the ones in question are on separate switches. The secondary ones would only be needed when working on the cars (of when I need a tan).

That's an idea I hadn't thought of. Thanks. The attic is open and accessible so that's an option.

Garage is 22'x23'x9'. That shadowy area is why I planned for these lights in question.

I'd have the vertical fixtures in your pic run on 3 separate circuits so that each vertical column can be switched independently. This would allow you to use the horizontal lights for day to day stuff, and the vertical lights as needed for specific tasks. In the interest of additional flexibility, putting them on dimmers might also be an option.

It just hit me - You're not using LED. These are F32T8 fluorescent, correct?
Do you have ballast and lamp info? (mfr model numbers)

 

[Scooter70]

Sylvania 32W T8 bulbs (spec sheet) and Metalux fixtures (spec sheet).

TBH, I thought these had better CRI so that's why I went with these instead of LEDs. I guess I should have looked at the box.

PS-that Metalux will have a 120 only type B ballast, most likely from Sylvania.

Thanks CD. Unfortunately Sylvania has wiped residential ballast literature from their website. Scooter70, please snap a pic of the ballast in the fixture. Trying to get the BF (ballast factor) number.
