Hmm, fluorescents loose brightness with time. You might find that four new CLEAN tubes will give a big increase in the light.
LEDs are either not that bright or short-lived if bright, and you’ll need a lot of them to cover that area. Even the good ones lose brightness with time (witness my kitchen after ten years and conservatory after four), my house is all LED, except in the garage where we have four six foot 60W fluorescents! The garage uses more watts in light power than the whole of the rest of the house with all lights on.
Fluorescents are good if you have the electronic ballasts, they last much, much longer. On mine I replaced the starters and chokes with electronic, best lighting investment ever (quite cheap a few years ago with a trade card at the local electrical wholesalers).
Gardens looking nice Geoff  well worth the effort! Can’t advise on the lighting, when my electric garage door is open, it slides into the ceiling pace and blocks one of the two twin tube fitments  I also drive into the garage and bonnet up, that blocks most of the light from the other fitment!Â

i wondered why you always wear a cap lamp barrie  .Â
Usual crap with a garage and most of what I say you cannot do much with for many reasons.
You need another shed to store all the usual crap in to allow you to work on your car, you are bumping into stuff to walk round the car.
It is a biggish single garage but as always width is an issue even with all that stuff in another shed which it is not.
The lights need to be below the roof trusses.
You need to get all that roofwork painted white to reflect the light down and a thin false ceiling painted white will help.
Assuming you have cleared the crap out to another shed, painted the cieling etc., and maybe do the floor white or gray you have three times the basic light needed for a parking garage.
Depending on what you are doing you need around 2.5 to 3 times the light you have to make it good to work in as a workshop.
Due to the width of the garage you may need say two tubes at each side edge of the garage. One right behind the door and another one above the bench if you can move stuff.
I would be tempted to get some small strip lights or bulkhead lights down near the wheels.
Fluorecent lights or similar with LEDs have a similar light output per mtr, unless you are in there every day through the winter you will not cover the cost of LED’s over fluorecent.##
Have fun but it will be difficult to get it the way you want.
You think your garage is too small, you wanna try mine, you can drive into the shape of an MX5 with all the junk i keep.
I need to do a sideways shuffle without being able to turn around to get in or out of my car.
