your workshop is the very same size as mine and its not nearly big enough!!
one of the most useful things in the shop is as much as possible I use castors, on 3no benches, 7x12 band saw, 1m guillotine,
sheet metal off-cut trolly.
I park a 10'x5' trailer out back, so I need to move saw, guillotine, benches to do this.
but this means I can use otherwise dead space.
Another use for mobile benches is, i can configure them to be parallel to the walls or perpendicular to them.
each bench 2'x4' can be used individually or together to support an 8'x4' sheet.
The one other great thing about having as much equipment mobile is that you can CLEAN the the floor under and around them!
As for lighting I fitted 2no rows of 4each 5' twin Florissant's, but they are for a small amount extra electronic Ballast starters.(probably will fit another 2no in the centre)
I have to say I have had them up over 3 years now and are as good as new, but NO flickering when they start up.
and if you can get them in a weather proof casing, they stay clean. from dust and bugs.
