My garage from a couple of years ago when first built. It shows 3 of 4 600mm x 600mm LED panels surface mounted. They are 40w panels from LED Hut. Its very good but wish I had 2 more on the lower roof section as well. You really cannot have too much light IMHO
White walls and ceilings make a huge difference too and then I spent £500 on decent plastic floor tiles on top of the power floated concrete floor which makes it very comfy to work on. The work bench is solid Beech kitchen worktop type and can support an engine or two
Things I would do differently if I did it again. More power sockets. I have 2 doubles on each wall but the washing machine, tumble dryer, fridge and freezer take up all the sockets on the work bench! Radio, vacuum cleaner, security camera, tool charger, trickle charger take up another 5 which leave 3 spare sockets all on one wall behind the car! The garage door needs to be insulated, for reasons I now can't remember the builder insisted this one would be fine...it is not
Several things the builders project manager questioned (like the power floated floor and painted walls and ceiling) are important and in the grand scheme of things cost bugger all more at the time but they kept trying to cut corners in the garage as it was 'just a garage'
As it is today!
