Hello all. Good topic, being we spend so much time working on our cars.
The more lights, the better. But...choose your lights.
I have a two car garage.
First, paint the ceiling white to reflect the lights. Use a light color for the walls. Most use white, but I choose to use light blue, for all white looked likes everyone else's garage and reminded me of a doctors office.
Finish the floor, with an epoxy paint. That will help reflect light back up.
I first used 3 halogen lights that looked like the long fluorescent style. Bright you bet! Hot, you bet. I would start sweating after a while. Not good.
I removed them and installed 5 fluorescent fixtures. The key is to use the good ones for the cheap ones hum.
Most important, use the brightest fluorescent bulbs. Yes, they cost a lot more, but you will see the difference. Looks more light natural light.
Placement makes a difference. Spread them out and keep them all at the same level. I hung mine a little lower than the garage door. So that when the door is open, the door does not hide them.
Here's a photo of how bright my efforts have worked.
Oh, only one Healey is mine. Other one is a friends we are working on. How honest am I /ubbthreads/images/graemlins/smile.gif
Photo is with the gargage door closed and the 5 lights on.
Cheers, Roger
