1000sq ft garage with high ceiling and realistically 600sq ft or so of work area
I'm loaded up on 4ft t8 fixtures on the ceiling (cheap ones at HD or lowes since they buy in such bulk). 11 in total = 22 bulbs
I have 4 CFL bulbs on clamp lights providing a 45 deg angle off the walls
Everything is in the daylight spectrum (5000k-5500k temp) that is important
all of the above is for 'general' detail work. not paint correction. I could actually use more horizontal fluro lights
for paint correction I have 4 par38 LED bulbs (single diode) mounted around the garage on clip lights. Again, in the daylight spectrum. I have a 5th LED bulb on a stand I can adjust. Kill all the fluro bulbs and the LEDs will show every swirl. Great for an initial walk around inspection as well as for use during the correction. I turn all other lights off except for the LED flood lights and my LED headlamp
Most people use halogen lights for paint inspection / correction. You can debate which shows more, halogen or LED but no question that halogen gives off a ton of heat plus LED is more efficient. 5 of my LED bulbs = 90 watts. My halogen stand is 1000w
search around the forum here. all of my lighting ideas were taken from stuff I saw on Autopia.
