The original garage blueprints included just a single light fixture for the garage. Even though my vision for the garage wasn't elaborate at that point, I knew one incandescent bulb wasn't going to cut it. We installed four 2-lamp T8 flush mount fluorescent fixtures in a 2 x 2 configuration. More than enough light for an ordinary suburban garage, but this place is far from ordinary... 
The predominantly black floor and grey walls have had an adverse affect on the amount of reflected light in the garage. I have always used supplemental light sources (LED lamps from Home Depot) when I am detailing, which I will continue to do, but I needed to upgrade the overall lighting situation. My brother-in-law is an electrical contractor and he presented me with a number of options. I considered swapping out my 2-lamp T8's for T5, T5 HO, T5 vapor sealed or LED's, but I decided to keep and add more of the existing fixtures. With the 32 watt "cool white" Sylvania bulbs, they actually throw a clinical tone of light which reminds me of LED's.  
Planning the lighting layout was tricky. I ended up adding five new fixtures, four of which run perpendicular to the existing four. The garage rail mounting brackets were the biggest obstacle. I wanted to install the side bank of lights further out towards the walls, but the garage punch-out brackets were in the way. Although my original plan didn't work out, I am pleased with the layout because it is symmetrical, and more importantly, it has flooded previously dim areas of the garage with tons of light. I now have 18 bulbs instead of 8. The difference is substantial.  
​The fixtures are manufactured by Visioneering which is a brand of the Viscor Group out of Toronto. The units are 2-lamp models of the MNE "Magic Neutron" line of surface mounted fluorescent fixtures. The model number is MNE248-T832N120. Full spec sheet can be seen here. The bulbs are 32-watt "cool white" by Sylvania.
