It is challenging attempting to take photos of lights.  I am in awe of how bright my garage has become now that I have added some additional fluorescent fixtures.  I took 50 photos, using every setting I have on my camera, but I could only capture two photos that accurately depict what the light looks like in the garage.  

With the increase in light output in the space, I can now see parts of the garage that I never really noticed before.  For instance, I can now see that the shelf on my tire rack was filthy.  I'm going to have to be more diligent with my dusting!  

I have found the answer to my lighting issue.  I am going to upgrade the 4 existing 2-lamp T8 fixtures with 4-lamp models.  I'm in the process of working out the install date, but I'm excited at the prospect of doubling the amount of fluorescent light in there.

My garage isn't dark by any means, but I need it brighter.  I have 4 2-lamp 48" T8 fixtures, but I am playing with the idea of replacing them with 4-lamp models.  I am having some difficulty finding exactly what I have in mind, since most 4-lamp fixtures are designed for high bays.  Part of me thinks mounting fixtures designed for commercial warehouses would be awesome, but the practical side of me realizes that would be overkill.  

Here's what I'm currently dealing with.  It's adequate, but I think a world-class garage deserves world-class lighting.  Once I have the fixtures, it's just a matter of having my brother-in-law's electrical firm mount them up.
