I've done two things to help with light in my shop:
1. Clean the top surface of any exposed fluorescent bulbs. I noticed when changing a bulb that they were covered in dust on the top. It was like I doubled the number of fixtures.
2. My shop is an attached garage with a door opener that has two 60 watt incandescent bulbs under it. The bulbs can be operated separately from the door opener and they are directly above my tablesaw. I removed the 60 watt bulbs, installed a "Y"socket in each receptacle and installed 2, 100 watt CFLs into each "Y". This increased light output from 120 to 400 watts equivalent and only demands 92 watts total so there is no concern about overloading.
