A few years back, I was at a store that was being re-modeled. They were ripping out all the commercial two circuit track lighting. I asked what they were doing with it, and was told it was going to the dumpster. They gave me all the track and hundreds of fixtures and bulbs. I sold or gave away most of it, and stored the rest away. In my new shop I will have track lighting over all the benches. I will have drop down leads where the light needs to be close, and overhead spots or floods where more appropriate. With track lights, you can place whatever size lamp you want, wherever you need it.
While the general lighting is fluorescent, I have track lighting installed in my jewelry work shops, as well. The other neat thing I use in my jewelry shop is a dentists articulated lamp. I can move it close or far, and position the beam as needed. It moves up and down an eight foot long track. I got this for free , along with all the cabinets and a ton of equipment when ripping out a dentists office for a friend. It may end up being moved to the new shop over the grinders.
