If this is going to become a new workshop for you, you should consider track lighting from Juno. http://www.junolightinggroup.com/sys...ls.aspx?id=163
. If there was only a lamp in the ceiling, your bedroom will be Single Circuit design . If you had a fan and lamp combo, you likely have a Two Circuit design. I don't know if you could take advantage of the Two Circuit track systems but it is an option.
You can install the track in many configurations that radiate out from, or overlap the junction box in the ceiling. Maybe you want an X pattern pointing to the corners, or a square that is inset from the walls by a couple feet.
With track lighting you can put up and adjust the placement, and quantity, of spot and pendant lights, to suit the need of each project.
