Been meaning to recommend to all workshop builders that they incorporate a couple of those cheap battery backup lights (£9 each last time I looked) that come on automatically in the event of a power failure. Not that I'm expecting you to carry on working but more of safety.
If the power dies along with your mains lights then you will still have some nasty sharp spinny things winding down and ready to bite. Battery backup lights will allow you to retire gracefully !!
