Nice work...thumbs up on the excessive lighting. Not enough light in a workshop is a pet peeve of mine

If those shop lights have replaceable ballasts you can change out the ballasts for digital T8 ballasts and put T8 bulbs in and get about 40% more light output on the same power use, and no cold weather issues like T12 ballasts have too. If they are T8 already disregard my last sentence :)
