Get some T-5's...or if your looking at long term, look at LED 4' tubes. There is also pretty nice high bay induction bulbs out there. All bulbs have made some super advancements in the last year. DO NOT buy sight unseen....bulbs come in different kelvin, and the wrong color can be as annoying as too little light.
LED is obviously more money, but from a business perspective, the least amount of time you spend on a lift or ladder, reduces your exposure to liability (i.e. employee gets hurt in a fall) Lots of start ups infiltrating the market, so buyer beware, and make sure you get a good lighting company (Cooper, RAB, etc.) Companies that have been around will continue to be around.
Check with your local power provider to see what incentives they may be offering to outfit your new shop. There's tons of incentives, so don't give up if someone says no.
Your question is kind of broad, but if you're overwhelmed, pm me and I'll get my phone number and try to get you some contacts out in your area they can get you direction.
