While High Intensity Discharge (HID) lights are more efficient (more lumens per watt), their higher initial cost, time delay (absent additional features), potential re strike issues, mounting, extra weight. etc. etc. makes the readily available, relatively cheap, good color rendition (subject to bulbs), easy bulb replacement strip fluorescent fixtures attractive for many shops.
Id go with Fluorescent but that"s not to say depending on the shop design and ceiling height and color and the fixtures used, HID might be a better choice over the long run. A lighting engineer would need all the physical info and your needs before making an informed professional choice.
Its been years n years since I attended General Electrics Lighting Institute at Nela Park, but do recall some basics. The general rule of thumb when computing how may lights/fixtures are required at a given location, is Foot Candles = Lumens X Coefficient of Utilization (CU) / Area. In an office environment with a white low ceiling and reflectors, a CU of 70% + may be attainable as I best recall (NO Warranty Billy Bob so dont have a calf) while a higher dark colored ceiling like in a shop with dark floor the CU would be muchhhhhhhh less.
Things such as a white reflective ceiling and good reflectors improves the CU and while you might (depends on your use and needs) get by with 50 or 60 Foot Candles or less in a shop 100 would be nice, but again the ceiling height and color and reflectors and fixtures used make the difference.
DISCLAIMER this is merely an opinion and like all others here it may be right and it may be wrong, I"m NOT saying if it is or it isn"t, take it or leave it, your choice.
