Fitted new lighting to my new workshop a couple of years ago. I started with Electrical Factor, as Ian said, they sent a rep from lighting company. He provided a sample unit of each type.
We ended up with half each. Higher area at 5.5m has Halide, lower at 4m floro's.

The halides have a start up time with poor output gradually increasing for about 10 mins, then very good. If power is interupted will not restart for some minutes so must have altermnative or you will be in the dark one day!

Floro's are instant. Light also very good, wider spread due to bulb spacing.

Not sure about your tech description but halides had latest bulb available, floro's each have four U shaped tubes. Think they cost about 50 each average(halides less, floros more).
No problems yet.

Also important is position. Close to but not in front of rooflights, between vehicles not above.
