Not sure which specific fixture would be best, but all T5 Bulbs require an Electronic Ballast (flicker free) vs the previous T8 Bulbs that work on Electronic Ballasts (Better) and Magnetic Ballasts (Worse [They Cause Flickering Upon Startup]). So any fixture that fits a T5 Bulb of your measurement will work (Assuming it has the right wattage) as all T5 Fixtures are Electronic Ballast. A T8 Fixture will not fit a T5 Bulb and a T5 Fixture will not fit a T8 Bulb. I hope this helps.
