I don't want or care for dimable lights.
In the real world most lights aren't dimmed.

Plus these T5 fixtures are being used outside and in unheated buildings.

Moreover there are dimable T5 high output motion detection fixtures, where I work we have a few warehouses lit with these. They pop on at full power, dim down to stand T5 brightness, then turn off if they don't sense any motion after a few minutes.

If I want to "dim" my T5 fixtures I take the light fixtures that came with dead ballasts and rewire them with 2 ballasts.
So far I have only installed twin high output ballasts in my 4 tube fixtures and wired them to 2 switches. I could install a standard 2 tube ballast for 28 watt tubes and a high output 54w ballast in the same fixture if I wanted to.
2 high output ballasts give me 10,000 or 20,000 lumen settings, a standard and HO ballast would give me 6,000 , 10,000 or 16,000 lumen settings.
Plus the standard ballasts are cheaper than the high output ballasts, making it even more economical.

Edit: now that I think of it the HO plus standard ballast in the same fixture is a pretty good idea.
