I am using something called "T5 LED conversion bulbs" in my T5 HO fluorescent ballasts. It's an LED bulb specifically made to work in the "old" fluorescent ballasts as people moved to LEDs. Maybe that's what OP is using? Mine work perfectly.

Btw, as to the original question. Mine are Sunblasters, but I just got them, so am not in a position to recommend them yet.
