Been using Quantum Lightning Rods myself. Most all T6, T8, T10, and T12 will fit the same mounts (medium bipin). The exception would be the waterproof ones that are matched to the tube size, the smaller tubes would then not be waterproof I suppose. If your light fixture has metal clamps that hold the bulbs instead of the endcaps being mounted, you may have an issue unless you can bend them smaller.
