A: There would be no issue with using a KinoFlo 4bank (either the 2' version which weighs 7.5 lbs or the 4' version which weighs 11.5 lbs) with the Kupole. I contacted Kupo regarding your inquiry. According to Kupo, if you are using a single Kupole mounted between a rigid floor & ceiling, and with the rubber pad attached on the rubber cover, if the light fixture is extended up to 0.5 meters (19.68 inches) from the Kupole, it should support up to approximately 24 kg (52.91 lbs). If the fixture is extended 1 meter (39.37 inches) from the Kupole, it will support approximately 12 kg (26.45 lbs). If you are using a single Kupole braced horizontally (wall to wall) with rigid walls, it will support up to 15 kg (33 lbs). If you are using a three-Kupole setup, two poles positioned vertically and one horizontally functioning as a crossbar, the crossbar will support up to 20 kg (44 lbs).
