Lamps would perform differently when controlling multiple lamps at the same time. The situation is even more obvious under low brightness.
The difference has much to do with the output tolerance of the driver and the Vf tolerance of the LED light source. Our technology is capable of keeping the output current tolerance below 0.5%. By coordinating with the adjustable VR on the driver to manually keep all brightness synchronously, the slightly different brightness brought from the Vf tolerance can be fully eliminated, elevating the lighting experience.
