This study presents an operating light system with spring balancers that perform gravity compensation at arbitrary positions in the workspace. The spring balancers, which are made of nominal compression springs with zero-free-length (ZFL) characteristics, are designed by determining the spring constant, spring attachment points, and the ZFL parameters. A test rig is developed to validate the performance of the balancers, and the unbalanced forces are measured by changing the vertical position of the astral lamp. Results show that the developed spring balancers effectively ensure gravity compensation, independent of the lamp position. Equilibrium errors are observed to be approximately 7-8 %, which are caused by some additional weight due to auxiliary linkages and the springs.
