Step-by-step. Turn off power to the fixture. Open fixture and remove the bulb and ballast casing. Using the wire cutters, cut both power (brown) and neutral (blue) wires coming into the fixture. Cap the wires with wire nuts. Use the wire cutters to cut the wires connected to the sockets. Remove the magnetic ballast.

NF F07

The impact of the ballast can cause damage to the affected area and in some special cases can cause a serious incident. The next mentioned inconvenience is noise from the air and impacts. Due to these points, many manufacturers equip their products with additional protective covers fixed on the subframe to isolate them from external factors.
