WebFor example, mercury vapor bulbs ranging from 175-400 watts are primarily compatible with metal halide ballasts of the same wattage. So, do not forget to check this compatibility. ... If you are done turning the switch on and off numerous times, leave it off for some time. Then turn it on for the final time. After that, rest the light completely. Web18 nov. 2024 · A heat anticipator is a metal resistor that heats up when electricity passes through it, much like the burner coils on an electric stove or a heating element in a toaster. The anticipator receives electrical current from one of the low-voltage thermostat wires; the amount is very small, typically between 0.3 and 0.4 amp (ampere). エクセル abcde オートフィル
