Lamp voltage and power

Release Time:2018-11-21 14:33:10  Views:

Lamp voltage and power can be seen on the nameplate of the lamp.

For example, the nameplate of the lamp reads “220V, 40W”, which means:

The voltage of the lamp during normal operation, that is, the rated voltage is 220V, and the rated power of the lamp is 40W.

If the lamp is operated at a voltage less than 220V, the actual power will be less than 40W, and the lamp will be darker;

If the lamp is operated at a voltage greater than 220V, the actual power will be greater than 40W and the lamp will be brighter. Of course, if the voltage is too high, the tube will burn out.
