Power Usage of Neon Light in Light Switches
« on: July 22, 2024, 11:00:07 pm »
Does anyone have any specifications or real world data (i.e. using a kill-a-watt or similar) on how much power is being used by the neon lights that are in the wall light switches or a neon light in the small plug switches (see photos)?  Neon not LED.

the load is between 50 to 200 kilo ohms

so around 1mA

Often saw a 220K series resistor with 240V neons (haven't looked for decades) so if the neon was shorted it would use 0.26 watts, so just a very tiny bit less than that.

Neons run at about 60V IIRC, so (240V-60V)/220k = about 800µA or 200mW total power consumption.

Thanks for all the replies.  FYI -- I'm in the US.

So about 100mW.
