I have a toilet at the end of a dark L shaped hallway and have put a dimmed LED lamp in the room.

 

The lamp is a 230v 5w dimmable bulb... (No brand name from Aliexpress)

 

I have put 100nF X2 capacitor is series with the bulb.

 

What power with the lamp draw in this dimmed mode?

 

I guess I could do a calculation on the assumption that the bulb is a 5W resistor equivalent.

 

Do household energy meters record resistive or reactive loads?

Household power meters are just measuring real power, so the apparant power is meaningless.

 

If capacitors dimmed the lamp then it is probably already just a capacitive dropper inside it, so it would already be an almost totally capacitive load. considering it a 5w resistive load would be way off the mark.

 

In anycase, it will be so low as to not be worth worrying about.
