Supposedly about 30% of the normal operating power. However they
include occupancy sensors, and so switch to standby (0.4W) when
they figure no one is about to look at them.

Which reminds me of someone (Big Clive?) who tested light sensitive LED
night lights and found running the sensor took more power than leaving
the LED on.

In other words the power consumption of the light saving night light
was greater than one which was on all the time.

(possibly apocryphal story but) IIRC there was s sky box like that -
where in "standby" it would turn on a LED to indicate that, but since it
needed to keep the rest of the box running (but with the video and audio
muted), so it could receive OTA updates etc, it actually used very
slightly more power in standby so as to light the LED.
