I did some measurements with my installed Doc Wattson. Measuring current flowing from my aux battery.

first, van as is:

leds off, 1W, 85mA
leds full on, 9W, 750mA
leds dimmed lowest setting, 1.7W, 140mA

Radio face plate off:
led lights off, <0.1W, <10mA

For interesting comparison, kitchen water level/battery meter panel on, led lights off, between 0.2 and 0.3W, between 20 and 30mA.

So the led dimmer control draws a little power even when off, but it is less than the the kitchen indicator panel.

Led strips both sides only draw 140mA power at lowest brightness. And that low setting is pretty good for a standby/casual use light.
