Problem is, if the light is off and there's nothing on the display - the display is actually on (filament heater is running, 60v PSU is running). Ok, so no big deal, but it does increase the power consumption/heat, which is not terribly environmentally friendly if you're leaving it like this overnight on a regular basis.

We're not talking *majorly* (ie, it's probably under 2W) but it's the principle :)

I'll try to get round to the standby LED state stuff next week.
