If you disconnect all the fluorescent lights from a ballast, but the
ballast still gets power, does it harm the ballast?

it dies from heat or the insulation breaks down from the high voltage.
Costs you either way- turn off the power.

Not for a while. It sits there, acting as a 12-or-so-watt heater untilIf you disconnect all the fluorescent lights from a ballast, but the

High Frequency electronic ballast designed for use with linear fluorescent
tubes.
Ideal for upgrading existing installation by simply taking a direct mains
feed into the ballast and changing the wall switch to a momentary action for
on/off dimming control.
a.. SwitchDim operation
b.. Dimming range from 10-100%
c.. Lamp start at 10%
d.. Defined lamp warm start within 1,5 seconds with a.c and 0ˇ6 seconds
with d.c.
e.. Switch via the mains or with digital control signal
f.. Integrated SMART interface
g.. Constant light output independent of fluctuating supply voltage
h.. DC operation in emergency lighting installations
i.. Safe shutdown of defective lamps
j.. Automatic restart after lamp replacement
technical specification
Supply voltage 220-240V a.c (200-280V d.c)
Power factor 0ˇ95
Operating temp range -15°C to + 60°C
Operating frequency 40KHz to 100KHz

It depends on whether you're in US or UK. Here a tubelses fitting is
practically an open circuit, the ballast will eat nothing and last
forever ilke that. Our fittings use choke and glowstarter, not an
autotransformer like the mericans use.
