....then the hot water system later in the night....I suppose the washing machine will do this too..
Should be lower wattage bulbs, not low voltage lighting. Try and stay away from most of those transformers. They're noisy. That link you provided to Ethan's site, the transformer he has there would be ok to use as a "dimmer".Low voltage lighting it is then.
Every switchboard I worked in had transformers - and from memory I never found a really quiet one - every one hummed - that is their nature. So I will now research low wattage bulbs for our mains 240v - thanks.

Reducing the voltage applied to a light bulb will reduce the filament temperature, resulting in a dramatic increase in life expectancy.
One device sold to do this is an ordinary silicon diode built into a cap that is made to stick to the base of a light bulb. A diode lets current through in only one direction, causing the bulb to get power only 50 percent of the time if it is operated on AC. This effectively reduces the applied voltage by about 30 percent. (Reducing the voltage to its original value times the square root of .5 results in the same power consumption as applying full voltage half the time.) The life expectancy is increased very dramatically. However, the power consumption is reduced by about 40 percent (not 50 since the cooler filament has less resistance) and light output is reduced by reduced by about 70 percent (cooler filaments are less efficient at radiating visible light).
