The other advantage is that the bulbs will probably last longer, because the most stress is put onto a bulb at initial switch-on, and having a dimmer in the circuit in most cases does not zap 240V straight across the bulb. instantaneously - even if the dimmer spindle is turned high. The voltage rises quickly but not instantly.
