Unless inrush current matters (as it can on many PSUs with
overcurrent protection). At the moment you switch the PSU on, that
lamp will draw considerably more current until it reaches operating
temperature. My point was that by using a higher-voltage lamp, the
difference between "cold" and "operating" resistances is much less.
