Simon,
As a EE you're argument seems reasonable to me, but I never claimed that
the bulbs were rated at the same wattage and it's the bulb's
manufacturer, not me, that claims they get hotter. Then there is the
empirical evidence: they DO get hotter.
Didn't we have this same discussion on the list a few months back?
