Gday, This is a very simple question and it should only take one sentence to answer. It's not worthy of these forums, lol, but despite my efforts I cannot find an answer through google. If a light fitting says '40 watt max' and I stick a 60 watt bulb in it, will that have any adverse effects? I assume what will happen is that only 40 watts of power will be fed into the bulb thus not fulfilling the bulbs potential brightness, but I'm unsure and thought I better ask before I do it. Thanks in advance.
