Out in the open air or with good air flow, that might be true. However, the bulbs are in a confined and more or less sealed space. As long as the bulbs are on, xx watts of power are being supplied to it. Pretty much all of that is converted to heat, and the surface of the bulb will just keep getting hotter and hotter until something fails. The only cooling is through the surfaces of the light enclosure (sides and lens).
