I would cut down on the photoperiod in first few day, and maybe put a screen over the tank top to cut down on the intensity. You don't want to bleach your coral due the sudden increase in light intensity.

Either that or just change one bulb at a time with a two week gap between. At least that way you wont have to waste any light by shading it out. But defenately do it slowly which ever way you decide to do it.
