I have a Coralife 2x96w CF light fixture on a 58 gallon tank. If use both lamps I find it is too bright so I normally use one lamp only (i.e., 96w). By using one lamp, the other no-using lamp blocks the light to reflector and it has less useful light than one lamp only fixture. I feel the light is a little lower than what I wish. If I could replace one 96w lamp with a 40w (I know it is shorter), then it would be perfect. I just don't know whether it is safe to do it or the 40w lamp will be burned out quickly.
One thing I forgot to do it is, remove the no-using lamp and then it won't block any light to reflector and it won't be 'burned' by the other using lamp. I was stupid not to do it earlier.
