Where to mount actinic with halide?

[Canadian Man]

So with my new hood I am making for my 90g tank my 2 x 250 w Iwasaki's will be mounted about 8 to 10" off the water surface with an optimal (Perpindicular ) reflectors.

so I want to mount 4 t8 actinic bulbs in the hood and I origionally wanted 1" off the water surface with 2 mounted at the extreme front and 2 at the rear .

What does everyone think?
Should I mount them higher?
If I do I couldnt see much benefit except that it may block less light cause there are closer to the light source and not blocking as much light spread.
