Much would depend on reflectors that may or may not be as effective as your's or mine ,and or how high above the surface of the tank light is sitting, and or how many hour's you/he are running all light's or part of them,siesta period, one four foot double tube fixture, or two 24 inch single bulb fixtures,etc, but I do agree as I mentioned,,that duration and or intensity might be reduced.(what could it hurt?)
Not like he can increase DIY CO2 ,which is hard to supply DIY at sometimes needed level's in larger tank's.
Most are subborn when it comes to lighting, and it is the light,that drives everything.
