It's probably because PAR meters don't perform as well in the wavelengths of light that are commonly thrown over marine tanks - the closer to the blue end of the spectrum you get, the poorer the PAR meters tend to perform. That probably accounts for some of the differences seen despite what the PAR meter says.
Kien, nice review on the LED light. So where is this unit going to go on your system now? I can't imagine you'll be replacing your central halide for it. Maybe an expensive refugium light?
