m/h or led?

Providing the wattage and electricity usage won't be too overwhelming to your electricity bill, go with the MH unit.

Otherwise, find something else. I wouldn't use low quality LEDs on my tank. I don't think you should use them on yours, either.

Low quality LED = pain

T5HO or MH or maybe a good LED fixture (expensive!!!)

this light will be a upgrade from an odyssa`6 foot thats starting to die .is there any notacable difference in make of light ?i saw a gessmen for sale for little more then the hamilton fixure ?

Provided the Giesemann isn't too old, it is better quality than the Hamilton. Better reflectors. Since you didn't answer my questions and didn't provide power specs for the fixtures, I can't help you out much more.
