T5s don't need to be chanegd that frequent, at 60% of T5HOs life cycle they out out over 90% of their original output and sayign a T5HO lasts rought 30000 hours 60% is 18000 hours at 10-12 hours a day is roughly 1200 days thats 5 years. MH
is where the lights dimand at 40% life they are down to 70% their original output and they last about 15000 hours.
i hadn't changed my lamps in a year and ahalf on my 4 lamp fixture and noticed minimal change in spectrum color or intensity and the corals were un effected.
i'm not sayign go 3 years without lamp changes but to say 8 months, you're just pissing money away.
in the long run LEDs will save you money i just picked up a 48 LED
kit from rapid LED
that will easily light up a 75g and at peak those will run half the wattage of the T5HOs and possibly put out the same intensity. granted they did cost me $500 for dimmable but the tank will run cooler and they will allow me more functionality
