if you run flouros would they last longer running 24/0 rather than 18/6 16/8 etc. because with 24/0 they only have to fire up 1 time instead of 365 times a year. in my experience lights burn out right when you turn them on instead of just dying out while burning. i had 8 4ft agrosunn t12s running 24/0 in my veg chamber for 18months and they were still fine when i had to shut down my grow for security reasons(1 year probation, only 8 months to go, i can't wait!!!). i wonder if they would have lasted that long if they had to fire up over 500times instead of just once??? i could be totally off base with this whole thing but i am curious.
