| Re: T5's
humm, have you read throught he T5 Q&A thread on RC. many many many tests done on that thread. my own test show 80wT5's and 250w mh(watt for watt)where very close at 18" under the water line. i have clams and acro's under 3 80watt T5's doing great. dont forget the watts on the T5 bulbs. 39watt bulbs and 80watt bulbs are not the same light. if you compare a 250watt MH and 3x80watt T5 they both do great. now take the 250w MH and compare to 5x54w T5's, the T5's might not be as close. but if you take a 150w MH and compare to 2x80w T5's the T5's out do the MH. just something to consider. everyone keeps lumping the T5's as if the bulb wattage means nothing. example, the thinking that 6x39w bulbs is the same as or more than 4x54w bulbs, this is not so. the 4x54w bulbs will provide much more PAR at deeper depths than the 6x39w bulbs even though less watts are used. watt for watt T5's and MH is about the same. |
