this is what reefers think....that t5 should be cheaper than mh....
since u are looking at 6-8 tubes, of couse its much expensive. If u are paying for the commercial units, it will be atleast @ 1k.
btw, i have not seen hilux having 250watts
if u are comparing to a china MH fixture, of course they are cheaper....but is it worth to buy? check out what they are using and u will noe why....
cheers
