Replace a flourescent bulb every 6 weeks?!--I replace every 6-9 months and never had a problem with built in ballasts on T5 or VHO
If you go LED
, go with atleast 3 watt per LED
--Marineland is 1 watt per LED
. There is a big difference between what you can get away with and what will give you the freedom to house various corals. You can not house clams, SPS
, or moderate to high light corals under Marineland LED
's for an extended length of time and expect good results. T5's and MH
will allow you to do what you want.
