well the ones I mentioned above I have (2 of themover my 55) decent light output. I like the fact they have seperate power cords. I can put my actinics and daylight bulbs on seperate timers. They have a removable plexi sheet to change the bulbs (clean the sheet) I think for the money spent, very good lighting. Actually... I did a review of them in our product revies section if you wanna read that.
