Like the title says I am saling 2 Marineland 48" 216w 4 bulb t-5 fixtures. The fixtures are just over a year old bought in april 2009 I bought the 12k lights in july 2009 so due for a changing. the actincs came with the fixture so they will need changed also. They are single reflector for all the bulbs.
The switch for the light is a 3 postion sw. press once for actinic or 12k (depends are were you place the bulbs) press again for the oppsite, press a third time for BOTH to be on, press again turns all off.
