I got the lights and put them in my Coralife 2x96 fixture 8 days ago. I didn't realize how old and faded my lights had become. The new lights were very bright and in fact, I run 1 for 9 hours and the other on a seperate times for 5 hours. Plants are perling much more than before and the Ludwigia Pantanal and Tonina Belem have doubled their growth rate. Unfortunately, my Cuba and Aromatica have also doubled and need a major trim. I may just run the 1 light for awhile and see what happens.
Thanks Chris. These were a bargain. I only wish my other 36" light used square pins instead of straigt pins.
If you still have them next meeting, I will definately get 2 more to use next year or to get a straight to square converter.
