Yes, the 4 light system is 60in.

I also got 5 of these lamps already (pics below). They are 48in. I am only able to add one because of the other light taking all the space in my hood. So I can not add two, but I did add it already to check it out. The worst I will have to do is just buy new bulbs for the light. I bought the 5 lamps from a pet store upgrading their lights. I got them for 5 bucks each. I never used them in my tank because I felt they did not provide enough light and they all wouldn't fit into my tank, plus it would have made a huge mess of wires. LOL
So as of right now, I got 6 lamps shining in my tank. 4 are 60in lamp and 2 are 48in lamps.
The ones in my 4 lamp fixture are only 2 weeks old and the ones in the 2 lamp fixture, I have no clue how old they are. :-p So I will need to replace them before I put the anemone in. I am also thinking of getting new whites for my 4 lamp fixture that are not Odyssea. I am just praying my Odyssea has no issues like so many say they have with them. :-p
I said I was going to buy two new 30in ones to span my whole tank before I realized I already had dual T5 lighting fixtures. I forgot about them. LOL
