not all t5 fixtures are easily retro-fitable (probably not a word)
I am assuming you have a linear bulb that fits in the t5 sockets (similar to what orphek tried but abandoned)
the problem was that you had to disconnect the ballasts and run a dedicated power supply which was no longer convenient.
at $1800 you could buy a brand new fixture. Possibly a couple depending on the model.
we need more info
