What I was going to do if I were to go the t5 route was to gut my current strip and install the t5 ballast. This is what I would have to to pay for a t5 setup here in Canada
Ballast $60.00
Lights $30.00 each
Cover if I did not use my current one $120.00
Reflectors $65.00
Now is you can get your whole setup for $120.00 jump on it, that cost is just for a new cover in our good old country of Canada.
Check the replacement bulbs for the PC, sometimes these can be steep in price, here they are that is for sure.
This is why I am going to sit and think a while for my situation. Things are just so expensive here, everything has to be shipped in and by the time I pay the shipping cost I might as well have just bought it here.
Good luck and let us know what you do.....
