i know this has been discussed a lot and i've read a fair number of posts but i'll ask anyway.
I'm looking for 8' T5 fixtures but can't really seem to find any ... at least at the big box stores. I have not gone to an electrical supply house yet. I'm thinking the 8' fixtures would be preferrable since the T12 fixtures and bulbs seem to be well less the twice the price of the 4' onces.
So...when you bought fixtures what did you choose and did you find a source for reasonably priced fixtures -- mail order, big box, ...?
