lighting question

[Brenden]

I currently have 4- 48" odyssea t5 fixtures with antic bulbs to suppliment my MH and to have a "dusk" effect. One bulb on all four of these lights do not work after only a month of use. Any ideas? I am thinking of getting something like this. http://www.marinedepot.com/md_viewIt...product=PF5117
I was planning to run 2 single bulbs end to end down both sides of my MH lights. (total of 4) Anyone see a problem with this or know what I could do on my current lights?

If you swap bulb positions, does that position cause bulbs to go bad faster?

You might have a wiring or end cap problem.

I personally am partial to Ice Cap ballasts. They have really good technical support if you run into a problem like this.
