Non-Cooled T5 tubes lifespan

[vikz]

Hi guys

Was wondering, how long would a pair of T5 tubes last if just using a simple T5 Ballast and reflector setup. I.e Not a pendant with fan e.g. ATI Sunpower etc.

Would use most likely ATI or Pacific Sun Tubes, Any ideas of how often they would need to be changed?

ATI tubes will keep a good spectrum level for 6-7 months to satisfy SPS acropora dominant systems. You can go a month or so longer if your tank isn't SPS

I replace my tubes on my retro kit every 10-11 months.
