My two T5 tubes have been in for 6 months, say roughly 1400 hours use.
At the moment all seems fine in the tank.
When are they considered to be past their best?. i know there is a gradual reduction , and i have been told to replace after 6 months.
What do you think, and how do you decide ?.
Any advice greatly appreciated.
