T5 bulb life spand

[leonard2k]

i wonder how often does you all change your T5?

mine is 1 year plus no spoil, but is it good to change?

Fish only tank shouldnt matter as long as it still working..but for corals (photosynthetic), best to change minimum once per year. The tubes suffer spectrum shift overtime .

depends what you keep, and what fixture you using.

SPS - 6 month for ATI fixture which will overdrive the bulb, other brand can be 8 month

although the tubes still working, the intensity might have reduced and the spectrum might be shifted.

depends on what tubes you are using and the corals requirement. Usually is 9 - 12 months for optimal performance.
