Normally every 12 months. But some ppl do it around the 8 months, it really depends on the person.

12 months

 

[George Farmer]

Approx. 12 months. I hear T5 last longer than T8 but have not had T5 long enough to confirm.

Not sure on metal halide either.

 

[Miss Wiggle]

MH's should also be changed yearly

interesting and i don't know if this applies to plants but i'll tell you anyway as it may well do, on a reef set up when you put a new MH bulb in you should reduce your photoperiod and build back up slowly, corals can go into shock from the change in spectrum and intensity given by a new bulb and it can damage them if not done carefully.

 

[George Farmer]

Yes, plants take time to adjust to new spectrums and intensities too.

I've got T5s that are over two years old now.

I really need to replace my bulbs.
