Time to Replace Bulb?

[spf9992001]

I have a 12 gallon nano cube. I thought that the 24 watt PC bulbs were supposed to be changed out about every 6 months, or so...

I went down to the LFS and bought a couple of replacements and after looking at the packaging from JBJ, I see that they recommend replacing the bulbs every 14-16 months.

What do you all recommend?

Thanks,

Jake

i go every 10 months, if you have no problems just wait.

You can run PC bulbs for 1yr,@ 9hrs a day.

Thanks everyone. I'll put the replacements on the shelf for a while.
