Do T5 bulbs have a shelf life if not used?

[Hammer100]

I have a coral plus bulb that i would like to use but its over a year old. Never been used.

Its fine.

Remember it will need a burn in time too, don't get discouraged if the color doesn't seem right on first firing.

great thanks...i know the PAR is supposedly 2 times higher when new....should i cut back my time schedule for a while?

I am using them as supplement to my LEDs. They run for 6 hours a day

It probably wouldn't hurt to cut I back at first but I doubt it'd be an issue if you hadn't, especially one bulb.
