mh tubes lasts anywhere between 10000 to 20000 hours.
is there noticable reduction in light intensity or are your plants growing much slower?
if there is nothing wrong, just leave it.
no need to fix something that isn't broke.

My MH Bulbs has been in operation for 8 hrs daily for the last 1.5 years. Wonder how long more before I need to change. Whats your experience?
