T5HO Lifespan

[patrick8929]

how long will an 18" T5HO bulb last for? im getting a bit of an algae bloom and i think one of the bulbs is going bad, should i replace them all i think its about 7 months old maybe 8 i dont remember when i got it exactly

The general rule of thumb is about 18-24 months per lamp. If you have an algae bloom, I'd look elsewhere before the lamps if they are only 8 months old.
