Sounds like maybe a ballast problem. May be time to change either that or
the whole light assembly since the ballast may cost more than a whole new
light.

Hello
I have an old Marineland Eclipse System 3 for a 29 gallon hood
When I plug in the light, there is a slight buzzing noise from the AC
adapter.

Is this normal?

Thanks

K
