As I understand it UV
bulbs do not last long. Not sure what "long" is though.
I also understand that $10 bulbs (which this approximately is) are usually not any good, regardless.
And I suspect the flow rate past it is too high regardless.
Is all that correct?
Is there any point in replacing them?
In fact, would it be better to remove the bulb and case, and seal off the socket, giving more room for flow through the column, and not bother with the UV
Anyone done that?
