[alt-photo] Re: NuArc UV units question

[Amy Holmes George]

Hi Paul,
I also have the NuArc 26-1K unit, and I just timed it at exactly 4 minutes for 120 units. I'm using the factory recommended bulb (GW-114), but it is not a fresh one (can't quite remember when I replaced it). Anyway, I thought this might help give you a working reference.
