Although it was also laundry-and-house-cleaning day, I couldn’t resist giving it a go. And in particular, seeing how it would pitch against the bank of UV tubes I’ve had around for years. Here are my expectations when I ordered it: (1) higher total luminous flux, so shorter exposures, (2) better collimation, so less bleed and better detail rendering. How does it pan out, you think?
