They outlast their usefulness. I changed out my PCs one, thinking that I was wasting money, changing them out before they blew.... Turns out, within a few minutes of turning the new ones on, I had Zoas that I only thought had been opening up, and was twice as colorful.

As much money as this hobby costs, replacement lamps aren't the place to try to scrimp. It's nice to see what you've been working so hard to achieve.

my thoughts....
