These are UV and PFr for filling out the spectrum on a couple of Heliospectra 601Gs. It’s for an experimental platform I’ve been piecing together, Airpumpless Sluckets . I’m looking to run, log, and automate various experiments I have in mind. Being able to control the spectrum to some extent is a plus in this way and, as such, the odd wavelengths chosen.
The bars work fine and won’t be looking to return them. Just not terribly impressed with how they were packaged 
I like your choice in the Greenhouse and Anthospec. Do you have a post describing how you are using them?
