Let me check when I get back home. I've got a few boxes of the Silverchrome and I don't think I've thrown the data sheets away (tbh, I never look at them).
I'm a uni prof, so the first semester (April-July) was completely online, and the second semester (Oct-Jan) was as well, although I had to go in once a week for a single class (the university's way of bowing to parent/student pressure to have some kind of f2f interaction - so one class a week was allowed). This year, I've basically been back to work as usual, although of course everyone has to be masked up and temps are taken upon arrival on campus. Windows and doors are kept open which is good on the one hand, but sucks on the other as most teachers need to use a mic now to be heard through their masks, which means a lot of distracting noise coming into the class. But as a teacher I much prefer teaching in person than online, it's much easier to see if the students need help, are progressing at a good rate, and if they actually understand and laugh at my jokes.
