Um - why not get a control group? I'd happily volunteer.
I mean, it might not be perfectly randomized, but you can at least watch for confounders from just being in this community, or introspecting for data collection, or whatnot.
Well, I've got a grand total of 3 emails and no PMs so far. I was going to ask questions like: how much time and money did the lights cost to set up, do you feel like it works better than coffee, have you seen any decline in its effectiveness, etc. No heavy data collection, just a survey about peoples' experiences.
