It's small enough to fit in my Raspberry Pi case, it's easy enough to operate in Home Assistant - and it is blindingly bright. Literally, I was blinded for a few hours after playing around with it for a short minute or so. I can't think of a better possibility to add so much lighting to a Pi with so little real estate. Not to mention how inexpensive it is! I can just recommend it for anyone who wants to add well visible notifications, a friend even suggested lighting a dance room with it. Well, it has the needed oomph for that! Very nice product indeed.
