Does anyone have a Xiaomi USB LED light?

Any suggestions for using these? I have this disorder, when something is good quality and heavily discounted, I usualy end buying it too many. So I bought 10 of these at 1,09 a piece (verified originals). Although I still think the mini LINK for 1.1$ + flexible usb extension for 1.88$: LINK is more usable and worth the price difference over xiaomi.
