Looks like the same seller is on Etsy.
This one could be one of the best prices on a true tactical light, with the right diameter to fit on a rail mount adapter. Uses two CR123A batteries.
80 lumens, apparently?
They have dimmable candelabra bulbs for a decent price.
Sadly, the ZigBee protocols are incompatible. That leaves trying to do OpenHAB or similar with Raspberry Pi if I want to integrate Ikea cheap gear, but it might mean a cheaper Z-Wave Vera hub.
closet lighting?
adjustable color tone by switch, maybe could work with TRADFRI hub?
IKEA - NYFORS, Floor/reading lamp, You can easily direct the light where you want it because the lamp arm and head are adjustable.Fabric shade gives a diffused and decorative light.
