ZDNET reviews the Poplight wall sconces, which are renter-friendly smart lights that stick to the wall without causing significant damage. The lights, which cost $100 per lamp, are currently on sale at Amazon's Big Spring Sale for $84, a 15% discount. ZDNET's reviewer praises the ease of assembly and flexibility of the Bluetooth-enabled devices. Despite their inconvenience, the lights can be used to create a cozy ambiance in your bedroom while reading or watching TV. The reviewer acknowledges that the app experience is lacking but commends the quality and design of these products.
