Some models use a standard Edison E26 socket (the table lamp ships with an LED E26 bulb), while other items have non-removable, integrated LED modules powered via USB.
It varies by model. Some lamps require basic adult assembly (may require simple tools), while at least one model arrives fully assembled with no setup required.
The table lamp is listed as ETL Listed. Certification details for the other lights are not clearly specified in the available product information.
The table lamp lists a polyester shade with an MDF and metal body. The wall and panel lights are described as plastic.
Options include a desk/table lamp with a base, wall-mountable novelty lights that come with screws and anchors, and panel lights intended to be arranged on a wall using adhesive and linking cables.
