The construction seems sturdy deck that supports LEDs and the electronic board, is metallic. Good protection against moisture (attached). Easy connection. No special heating since its commissioning. According to the leaflet, the batteries provide approximately three hours of light. I have not tested .. The battery pack is classic. Used in a bathroom without windows, the LEDs provide a comfortable emergency lighting safely without any manipulation.
