 A smart light bar — illuminates dark places on-demand by gently powering-up/down a LED stripe depending on the ambient light level and a detected human presence.
 
 Hardware core is a ESP32-H2 SoC connected with an VEML7700 ambient light sensor and a small but effective LD2410 radar based presence sensor.
-This automatic floor light is completely self-contained.
+This automatic light is completely self-contained - just needs a 12V power supply.
 
 _It does not use Wifi or Zigbee features of the ESP32-H2 SoC and does not connect to a smart home system with that firmware here - but one may add such a feature smoothly, of course._
