Gain a clear overview of your rack mounted gear thanks to the Adam Hall 87451SMART sensor light. Loaded with eighteen white LEDs, an extra-long cable and a dimmer, this efficient light is triggered by a motion sensor. Adjust the brightness via the push-and-hold button or switch the light off completely. Once you've hit your favourite setting, use the memory function to save it for next time - even if the power is turned off. Motion Sensor with Sleep Mode What makes this rack light super special is the onboard motion sensor which, when no motion has been detected for a certain period of time, puts the light into sleep mode. Set the sleep mode timer yourself and keep your setup neat and energy efficient. This Adam Hall design comes with an extra-long two-metre cable and around the rear, a cable pull-relief has been fitted just in case.
