Function:
Initially, the LR20 batteries are inserted by turning the lamp head by about a quarter turn and pulling apart. After inserting the batteries you need to install the device only on the selected course and it works automatically.
Once the device is a small movement registered turned the light. The device was activated directly in our basement when we had only slightly enter the visible area. Dropouts never existed until now.
In addition, in the spotlight, a photocell is fitted, which prevents activation of the headlight even with brightness, which prevents unnecessary power consumption.
Conclusion:
All in all I'm very happy with the headlights and look forward with laden arms to enter the basement without the light to turn it on only awkward!
