Economic and elegant sober

The document is written only in English which should give anyone trouble, given the complexity of operations:
- Install the sensor in a sufficiently sunny, the manufacturer of the board is to expose it to direct light from the midday sun
- Select the operating mode using the light switch from fixed, flashing and off

At dusk a sensor triggers ignition of lights, since the switch is not, of course, to off ...

I appreciate the simplicity of lighting: white, sober, not dazzling, elegant. The garland was installed around a large conifer and subtly embellished the garden at night.

I hope that the life of the sensor and the battery will be long, this question unanswered apart the product gives full satisfaction.
