About

4K5 LightControl

Features
Read full description

The Light Control app improves efficiency, flexibility and convenience when working on site. It allows 4K5 work lights to be controlled from a smart phone over a wireless connection. The output of the light can be dimmed in five levels from 20 % to 100 % for optimum and quick adjustment to the actual situation and task. In addition to the display in per cent, the set light level is easy to identify from an easy-to-read graphic. Four work lights can be connected to the app at the same time. It is also possible to operate a work light from two smart phones with synchronised operating status. For work lights running from a battery, information on the charge is provided by a colour and per cent display. The power consumption can be effectively reduced by adjusting the light output to suit requirements as only as much electricity is consumed as is required to complete the task. The work lights can be quickly switched off remotely when leaving the site.
