A remote follow spot system includes a remote controller that has separately movable parts that are movable in two orthogonal directions, and a display attached to one of said two separately movable parts. The display receives a video feed from a controlled light, that is controlled to move in the same directions as remote controller. The display hence shows the field of view where the light is pointing. In this way, an operator of the follow spot can control the light without physically being near the light.

An energy-efficient, compact and cost-effective solution for driving a number of high-power LED groups for lighting applications includes using a single switching power supply together with LEDs connected in series and/or in parallel and pulse width-controlled switches in parallel across the individually controllable LED groups. If the switch of an LED group is ON, the LED group will not light up. If the switch is in the OFF position, the full current of the power supply will pass through the corresponding LED group.
