There is provided an illumination system () for cultivation of aquatic animals. The illumination system () comprises at least one light source () emitting light, at least one light driver () arranged to drive the at least one light source (), at least one light sensor () providing illuminance data for at least one point of interest () in said illumination system (), and a controller (). The controller () is adapted to provide control signals to the at least one light driver () driving the at least one light source () to emit light of a desired illuminance at the at least one point of interest (). An ambient light sensor may be applied to determine control signals also in accordance with ambient light data.

A lighting control module comprises an interface for receiving a dimming setting and a memory for storing the dimming setting. Based on the dimming setting, an output circuit generates a dimming control signal for application to a conventional dimming interface of a lighting driver circuit. For this purpose, power is received from the dimming interface. This provides a simple to use way to implement a controllable brightness, which makes use of a dimming driver but used for a luminaire which does not need to be within a networked dimmable system architecture.

A low-cost HID lighting system () comprises: &#x2014;an HID lamp () having an aspect ratio less than 6; and &#x2014;a resonant electronic driver () for driving the HID lamp, the driver being designed for providing alternating current to the lamp and including a control device () for determining the current frequency. The lamp has a frequency spectrum containing at least one arc-shaping acoustic resonance frequency as well as unwanted acoustic resonance frequencies. During normal operation, the lamp is provided with frequency-modulated lamp current so that the lamp current has a relatively broad power spectrum within a range between kHz and 200 kHz, so that said arc-shaping acoustic resonance is triggered while said unwanted acoustic resonances are avoided, irrespective of lamp orientation.
