5 Colour LED Engine


The 5 light colours of the Sirius range (red, green, blue, warm white, and cool white) enable full colour mixing and tuneable, high quality white light from a single source.

Dynamic Power Regulation


Sirius luminaires automatically manage the amount of power that each channel uses. This boosts the light output when using fewer channels at once, resulting in far brighter and more saturated colours.

DPR also continuously monitors the LED temperature and manages the light output to prevent the luminaire from overheating.

Power & Data on 1 Cable


IPM² is a revolutionary driver technology from GDS that can provide both power and 512 channels of DMX control data over legacy 2-core mains cabling.

As well as multichannel control, IPM² is capable of two way data transmission. This means that it can send the thermal data from DPR and other sensors back to Drive Hub.

Saturated colour and tuneable white

Red, green, blue, warm white and cool white emitters mix in one fitting, so Sirius can flood a space with saturated colour or tuneable white from 1800K to 4000K.
