Morning, welcome to ReefBase.
Well that's a Tunze powersupply, but it's not one of their lights that I recognise. Are there any other bits of text written on/in the remote or around the display on the unit?
It could also be that somebody just repurposed a Tunze powersupply.
edit- yeah that's the powersupply from a Tunze 6105 wavemaker, so not the original one for that light.
