Conjuring up unique lighting moments - colourful colour filters from the PUK series Practical filters for the PUK luminaire series can be ordered in the colours magenta, blue, yellow, green and red. For mounting, the selected colour filter is simply placed between the housing and the lens, where it is flooded by light and conjures up fascinating light images that transform the room into a special oasis of well-being. The filters can be combined with all luminaires of the PUK series.
