Technology and product design

PhotoSynergy (PSL) has developed and patented a fibre illumination system called LIGHTPATHLIGHTPATH can be used for a wide range of applications from guide path illumination through to the extremes of challenging, hazardous and submerged environments. The LIGHTPATH concept is based on a side-emitting flexible fibre that creates a continuous line of light up to 75m in length. The fibre carries no electrical power, only light, and requires less than 7W.
