Providing effective lighting to MATISA. MATISA design and build track construction and maintenance machines that are acknowledged worldwide. TYRI was asked to provide high quality, professional illumination for their Ballast Regulator R21 (Track Maintenance Machine). The main challenge was to create an even illumination of the track under the machine, the embankment (3m) and the conveyor belt. Additionally, the machine operator was required to observe the ballast flow from the cab without the lights creating glare or reflection from metal or fine dust.
