Description

Supply and installation of 13 LED luminaires, each measuring c1.5 x 0.4 meters, with the light output per unit to be at least 22,500 lumens, although dimmable to lower output as required. Light output to be tuneable within a range of 5000K to 6500K. Colour rendering must be rated at CRI 99 (R9 of 94 and R12 of 96.5) whatever the level of output. It is desirable to have some sort of diffusing of the light which neither itself degrades nor reduces the CRI and output level. The luminaires will need to be able to rotate horizontally up to approximately 320degrees, and lockable at any given rotation angle. We require a lamp life of c 50,000 hours.
