The Solution
HOW WE ACHIEVED THE RESULT
Instead, the organisers decided on an alternative solution, that was suggested by Holophane, of upgrading the existing lighting. Since its inception, the curling rink had been illuminated with Holophane Prismalume metal halide luminaires. These provided good levels of illumination and colour rendering but it would not have been possible for them to provide the 1,500 lux required for televising.
The solution was an upgrade to replace the 36 existing 450W luminaires with 380W LED Haloprism units. Changing them on a one-for-one basis greatly reduced the cabling and installation costs of the upgrade.
