High-pressure sodium lamps VIALOX NAV-T SUPER 4Y
Clear tubular NAV lamps enable light to be directed with great precision. For new street light installations, this means that the mast spacing can be greater. This applies in particular to NAV-T SUPER 4Y lamps with their extremely high luminous efficacy. Potential savings are considerable.
VIALOX NAV-T SUPER 4Y lamps are among the brightest and most economical high-pressure sodium lamps. 4Y stands for 4 Years. With VIALOX NAV SUPER 4Y lamps, the relamping interval for groups of sodium lamps can be extended to four years.
Benefits
Compared with standard high-pressure sodium lamps:
-Up to 25 % longer life
-Greater reliability
-Up to 20 % higher luminous efficacy
-Greater mast spacing
-Better lumen maintenance
Applications
-Industrial installations
-Streets
-Tunnels, underpasses
-Car parks, courtyards
-Parks and gardens
