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.
