OSRAM NAV-T Super (Son-T Plus) 400W 4Y

VIALOX® NAV® SUPER 4Y® lamps are the brightest and most economical high pressure sodium lamps:

  • Up to 20% higher luminous efficacy (up to 150 lm/W) than standard NAV® 4Y® lamps
  • The same colour properties and applications as standard NAV® 4Y® lamps

Practical advantages over NAV® 4Y® lamps:

  • Existing installations: Higher lighting level for the same energy costs
  • New installations: Smaller number of luminaires and lamps, hence lower investment and operating costs
