High Pressure Sodium Lamp Lifetime

High pressure lights have a life expectancy of 16 000 to 24 000 hours while low pressure sodium lights should run for 12 000 to 18 000 hours.

High pressure sodium lamp lifetime.

A sodium vapor lamp is a gas discharge lamp that uses sodium in an excited state to produce light at a characteristic wavelength near 589 nm. Cri and reduced lamp efficacy.
