What Does A High Pressure Sodium Bulb Look Like

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.

What does a high pressure sodium bulb look like. The most common problem with a high pressure sodium light is the bulb. Both bulbs have a relatively long lifespan though a high pressure sodium bulb will last slightly longer up to 6 to 18 months at a usage rate of 12 hours per day 2 to 6 5 thousand hours total while a metal halide bulb will last for 6 to 12 months at a usage rate of 18 hours per day 3 to 6 5 thousand hours total.

If the tube is black the bulb is definitely burned out. The arc tube is made of aluminum oxide ceramic which is resistant to the corrosive effects of alkalis like sodium.

The first course of action is to simply change the bulb. The arc tube has a high pressure inside for higher efficiency. Check the porcelain holder for any signs of deep cracks or breaks. A 400w bulb can easily cover a gardening area of approximately 15 square feet while a 1000w bulb can be used on a growing area of around 7x7 feet.

Low pressure and high pressure low pressure sodium lamps are highly efficient electrical light sources but their yellow light restricts applications to outdoor lighting such as street lamps where they are widely used.
