What does a high pressure sodium bulb look like.

Check the porcelain holder for any signs of deep cracks or breaks. 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. 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.

Sodium mercury and xenon are usually used inside the arc tube. The arc tube has a high pressure inside for higher efficiency. 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. 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.

If the tube is black the bulb is definitely burned out. Observe the interior gas tube for any signs of discoloration. 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.

Most high pressure sodium light systems normally last between 12 000 to 24 000 hours.
