How do you troubleshoot a high pressure sodium light?

The most common problem with a high pressure sodium light is the bulb. The first course of action is to simply change the bulb. Observe the interior gas tube for any signs of discoloration. If the tube is black, the bulb is definitely burned out.

Are high pressure sodium lights being phased out?

Phasing out A number of popular lighting types will have to be phased out by 2017 including selected ‘standard’ high-pressure sodium (including retrofit), high-pressure mercury, and standard performance metal halide.

Why do high pressure sodium lights cycle on and off?

High Pressure Sodium Lamps Normal end-of-life is usually indicated by the lamp cycling on and off. As the lamp accumulated burning hours, its operating voltage increases, eventually becoming higher than the voltage supplied by the ballast. The lamp extinguishes and cools. The ballast restrikes the arc.

How do I know if my HPS bulb is blown?

If you notice darkening on the base and it will be your fourth harvest, there’s a good chance the bulb is close to burning out. Another telltale sign of burnt-out HPS bulbs is when they flicker a lot or shut off completely. It’s best to replace them because this can lead to a decrease in spectrum colour.

Do high pressure sodium lights use a lot of electricity?

High pressure sodium fixtures are not as energy efficiency as LEDs. In fact, LED bulbs use between 40-75% less electricity than a HPS fixture.

How long do high pressure sodium bulbs last?

High Pressure Sodium lights maintain their luminescence fairly well with 90% still available halfway through their lifespan (around 12,000 hours). HPS bulbs typically emit 80% of their original rated output at the end of life (around 24,000 hours).

How often should I replace HPS bulb?

HPS (High Pressure Sodiums) bulbs need to be replaced once a year with a 12 hours on 12 hours off cycle. HPS bulbs lose 20% output in a year, so you lose around 20% of your yield. MH (Metal Halide) bulbs need to be replaced every 8 months on a 18 hour on 6 hour off cycle.

How long do HPS bulbs last?

You’ll get a good 24,000 hours out of an HPS lamp. When they do start to degrade, though, HPS bulbs tend to depreciate in their blue spectrum output first. They typically need to be replaced about every 10 to 14 months.

What is an S62 bulb?

Lumalux – High Pressure Sodium – ANSI S62 – Medium Base – LU70/MED. 5.0. (2) The SYLVANIA LUMALUX high pressure sodium lamp is ideally suited for street and area lighting applications where high efficiency and long life are desired. Unprotected arc; can only be used in enclosed fixtures.
