high pressure sodium lights troubleshooting

So a higher wattage light is going to give you more light on your specified area than a lower wattage light. After visual inspection, many growers find that some lamps in their greenhouse either aren’t operating or aren’t doing so at full brightness. Failed IgnitorA less common problem is failure of the ignitor. Wait about 10 minutes to see whether the light illuminates. High Pressure Sodium Applications HPS lamps, unlike most metal halides, do not require enclosure except to prevent moisture from accumulating on the lamp. This partial failure is not always visually apparent, and lights continue to function at reduced efficiency for extended periods of time. Twist the wire nut counterclockwise while pulling it out to remove it. Pull out your owner's manual to make sure the accessories are appropriate for your lamp. If the MH lamp starts and a new HPS lamp does not start, the ignitor probably needs to be replaced. Capacitors also can partially fail. It this doesn't correct the problem, then the sensor would need changing. In lighting, the higher the wattage, the higher the light output. High pressure sodium bulbs ("lamps") are an old standby for lighting that's still used today in spite of so much talk of LED lights. For any school, hospital, or retail facility, energy is a huge cost driver. All Rights Reserved. Replace lamp. Ballast replacement kits cost $130 to $150, and it can be cost effective to replace the ballast rather than purchase a new lamp. Fixtures with partially failed capacitors have a power factor of 0.70 to 0.80. I'd try cleaning the sensor with a damp cloth and see if that gets you going again. Five to 10 percent of the HPS lamps we’ve purchased in the past 25 years have had partially failed capacitors. Here, the fixture starts and runs continuously but comes up to only 10-60 percent of its maximum brightness. Visually inspect the lamp for proper connections and contacts. If the bulb is black inside the glass or broken, you need to replace the sodium bulb. Sunlite 03620-SU LU150/MED High Pressure Sodium Light Bulb, 150 Watts, ED17/MED, Medium Base (E26), ANSI Code S55, 15000 Lumen, 20000 Life Hours, Clear, 2100K 4.4 out of 5 stars 424 $15.99 $ 15 . High-pressure sodium lamps (also known as HPS Lamps or HPS lights) are a type of sodium lamp that is widely used in industrial lighting and many public outdoor areas. Most of these lights last a long time, so 2-1/2 yrs is really nothing in the terms of how long they should go without a problem. If screwing in a new bulb does not solve the problem, the lamp must be taken down and disassembled. The HPS light fixture was developed by General Electric and made its debut in 1964. Place a small cardboard box over the photocell eye so the box rests on the top of the fixture. Check the porcelain holder for any signs of deep cracks or breaks. These lamps reduce growth and increase electric consumption. Like Metal Halides, High Pressure Sodium lights are omnidirectional, which wastes light and makes them less efficient. The most common problem with a high pressure sodium light is the bulb. They lose roughly 15% of their heat emissions which adds to their inefficiency. Let the light cool for about 20 minutes. High-pressure-sodium lamps and metal-halide lamps do not exhibit obvious symptoms when power is off. Metal halide lamps do not require an ignitor to start, so the test for a failed ignitor for an HPS lamp is to screw in a metal halide bulb of the same wattage and see if it starts. Some other critical factors at play here are things like: the size of the area … If the MH lamp starts and a new HPS lamp does not start, the ignitor probably needs to be replaced. This failure cannot be measured with a standard volt-ohm meter. Ballast for the lamp to provide a high starting voltage, lamp conduction.

She loves writing about careers for busy families as well as family oriented planning, meals and activities for all ages. Pull the bulb straight out of the fixture. A big driver behind their use is their… This meter must be connected in line with the lamp, and the light should be at full brightness before you take the measurement. An incorrect lamp-and-ballast combination will exhibit the same symptoms as a bad bulb. AgeOld bulbs fail by cycling on and off. Fix your H.P.S. Turn off supply voltage at breaker before accessing fixture Wiring Compartment. The door swings open in the opposite direction of the lock on hinges. Failed CapacitorThe second most common failure is the capacitor. It’s easy to screw a new bulb into the fixture. In our experience, the partially failed capacitors have 50 percent of their rated capacity (13 microfarads instead of the normal 26). Some models do not include a photocell and switch on and off manually. The lifetime of a capacitor depends on how often the lamp is started and the temperature of the capacitor (the warmer the temperature, the shorter the lifetime). The first course of action is to simply change the bulb. … Field wiring connections should only be made by qualified personnel. Observe the sodium bulb for darkness inside or breakage. A box from a macaroni-and-cheese kit or other dinner side dish works well. If you’ve invested in the lamps, you should be sure they are running effectively. This will eliminate any visual or connection issues with your high-pressure sodium ballast. Grasp the wire nut with the other hand. Also works for Metal halide. Since high-pressure sodium lamps have mercury and sodium inside it needs to utilize a high-voltage pulse to ignite the lamp, which the ignitor provides. Confirmation of a partially failed capacitor can be made by measuring it with a capacitance meter ($20 to $80). Operating HPS lamps at less than full output, however, produces color shift, changes in CRI, and reduced lamp efficacy. ballast. The fixture lock may be on either side of the fixture depending on the brand and model of light. © Copyright 2020 Hearst Communications, Inc. Observe the interior gas tube for any signs of discoloration. In high pressure sodium, the dark gettering material in the neck of the bulb near the base will turn white or disappear. Mary Lougee has been writing for over 10 years.

The power factor of a normally functioning lamp with a new bulb is 0.97 to 0.98. 2. 2249 S. McDowell Ext. Fixtures with bulbs nearing the end of their lifetime have power factors of 0.90 to 0.94. Here’s a list of the most common HPS lamp failures — and a little technical savvy to diagnose and repair them. Replace sodium bulbs with either the same type of bulb, which is either low-pressure or high-pressure. Clean any corrosion off connections with a wire brush, twist the wires together and replace the wire nut. If you’re not electrically inclined, work with your lighting manufacturer or an electrician to diagnose problems and replace component parts. Defective BallastIf a new bulb, ignitor, and/or capacitor do not make the fixture work, then the ballast is probably defective. Dimming is limited to about 50% of full light output.

I have a high pressure sodium vapor lamp that is going onand off. Metal halide lamps do not require an ignitor to start, so the test for a failed ignitor for an HPS lamp is to screw in a metal halide bulb of the same wattage and see if it starts. If the sodium light does not include a photocell, ignore this step because the light should be in working order. High-pressure sodium lamps are widely used in greenhouse production, but they require maintenance for peak efficiency. Close the fixture door. Refer to wiring diagram on ballast label for proper component connections (typical connections illustrated above). A less common problem is failure of the ignitor. Check the wire nuts connecting the electricity to the light. Hold a wire junction in one hand. Provides focused illumination for outdoor use in residential and light commercial applications. While upgrading to LED provides a lot of benefits, high pressure sodium (HPS) lamps still provide some of the most efficient lighting available. Cover the eye with any other thick material to block light for this test. Be sure to cut off power to the lamps before working with them for safety reasons. There are two kinds of sodium lights: Low Pressure (LPS) and High Pressure (HPS).These lamps are mostly used for street lighting as well as industrial uses.

For safe operation: Place a ladder or step stool near the light, if need be, to acquire height to reach the light fixture. high pressure sodium ballast output voltage use high pressures of sodium, in an excited state, to generate light. High-pressure sodium lamps are widely used in greenhouse production, but they require maintenance for peak efficiency. Each of the two wires should be wound tightly together with no signs of corrosion in the junction. Step 3 - Check Accessories. Defective Ballast If the capacitor is enlarged, it has failed and needs replacement. If the light does not come on, the photocell is defective and needs replacing. HPS fixtures quickly picked up speed and by 1970, many parking lot lights and street lights were adopting the new lighting technology. High pressure sodium continued If water is the culprit, why then the center light stays eluminated and the left and right mounted lights from center are the only lights turning off and on. High Pressure Sodium Flood Light General Purpose Outdoor HPS by Lithonia Lighting. This action enacts the transformer to illuminate the bulb as it does at dark. If the light comes on and then goes off a few minutes later, first replace the lamp. Remove the bulb by turning it in a clockwise direction. Step 2 Check the specifications on the ballast. The door will make an audible snapping noise when it closes fully. Petaluma CA 94954       P: 855-727-5483 | F: 877-262-6050 |  Email Us. I will still blow the water out of the conduit and try this but don't comprehend the center light without malfunction if water being the culprit. An ignitor is used when high pressure is necessary to strike an arc through certain materials and get the temperature up very quickly inside it. high pressure sodium light fixture troubleshooting, has power but light bulb doesn't come on? Common high intensity discharge light wattages used for parking lot and area light fixtures range from 100 watts to 1000 watts. If it is, use a meter capable of measuring the power factor of the lamp, such as the Kill-A-Watt meter (about $30). 4. Wrong Ballast Place a ladder or step stool near the light, if need be, to acquire height to reach the light fixture. High pressure sodium ballasts for lamps provide stable current use of the inductive reactance of the ballast, and other pipe lit work. HPS light costs differ based on the particular fixtures, but are cheap compared to LEDs. Placing a cardboard box over a photocell eye blocks light from the eye to trick it into assuming it is dark. Look for broken arc tube or loose metal parts. An outdoor sodium light that does not illuminate may have a faulty bulb, wiring inconsistencies or need a replacement photocell. A magnetic ballast, in series with an AC current voltage source, supplies the lamp with a near-constant stream of current.Sodium ballast lamps are widely used in streetlights and security lighting, as well as applications requiring high color rendering. New capacitors are about $25. Outdoor sodium lights are either low-pressure or high-pressure lighting to illuminate large areas with bright light. light fixture high pressure sodium, I've change 3 different light bulbs, but non of them comes on, tester sounds that has power. Ideal for walkways, yards, patios, play areas and driveways creating an inviting exterior … This type of lighting is effective as a security light with a photocell to illuminate at dark and remain on until daylight. In fact, they're roughly as efficient as LEDs in terms of their light output for each watt of energy used. Turn off the power to the light at the switch or breaker box to prevent burns. High-pressure sodium lamp based ballasts are a great way of limiting or controlling the amount of input that is consumed by the lighting installation of high-pressure sodium lamps it's fixed to. HPS bulbs should last four to six years, depending on the number of on/off cycles and hours of use. Update: is not in a photo cell, just in a clock, Sodium Lamps were first produced commercially by Philips in Holland in 1932. High Pressure Sodium Bulb has Short Life or otherwsie is Not Quite Right: You can have the right wattage but still have the wrong bulb for the ballast. Turn on the power at the switch or breaker box. A leak in the outer bulb will cause oxidation of the metal parts inside. Verify proper types and ratings. Repeat this process for the additional connection in a wire nut. These lamps … 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.. Two varieties of such lamps exist: 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. It takes the same amount of time to replace the ballast as it does to replace the capacitor (40 to 60 minutes to take the lamp down, replace the components and rehang). HPS fixtures with a partially failed capacitor have a lower light output, a lower power factor and reduced efficiency. I purchased and installed a new 100-watt high-pressure sodium lamp (and left the new sensor in) and it was like a new light … These ballasts use compressed high-pressure sodium to produce an arc to generate heated energy to for the lamps fixtures and enable lighting of High-Pressure Sodium Lamp derived installation. Turn off the power to the light at the switch or breaker box to prevent burns. After visual inspection, many growers find that some lamps in their greenhouse either aren’t operating or aren’t doing so at full brightness. 400w, 600w, 1000w. She holds a Bachelor's Degree with a major in Management and a double minor in accounting and computer science. HPS lamps may be dim if the supply voltage is low. A very first appearance at a circuit diagram could be confusing, however if you could review a subway map, you can check out schematics. They are commonly used in public parking lots, roadways, and other security areas.
