Typically these lights are used on sides of industrial buildings and in some street lamps. A wide variety of high pressure sodium lamp options are available to you, such as etc. The lamp works by creating an electric arc through vaporized sodium metal. The xenon gas which is easily ionized, facilitates striking the arc when voltage is applied across the electrodes. Commonly, a shift towards blue and/or violet can be observed. The higher efficacy of HID lamps compared to halogen units means longer burn times for a given battery size and light output. We also offer our own 30 Day Purchase Satisfaction Policy, For any other questions, we staff an expert team of specialists to handle your questions and requests. Another phenomenon associated with HID lamp wear and aging is discoloration of the emitted light beam ("fading"). They provide an intense light which is used in various commercial and industrial settings. This makes them particularly effective as photographic safelights. Like fluorescent lamps, HID lamps require a ballast to start and maintain their arcs. Benefits. The effect of this is that the lamp glows for a while and then goes out, repeatedly. In these applications, a ballast failure isn't just an inconvenience, it's a public safety hazard. Mercury lamps also require special waste disposal, depending on location. Although LED and High-Pressure Sodium are both popular options for area lights and outdoor fixtures, let's explore the difference between the two and why you should consider LED lighting. The heat generated by the arc then vaporizes the mercury and sodium. This lighting method provides a wide spectrum of color that other lighting options can seldom equal. Once the arc is started, it heats and evaporates the metallic admixture. SON-T Pro is a cost-efficient and reliable solution in High Pressure Sodium.

Contact your customer service support team about products, services and more. Many modern vehicles use HID bulbs for the main lighting systems, although some applications are now moving from HID bulbs to LED and laser technology. What's so special or different about them? HID lamps have made indoor gardening practical, particularly for plants that require high levels of direct sunlight in their natural habitat; HID lamps, specifically metal-halide and high-pressure sodium, are a common light source for indoor gardens. These high efficiency lights produce a golden white color and are used for interior industrial applications, such as in… Indeed, high pressure sodium (HPS) lights are generally unmatched in terms of energy efficiency. High-pressure sodium lamps tend to produce a much whiter light, but still with a characteristic orange-pink cast. High pressure sodium lamps contain mercury and sodium. Beginning in the early 1990s, HID lamps have seen applications in automotive headlamps. Varieties of HID lamp include: The light-producing element of these lamp types is a well-stabilized arc discharge contained within a refractory envelope arc tube with wall loading in excess of 3 W/cm² (19.4 W/in²). When deciding high pressure sodium vs LED, it’s first best to describe each one in depth, since both produce light in different ways. Plant Growth. 2140 Merritt Dr, Garland, TX 75041 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. High Pressure Sodium Lamp (HPS Lamp) The HPS lamp is the most ubiquitous lamp for street lighting on the planet. Mercury-vapor lamps were the first commercially available HID lamps. High Pressure Sodium High Pressure Sodium Ballasts at 1000Bulbs.com Because they are second only to low pressure sodium as the most efficient and longest lasting of all HID lighting sources, HPS lamps are used streetlights, parking lot lights and other outdoor lighting fixtures more than any … The heavy duty transformer or ballast is also long lived if the bulbs are changed out before they burn out. HID lamps are also used in lamps for underwater diving. We also offer special conversion metal halide bulbs that can be used with fixtures intended for high pressure sodium light bulbs. High Pressure Sodium Vapor (HPS) lights are a specific type of gas-discharge light (also known as a High Intensity Discharge, HID or arc light). Sodium bulbs can last up to 20,000 hours. Difference Sodium Vapour Lamp Mercury Lamp Light Source Works by electric discharge (passage of electricity through sodium vapours at high/low pressure) Works through the. High-pressure sodium (HPS) lamps have been widely used in industrial lighting, especially in large manufacturing facilities, and are commonly used as plant grow lights. Eventually, with the arc extinguished, the lamp cools down again, the gas pressure in the arc tube is reduced, and the ballast can once again cause the arc to strike. Alibaba.com offers 5,601 high-pressure sodium lamps products. Use of this site signifies your acceptance of 1000Bulbs.com Terms and Conditions and Privacy Policy Woods L1741 150-Watt High Pressure Sodium Dusk to Dawn Security Light with 12-Inch Acrylic Refl… A big driver behind their use is their… As they heat up during operation, however, the internal gas pressure within the arc tube rises and a higher voltage is required to maintain the arc discharge.

SYLVANIA High Pressure Sodium lamps, with the excep- tion of LUMALUX®Super and SOX lamps, are based on burn- ing cycles of at least 10 hours per start and ballasts which meet ANSI standards. The amount of gamma radiation produced by the isotopes that can escape from the lamp is negligible.[5]. If power is removed and reapplied, the ballast will make a new series of startup attempts. 1000Bulbs.com is proud to offer our customers products that have earned the government's ENERGY STAR label. SON High Pressure Sodium. The highest wear occurs when the HID burner is ignited while still hot and before the metallic salts have recrystallized. High pressure sodium lights are used for illuminating large outdoor areas. Varieties of HID lamp include: This shift is slight at first and is more generally a sign of the lamps being "broken in" whilst still being in good overall working order, but towards the end of its life, the HID lamp is often perceived as only producing blue and violet light. Clear tubular outer bulb. While upgrading to LED provides a lot of benefits, high pressure sodium (HPS) lamps still provide some of the most efficient lighting available. However, there is exactly one other type of lighting that beats HPS in that category, and that is Light Emitting Diode (LED). Metal-halide and ceramic metal-halide lamps can be made to give off neutral white light useful for applications where normal color appearance is critical, such as TV and movie production, indoor or nighttime sports games, automotive headlamps, and aquarium lighting. As a lamp gets older, the voltage necessary to maintain the arc eventually rises to exceed the voltage provided by the electrical ballast. high pressure sodium lamp manufacturer/supplier, China high pressure sodium lamp manufacturer & factory list, find qualified Chinese high pressure sodium lamp manufacturers, suppliers, factories, exporters & wholesalers quickly on Made-in-China.com.

This radiation causes high ionization inside the lamp without being able to escape from the lamp. In fact, they're roughly as efficient as LEDs in terms of their light output for each watt of energy used. Ultra-high performance (UHP) HID lamps are used in LCD or DLP projection TV sets or projection displays as well. street signs and pedestrians) left in the shadows by standard halogen lighting. These lamps can be started at a relatively low voltage. What is a High Pressure Sodium Light? These isotopes produce ionizing radiation of alpha and beta type. Suggestions < Back to product family. [citation needed]. Various types of chemistry are used in the arc tubes of HID lamps, depending on the desired characteristics of light intensity, correlated color temperature, color rendering index (CRI), energy efficiency, and lifespan. High-intensity discharge lamps (HID lamps) are a type of electrical gas-discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. The noble gas enables the arc's initial strike.
