    High Pressure Sodium 400 watt grow light system includes a top quality HPS ballasts, super efficient reflector hood, and high performance lamp / grow light bulb.The brightest grow lights are high-intensity discharge (HID) lights. They can be installed anywhere in your home, garage, or greenhouse to supplement existing light, and they can serve as the sole source of light for your plants. 400W High Pressure Sodium (HPS) Bulb Specifications: Power: 400 watts (High efficiency) Rated Life: 24,000 hours Lumens: 50,000 lumens Color Temperature: 2,100K Strong power to penetrate fog High output, high luminescence efficiency. Fits all standard 400 watts HPS grow light systems These bulbs pass electricity through a glass or ceramic tube containing a mixture of gases. The blend of gases determines the color of the light given off by each type of lamp. HID lights are twice as efficient as fluorescent lamps; one 400-watt HID lamp emits as much light as 800 watts of fluorescent tubing.400 Watt High Pressure Sodium ballast for safety and is manufactured by James Lighting, a leading manufacturer of horticultural lighting fixtures and bulbs. The ballast is housed in a remote, steel ballast enclosure and features an innovative "thermal chimney". The "thermal chimney" actually separates the box into two sections - one for the ballast and the other for the components - igniter and capacitor. The "thermal chimney" keeps the components cooler by not allowing heat from the ballast to reach them. It is a thermal protective barrier between the magnetic choke and the components. The result is a cooler running unit with longer component and ballast lifespan. This ballast and housing are built to last. The innovative "thermal chimney" allows for effective cooling without the use of air vents and open ports inherent in other systems that allow for dirt, dust and water to contaminate the ballast system.

Select a basic high pressure sodium lighting system or upgrade the bulbs – there are many options for all your growing needs. Both metal halide (MH) lamps and high pressure sodium (HPS) lamps emit most of their light in spectrums which the plants use very inefficiently, yellow and green. Overall, HPS lamps emit more red and blue light, the spectrums that the plants use most efficiently to fuel photosynthesis. Part of the reason for this is that HPS lamps emit 10-20% more total light. Vegetative plants grown under 1000 watt HPS lamps grow faster than those under 1000 watt MH lamps. There is absolutely no reason to use MH lamps either in flowering or vegetative growth stages. MH lamps are useful for displaying plants. If you set up alternating rows of MH and HPS lamps you would notice a wave pattern, with more growth under the HPS lamps. Don't let grower myths or garden shop sales pitches convince you to buy unneeded equipment. Your best light source is a 1000 watt HPS lamp....

    High-pressure sodium (HPS) to metal halide (MH) street lamp installations based on their perceived brightness, safety, support of social interaction, and ability to support facial recognition and eyewitness identification. HPS lamps are the most commonly used lamps for outdoor applications due to their low initial and operating costs; more recently, however, MH lamps are also being used because they are comparable in cost to HPS lamps and are perceived as more inviting. However, some aspects of lighting “quality” cannot be objectively measured. A primary objective of outdoor street lighting is to improve security by supporting visibility of facial features. This underscores the importance of light level and light source color rendering in creating a sense of safety in outdoor environments. However, research has not considered these factors. High pressure sodium lighting may be more efficient and needs to be replaced less often. People who are concerned about the environment may choose either type of lighting. However, HPS ballasts tend to last longer. This means more convenience for you because of less frequent replacement. It also means better news for the earth since it takes longer for these lamps to end up in landfills. HPS lamps are available in color-corrected versions that shorten their life and only slightly improve color temperature. Even with greatly improved CRIs, the color temperature still delivers yellow light. This color limitation is present because the HPS lamp generates light through the excitation of sodium. Metal halide lamps, on the other hand, generate light through the excitation of 2 to 5 different chemicals in the arc tube. In addition, the exclusive Uni-Form formed body arc tube is a newly-designed, compact light source sculpted to follow the physical shape of the arc itself. The precise geometry of this unique arc tube, accurately reproducible from lamp to lamp, produces a metal halide lamp of greater efficiency, improved color uniformity, and longer life. HPS is sometimes preferred for outdoor lighting. The reason for this is that night vision tends to be affected more by the metal halide lighting than by the HPS lighting. If you have a group of people outside under lighting who also need to see things that are going on outside of the lit area then you might want HPS lighting....

    Both high pressure sodium and metal halide lamps are considered HID (high intensity discharge). These bulbs, which are mostly used in outdoor settings, offer different amounts of light output and operate in different color spectrums. MH produces more sky glow, lumen for lumen, than HPS for the same quantity of radiant energy from each source, due to higher blue light component and the Rayleigh scatter effect. MH lamps contain significantly more mercury than HPS lamps. For example, a 250W MH lamp contains about 38 mg of mercury vs. about 15 mg for an HPS lamp of the same wattage. Mercury is a potent neuro-toxin that persists indefinitely in the environment.Whenever MH is within close proximity to housing units, MH lighting will only increase the health risk. MH lamps are great for growing plants indoors. Since these lamps are more like natural sunlight, they are the best option for people who want to be able to grow plants indoors in the area that they are lighting up. This is particularly true if you are trying to grow vegetative plants as opposed to flowering plants. Metal halide lamps, a member of the high-intensity discharge (HID) family of lamps, produce high light output for their size, making them a compact, powerful, and efficient light source. By adding rare earth metal salts to the mercury vapor lamp, improved luminous efficacy and light color is obtained. Originally created in the late 1960s for industrial use, metal halide lamps are now available in numerous sizes and configurations for commercial and residential applications. Like most HID lamps, metal halide lamps operate under high pressure and temperature, and require special fixtures as well as ballast to operate safely. Since the lamp is small compared to a fluorescent lamp or incandescent lamp of the same light level, relatively small reflective luminaires can be used to direct the light for different applications (flood lighting outdoors, or lighting for warehouses or industrial buildings)....

    A single coil choke can be used when the input voltage to a fixture meets the starting and operating voltage requirements of an HID lamp. In this situation, the reactor choke performs only the current-limiting functions since the voltage necessary to initiate the ignitor pulses, and start and sustain the lamp comes directly from the input voltage to the fixture. The reactor choke is electrically in series with the lamp. There is no capacitor involved with the operation of the lamp. Because of that, the lamp current crest factor is desirably low, in the 1.4 to 1.5 range. Metal halide lamps use sodium in their arc tubes to give them comparatively high light output. The arc tubes also have other metals or chemicals mixed with the sodium to balance and improve color. In fact, these lamps have become the standard for lighting sports for TV. Their lives are shorter than those of mercury lamps;but, they are significantly more efficient.High pressure sodium (HPS) lamps generate light with a sodium (primarily) arc discharge. This gives them the highest luminous efficacy (lumens of light per watt of energy used) of these three lamps (over twice that of mercury). Their average rated life is similar to that of mercury lamps. All three HID lamps require supplemental electromagnetic and/or electronic circuitry (normally called a “ballast”) to start and stabilize the arc discharge and to condition the external power supply to the lamp's specific electrical requirements. The selection of a ballast type depends on where it is to be used. Mercury and metal halide lamps change little in operating characteristics over life and ballast operation remains fairly constant. But HPS lamps change operating characteristics dynamically over life. Following is an explanation of general operating characteristics of HPS ballasts followed by a tabular listing of typical electrical data of different ballast wattages and types for all three HID lamps. Without a ballast capacitor, the reactor chokes are inherently normal power factor devices (50%). Where necessary, to reduce the current draw during lamp operation, a capacitor may be utilized across the input line to provide high power factor (90%) operation, but the addition of the capacitor will not affect how the choke operates the lamp. Reactor chokes limit the number of fixtures that can be used on a circuit because they draw substantially more current during lamp starting (warm-up) and/or open-circuit operation (burned-out or missing lamp), than when the lamp is operating normally....

    All fluorescent light fixtures consist of at least lamp(s), lamp holders, fluorescent ballast and internal wiring. Some older types have "starters", too. The ballast is used to create the voltage and current necessary to start and illuminate the fluorescent lamp A starter for a fluorescent light is located on the fixture and is a round cylinder that is about 1 1/2 inches in length. The starter sends an electrical charge to the bulb which helps it light. Fluorescent starters are used in several types of fluorescent lights. The starter is there to help the lamp light. When voltage is applied to the fluorescent lamp, here's what happens: The starter (which is simply a timed switch) allows current to flow through the filaments at the ends of the tube. The current causes the starter's contacts to heat up and open, thus interrupting the flow of current. The tube lights. Since the lighted fluorescent tube has a low resistance, the ballast now serves as a current limiter. When you turn on a fluorescent tube, the starter is a closed switch. The filaments at the ends of the tube are heated by electricity, and they create a cloud of electrons inside the tube. The fluorescent starter is a time-delay switch that opens after a second or two. When it opens, the voltage across the tube allows a stream of electrons to flow across the tube and ionize the mercury vapor. Without the fluorescent ballast starter, a steady stream of electrons is never created between the two filaments, and the lamp flickers. Without the ballast, the arc is a short circuit between the filaments, and this short circuit contains a lot of current. The current either vaporizes the filaments or causes the bulb to explode....

    The core and coil ballasts method creates a huge amount of inductive reactive power, significantly exceeding the magnitude of active power, but this reactive power can easily and cheaply be compensated without risk of any interferences, if done adequately (see section 5). The electronic ballast does not – or should not – produce substantial amounts of fundamental reactive power (displacement power factor DPF or cosφ). It need not but may be designed to operate on different mains frequencies, including DC, and different voltages, thereby also compensating any input voltage variances. The decisive argument put forward for its use is, however, the energy saving achieved, not so much by lower internal losses in the ballast itself, but rather by an efficiency improvement of the lamp when operated at the high frequency supplied from the output terminals of such electronic ballast. For this reason they feed less power into the lamp than a magnetic ballast does. However, electronic ballasts are several times more expensive than the plain passive magnetic models and much more susceptible to certain disturbances and are likely to become themselves a source of disturbances. core and coil ballasts limit the flow of current to the light but do not change the frequency of the input power. The lamp then illuminates on each half-cycle of the power source. This is why many fluorescent and neon lights visibly flicker. Since the light illuminates on half-cycles, the rate of flicker is twice the frequency of the power source, meaning the light will flicker at 100Hz or 120Hz. A lead-lag lighting ballast can minimize flicker when connected to two lamps by alternating the flow of current to them: one leading the frequency of the input power and the other lagging behind it. A more modern type of lighting ballast is electronic instead of electromagnetic. An electronic lighting ballast uses solid state circuitry to transform voltage, but unlike electrocore and coil ballasts, can also alter the frequency of power. This means that an electronic lighting ballast can greatly reduce or eliminate any flicker in the lamps. Because it uses solid-state circuitry instead of magnetic coils, it is also more efficient and therefore runs cooler. Because of their greater efficiency and ability to reduce flicker, electronic ballasts are more popular than electrocore and coil ballasts, and are often used to replace them. A few applications, however, require an electromagnetic lighting ballast, such as ballasts that must preheat or ballasts for extremely high output lamps....

    High Intensity Discharge (HID) lamps require a magnetic choke to apply starting voltage to the lamp and establish current flow – an arc – between the lamp electrodes. Without a ballast, the arc will extinguish or draw increasing current until some circfering of major brand Medium and Mogul Base HPS Lamps. Metal halide lamps are one of three types of high intensity discharge (HID) lamps in general use. The other two types are mercury and high-pressure sodium lamps. HID lamps have bright light output making them perfect for outdoor lighting. HID ballasts perform the following functions: • Provide voltage to breakdown the gas between the electrodes of arc lamps and initiate starting. • Provide voltage and current to heat the electrodes to allow a low voltage, high current arc mode to develop (referred to as glow-to-arc transition, GAT). • Provide enough current to heat and evaporate the light emitting components after an arc has been established. Provide enough sustaining voltage to maintain the arc during warm-up and operation. • Set lamp current once all the evaporable materials have reached thermal equilibrium. Magnetic choke kits are used in over 90% of all HID lighting. Replacement high pressure sodium HPS ballasts kits contain the appropriate core and coil, a properly rated ignitor and all components required for ballast replacement. The James lighting, core and coil, HID ballast kit is ideal for a wide variety of lighting applications, including factories, warehouses, gymnasiums and retail stores.uit element burns up. Ballasts provide system stability by limiting the current that can be drawn....

    Magnetic choke is a type of fluorescent light that regulates the voltage of a fluorescent lamp by using a magnetic core. It works by using an electrical load to limit the flow of current especially when the load presents negative resistance.Magnetic choke can also be used to reduce the current in an ordinary positive circuit. A Magnetic choke work by power supply, once the ignitor makes a plasma response in the gases in the fluorescent tube, the ballast purchases power that allows the plasma reaction to continue.Magnetic chokes were the first type of ballast and regularly have very low cycle charges that can effect in subtle flaming in the light. fluorescent lamp ballast means a device which is used to start and operate fluorescent lamps by providing a starting voltage and current and by limiting the current during normal operation. The fluorescent lamp ballasts that are subject energy conservation standards include ballasts that operate. Definitions for several of the covered ballast types are specified in the Code of Federal Regulations at 10 CFR 430.2. Fluorescent lamp ballasts that are designed to operate at nominal input voltages of 120 or 277 volts; to operate with an input current frequency of 60 Hertz James's ballast products represent many years of experience in ballast design and manufacturing. James offers magnetic chokes for all HID lighting sources including standard and pulse start metal halide lamps and high pressure sodium (HPS) lamps....

    Magnetic chokes use magnetic components to start and regulate the operation of a lamp. Inductors are used as the current limiting component in EM ballasts. Although the inductor is very good at regulating current, it causes a phase shift input of the current waveform creating a nonideal power factor. Often times a Capacitor is used in Magnetic chokes to correct the power factor. A few of the most common Magnetic chokes are shown below. A Magnetic chokes is a part used in electrical circuits to allow DC current to flow through while blocking AC current from passing. These coils are used in a number of electrical devices. When used as part of a radio’s circuitry, it falls into one of two frequency classes: audio or radio. Those used in circuits with higher frequencies use different core materials than those used in lower frequency circuits. During the process of sending a signal through a circuit, the idea is to let the desired signal go through while filtering out other, unwanted signals. One type of unwanted signal is common-mode noise, which is filtered out by a common-mode Magnetic chokes. Power lines are an example of a source of common-mode noise. Without a coil, the power line would create a lot of electrical noise as it traveled to its destination, which would then be received on the other end and possibly cause interference with the signal. The HPS ballasts works because it acts as an inductor. When the current passing through changes, as AC currents do, it typically creates a magnetic field in the coil that works against that current. This property, known as inductance, blocks most of the AC current from passing through. As a result, currents that do not change, such as DC currents, can continue through while those that do are blocked by the very magnetic field they created....
