4HID Lamps Three different types: Mercury (Banned by DOE) High Pressure Sodium (HPS):Ceramic arc tube is populated with mercury and sodium vapors under high pressure.High voltage applied across arc tube causes the vapors to generate an orange/yellow light.Metal Halide (MH) Family (Standard Metal Halide and Pulse Start Metal Halide):Arc tube is populated with mercury and metal halide salt gases under high pressure.High voltage applied across cathode causes the salt atoms to generate UV and visible light.Bulb wall filters out UV and allows visible light to pass through.
5Pulse Start Arc TubeOne of the key differences between the pulse start metal halide lamp and standard metal halide lamps is that the standard MH lamp has a starting electrode as part of the arc tube.Removal of this starting electrode improves the efficiency and lighting quality of the lamp.Because there is no starting electrode, pulse start lamps require the ballast to have an ignitor.Standard Metal HalideStarting ElectrodePulse Start Metal Halide
6Quartz and Ceramic Metal Halide Many metal halide lamp wattages are available with quartz or ceramic arc tubes.Quartz is the older technology that has typically been installed.Ceramic arc tubes provide better color rendering. (Whiter whites!)Ceramic lamps are available for pulse start lamps only.
7High Pressure Sodium Lamps High Pressure Sodium (HPS) lamps are the most efficient type of HID lamp but since their color is not very good, HPS lamps may not be ideal for some applications.Pulse Start MH lamps also provide very good efficiencies.
8HID Lumen MaintenanceWith Magnetic HID ballasts ...Over the life of an HID lamp, the light output drops off.HPS drops off the least, followed by Pulse Start MH.
9HPS and Mercury provide the lowest CRI. HID ColorsHID lamps vary in their ability to provide quality “white” lighting. The chart below identifies the lamp color and other attributes. The higher the CRI (color rendering index), the closer the lamp color is to having a full true white color spectrum.Ceramic MH provides the highest Color Rendering (CRI) available for HID lamps.HPS and Mercury provide the lowest CRI.
10HID Warm-Up & Re-Strike All HID lamps require time to warm up when initially turned on and have a re-strike delay time when they are inadvertently shut off during operation.
11HID Starting High Pressure Sodium External Ignitor RequiredPulse Start Metal HalideMetal HalideInternal Electrode: No external ignitor requiredSome HID lamps require an external ignitor to be used as part of the lighting circuit.When these are required, they are included with the ballast.
12HID End-of-Life High Pressure Sodium Metal Halide Unlike fluorescent lamps, HID lamps “fail” differently than just extinguishing. They also vary in end-of-life between lamp types.High Pressure SodiumArc voltage rises to a point where ballast cannot sustain it and the lamp repeatedly cycles on and off.Metal HalideSimilar to mercury, long lamp life but lumen depreciation (reduced light output) dictates usable life.
13HID Lamp ANSI MatrixBallast specifications identify the HID lamps that are to be used by their ANSI lamp designations.This is to prevent compatibility problems in identifying lamp types of the same wattage that require different ballast types.
15Available for Low Wattage MH & HPS 35-150 W Reactors (Rx)Reactor ballasts have a single coil and are designed for a single input voltage.They are connected with an ignitor to the lamp and can also have a capacitor for power factor correction.Reactor ballasts perform poorly when the power line fluctuates (poor regulation).AdvantagesSingle CoilSmall SizeGood EfficiencyLowest CostDisadvantagesPoor Power FactorPoor RegulationDip Tolerance 25%Single VoltageAvailable for Low Wattage MH & HPS W
16High Reactance (Lag)High Reactance ballasts have two coils and are available with multiple taps for different input voltages.They are low power factor but can have a capacitor for power factor correction.AdvantagesCan be used with any input voltageDisadvantagesHeavier, larger, and more expensive than reactor typeHigher losses than reactorsNotesUsed for multi-tap, low wattage HID lampsPerformance the same as a reactorAlso called HxNPF & HxHpfCapacitor required for High Power Factor
17Constant Wattage Autotransformer (CWA) CWA ballasts have two coils and are available with multiple taps for different input voltages. They are high power factor and provide good regulation with the power line.AdvantagesBetter power line regulationHigh power factorBetter voltage dip toleranceDisadvantagesHigher costWeightNot as efficient as reactors or electronic HIDNotesMost common ballast on wattages above 150W.
18Magnetic Ballast Construction Types Core and CoilMost common type of HID ballastConstructed with one or two coils and steel laminationsAvailable for CWA, High Reactance, and ReactorsA wide variety of input voltages are availableBallast is installed in an enclosed fixture housingCapacitor and starter supplied (If needed)Encased and PottedPrimarily used for indoor downlighting applications where quiet operation is essential.All of the components are enclosed in a fluorescent-style ballast can and are thermally protected.Available for most lamp types up to 400W
19Ballast FactorUnlike fluorescent ballasts, which are offered with a variety of ballast factors, HID ballasts have ballast factors of 1.00.Lumens from the lamp are identified by the lamp manufacturer.System lumens will take into account lamp lumens and fixture efficiencies.Ballasts are not part of the system lumen equation.Unique applications may have ballast factors less than 1.00, but these are not very common.
20Temperature Codes UL Bench Top Rise Ratings HID ballasts have temperature codes to identify the temperature rises at which they operate.The best rating is “A,” which represents the lowest temperature rise“J” rating has the highest temperature riseTemperature codes are primarily used by the fixture manufacturers during their approval processes.Replacement products are designed for operation in most applications.
21CapacitorsThe majority of HID ballasts use capacitors for lamp current control or power factor correction. These were once available only in metal cans, but many of them are now constructed with plastic housings and are referred to as “dry” capacitors.Capacitor Ratings:Capacitors are rated in microfarads and volts.Replacement capacitors must be the same microfarads and equal or higher volts than the capacitor being replaced.Why choose dry capacitors?They are smaller in size.The plastic case does not conduct electricity, nor does it require grounding.They can operate at higher temperatures, up to 105° C.
22IgnitorsMany HID lamps require that ignitors (a.k.a. starters) are connected to the lamps to provide an ignition pulse to start the lamp. When ignitors are required, they are shipped along with the ballast. There are different types of ignitors that will provide additional benefits.Standard IgnitorAlways comes with the ballast if the lamp requires an ignitor.Auto Shutoff IgnitorExcellent choice when the fixture is in a place that is difficult to maintain.The ignitor will stop pulsing after a predetermined time to minimize wear on the ballast and the ignitor.Long DistanceFor use when the ballast is remote-mounted from the lamp.Standard ignitors are limited from some applications by the distance that they can be mounted from the lamp.Instant RestrikeFor low wattage HPS applications when the need for instant re-strike is required.
23VoltagesUnlike magnetic fluorescent ballasts, many HID ballasts can operate on a variety of input voltages. These ballasts have separate voltage taps, and they require that the input voltage to be connected to the appropriate tap. This benefit allows contractors and distributors to stock fewer ballasts while meeting their requirements.U.S. HID lighting voltages include 120, 208, 240, 277, and 480 volts.Common ballast that meet these are:5-Tap: 120/208/240/277/480V – covers ALL voltagesQuad Tap: 120/208/240/277V480V w/ 120V tap for standby lightingCanadian HID lighting voltages include 120, 277, and 347 volts.Tri-Tap voltages meet these requirements: 120/277/347V
