4. HID 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.

5. Pulse Start Arc Tube One 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 Halide Starting Electrode Pulse Start Metal Halide

6. Quartz 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.

7. High 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.

8. HID Lumen Maintenance • With 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.

9. HID Colors HID 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.

10. HID 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.

11. HID Starting High Pressure Sodium • External Ignitor Required Pulse Start Metal Halide • External Ignitor Required Metal Halide • Internal Electrode: No external ignitor required Some 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.

12. HID End-of-Life Unlike fluorescent lamps, HID lamps “fail” differently than just extinguishing. They also vary in end-of-life between lamp types. • High Pressure Sodium • Arc voltage rises to a point where ballast cannot sustain it and the lamp repeatedly cycles on and off. • Metal Halide • Similar to mercury, long lamp life but lumen depreciation (reduced light output) dictates usable life.

13. HID Lamp ANSI Matrix Ballast 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.

14. Magnetic Ballast Circuit Types • Reactor (Rx) 2. High Reactance (Lag) 3. Constant Wattage Autotransformer (CWA)

15. 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). Advantages • Single Coil • Small Size • Good Efficiency • Lowest Cost Disadvantages • Poor Power Factor • Poor Regulation • Dip Tolerance 25% • Single Voltage • Available for Low Wattage MH & HPS 35-150 W

16. High 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. Advantages • Can be used with any input voltage Disadvantages • Heavier, larger, and more expensive than reactor type • Higher losses than reactors Notes • Used for multi-tap, low wattage HID lamps • Performance the same as a reactor • Also called HxNPF & HxHpf • Capacitor required for High Power Factor

17. Constant 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. Advantages • Better power line regulation • High power factor • Better voltage dip tolerance Disadvantages • Higher cost • Weight • Not as efficient as reactors or electronic HID Notes • Most common ballast on wattages above 150W.

18. Magnetic Ballast Construction Types • Core and Coil • Most common type of HID ballast • Constructed with one or two coils and steel laminations • Available for CWA, High Reactance, and Reactors • A wide variety of input voltages are available • Ballast is installed in an enclosed fixture housing • Capacitor and starter supplied (If needed) • Encased and Potted • Primarily 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

19. Ballast Factor Unlike 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.

20. Temperature 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 rise • Temperature codes are primarily used by the fixture manufacturers during their approval processes. • Replacement products are designed for operation in most applications.

21. Capacitors The 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.

22. Ignitors Many 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 Ignitor • Always comes with the ballast if the lamp requires an ignitor. • Auto Shutoff Ignitor • Excellent 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 Distance • For 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 Restrike • For low wattage HPS applications when the need for instant re-strike is required.

23. Voltages Unlike 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 voltages • Quad Tap: 120/208/240/277V • 480V w/ 120V tap for standby lighting • Canadian HID lighting voltages include 120, 277, and 347 volts. • Tri-Tap voltages meet these requirements: 120/277/347V
