More current required for the same power Power Factor Power factor indicates how efficiently the power from the utility is being utilized. The higher the power factor, the less current is needed to provide the same amount of power. A high power factor ballast allows for more ballasts on a circuit. Also, utilities have penalties for facilities with low power factors since it requires more current to be generated. The formal equation: PF = Actual Power (Watts)/Apparent Power (Volts x Amps) Example: 120 Watts of lighting @ 120V with PF=.99 Input Current = 1 amp 120 Watts of lighting @ 120V with PF=.60 Input Current = 1.66 amps More current required for the same power The power factor indicates how efficiently the power from the utility is being utilized. The higher the power factor, the less current is needed to provide the same amount of power. A high power factor ballast allows for more ballasts on a circuit. The equation to determine the power factor of a ballast is Actual Power (Watts)/Apparent Power (Volts X Amps). A power factor equal to or above .90 is considered High Power Factor

Total Harmonic Distortions (THD) THD is a measurement of the harmonic content in the current a piece of equipment draws from the power line. THD is percentage value. High Harmonic Values can: Result in Large Neutral Currents in 3-phase Systems Potential for overheating neutral conductors Cause Voltage distortion problems THD or Total Harmonic Distortion is a measurement of the harmonic content in the current a piece of equipment draws from the power line. THD is percentage value. High harmonic values can result in large neutral currents in 3-phase systems and can also cause voltage distortion problems. The distorted line represents a current wave shape with 17% THD versus a pure sinusoid wave shape with no THD

System Retrofit Analysis with effect on THD Lighting System Before a Retrofit 2 lamp magnetic ballast with F34T12 lamps Ballast THD = 20%, Watts = 74W, I = .65A Harmonic Current  .20 x .65 = .13A New Electronic Lighting System after Retrofit 2 lamp Electronic “L” ballast with F32T8 lamps THD = 20%, Watts = 51W, I = .44A Harmonic Current  .20 x .44 = .088A Here you can see an example of a system retrofit analysis with effect on THD. This particular example shows a 32% reduction in harmonic current and in power consumption. This Retrofit with an Electronic Ballast Provides approximately a 32% Reduction in Harmonic Current and in Power consumption

THD: Typical Values Electro Magnetic Ballasts: Less than 30% ANSI Commercial Ballast Requirement: Less than 32% Universal’s HP Family: Less than 10% Typical screw-in CFL’s: Greater than 100% Typical specified THD levels are either less than 10% or less than 20%. Requirements for ballasts to meet ANSI requirements allows for THD values to be just less than 32%. In the example on this slide, you can compare Universal’s THD levels to typical product families around the industry. Typical specified THD Levels are either less than 10% or less than 20%. Requirements for ballasts to meet ANSI requirements allows for THD values to be just less than 32%.

Starting Temperatures Minimum starting temperature is both ballast and lamp dependent See ballast label for specifics (std. is 50⁰F (10⁰C) for most magnetic ballasts) Energy saving lamps do not function well below 60⁰F (16⁰C), including the newer 25, 28, and 30-Watt T8 lamps Many electronic ballasts are designed for 0⁰F (-18⁰C) or -20⁰F (-29⁰C) starting Magnetic High Output: -20⁰F (29⁰C) In low temperature applications, it is important for the lamps to heat up to generate sufficient light output. Lamp Jackets are typically used in these applications so that the heat that the lamp generates is used to heat the lamp rather than to dissipate into the outside air. Minimum starting temperature is both ballast and lamp dependent. You can see specifics on the label of a ballast. Energy saving lamps do not function well below 60 degrees Fahrenheit. Many electronic ballasts are designed for 0 degree Fahrenheit starting temperature. In low temperature applications, it is important for the lamps to heat up to generate sufficient light output.

Remote Mounting Remote Mounting Distance Definition: Maximum allowable length of the ballast lead wire from the ballast to the lamp socket. Typical remote mounting distances: Instant Start: 18’ with full wattage lamps Programmed Start lamp: 20’ with full wattage lamps Instant Start & Programmed Start: 6’ with ES lamps Consult specification sheets for specific ballasts The definition of remote mounting distance is the maximum allowable length of the ballast lead wire from the ballast to the lamp socket. Here you can see the typical remote mounting distances of different product types. Ballasts are limited in how far they can be mounted from the lamps they are operating. For electromagnetic ballasts, larger gauge wire is necessary to compensate for voltage drops from the leads. For electronic ballasts, high frequency interactions between the leads and conduit reduce the ballast output voltage. For electronic ballasts, a maximum distance is specified by the ballast manufacturer. Ballasts are limited in how far they can be mounted from the lamps they are operating. For electromagnetic ballasts, larger gauge wire is necessary to compensate for longer distances as voltage drops from the leads. For Electronic ballasts, high frequency interactions between the leads and conduit reduce the ballast output voltage. For electronic ballasts, a maximum distance is specified by the ballast manufacturer.

Shut Down Circuits - End of Lamp Life (EOL) When lamps with a bulb diameter of T5 or less are operated on high frequency electronic ballasts without EOL sensing circuitry, one or both of the following scenarios may occur at end-of-lamp-life: 1. Glass cracking near lamp base (The filament opens and touches the glass) 2. Overheating or melting of lamp base or socket (Lamp rectifies at the end of life and generates significant heat at the filaments and socket) Many ballasts now include shutdown circuits that sense when the lamp is at its end of life and will shut down power to the lamps to prevent the undesirable failure modes When lamps with a bulb diameter of T5 or less are operated on high frequency electronic ballasts without EOL sensing circuitry, one or both of the following scenarios may occur at end-of-lamp-life: 1) glass cracking near lamp base (filament opens and touches the glass) and 2) overheating or melting of lamp base or socket (Lamp rectifies at the end of life and generates significant heat at the filaments and socket). Many ballasts now include shutdown circuits that sense when the lamp is at its end of life and will shut down power to the lamps to prevent the undesirable failure modes.

UL Listed Underwriters Laboratory UL 935: Fluorescent-Lamp Ballasts Standard Safety Requirement Assure proper ratings on labels Lamps Approved Maximum Input current ratings Input & Output Voltages Requires passing of various tests for safe operation, including…. Faults are induced within the ballast to confirm that the ballast fails safely Tests for shock hazard potential during lamp replacements Confirms case temperatures are within limits Requires 100% production tests for insulation/isolation from internal components and lead wires This slide shows how a ballast is properly UL Listed. UL935 is the ballast standard. For safety requirements, one has to ensure that the proper ratings on labels which would have to include the following: lamps that are approved for use, input current ratings, and input/output voltages. These ballasts also require passing of various tests for safe operation: faults are induced within the ballast to confirm that the ballast fails safely, tests for shock hazard potential, and confirmation of case temperatures. It also requires 100% production tests for insulation/isolation from internal components and lead wires.

New DOE Ruling for 2014 (BLE) The Energy Policy & Conservation Act (EPCA) was signed into law on November 14, 2011. As part of this larger Ballast Rule, a new linear fluorescent efficiency standard became law on January 13, 2012. The new efficiency measurement standard for manufacturers is called BLE (Ballast Luminous Efficiency) and replaces the older Ballast Efficacy Factor (BEF) metric. This law comes into enforcement on November 14, 2014. This grace period allows manufacturers to make the necessary changes in design to meet the new efficiency standards. After this date, the government will prohibit the domestic manufacture and importation of products that don’t meet the new standards. This will not affect the sale of any completed units in inventory. Existing inventories can be sold until they are consumed. This new DOE 2014 Ballast Rule requires higher efficiency in many of today’s linear fluorescent ballasts. It will affect nearly all non-dimming ballasts for linear lamps in the 120 – 277 volt range.   The Energy Policy & Conservation Act (EPCA) was signed into law on November 14, 2011.

Legislation Shift to Efficiency New efficiency requirements will continue to drive the market to higher efficiency T5, T8, dimming, demand response, and LED solutions. New efficiency requirements will continue to drive the market to higher efficiency T5, T8, dimming, demand response, and LED solutions. Some may ask why did DOE change the efficiency metric? The metric, since 1984, has been Ballast Efficacy Factor (BEF). In 2011, the Ballast Luminous Efficiency (BLE) metric was created. Unlike BEF, BLE is based solely on electrical measurements and removes variability by measuring true power in and true power out of the ballast. BLE shows the losses inside the ballast only. What are the advantages of using BLE? 1) Clear view of ballast performance – lamp is only a load, 2) No photometrics are needed – only electrical measurements, 3) No reliance on lamp efficacy, 4) Measurement is repeatable and reliable, minimizes error due to photometrics, 5) More accurate measurement of ballast efficiency, and 6) Ballast is measured warm, as actual operation use condition, giving true picture of steady state performance.

Retrofit Energy Savings Electronic ballasts are commonly used in lighting retrofits where magnetic ballasts with T12 lamps are removed from lighting fixtures and replaced with electronic ballasts and T8 lamps. The key reason for this is the significant financial savings that result from these energy saving retrofits although there are numerous other lighting benefits that are achieved. To Calculate the financial savings, the following information is needed: Existing lighting fixture’s input power Replacement system’s input power Annual hours of operation Utility rate Quantity of lighting fixtures Electronic ballasts are commonly used in lighting retrofits where magnetic ballasts with T12 lamps are removed from lighting fixtures and replaced with electronic ballasts and T8 lamps. The key reason for this is the significant financial savings that result from these energy saving retrofits although there are numerous other lighting benefits that are achieved. To calculate the financial savings, the following information is needed: existing lighting fixture’s input power, replacement system’s input power, annual hours of operation, utility rate, and quantity of lighting fixtures. Input power values are available from ballast manufacturers’ catalogs or specification sheets. Input power values are available from ballast manufactures catalogs or specification sheets

Retrofit Energy Savings Equations Energy Savings = Existing Wattage – New Wattage Annual Utility Savings per Fixture: Energy Savings (Watts) x Annual Operating Hours x Utility rate ($/kWH)  1000 (for conversion of units) Annual Utility savings ( $’s) The equation for energy savings equals existing wattage minus new wattage. The formula is showing in the example in this slide.
