Ballast Technology
   Ballast Technology       
   Your choices are...         
   Electronic Ballast       Electronics ballasts convert 60-cycle power to drive lamps with high-frequency current of 20,000 hertz or more. By using high frequency current, this ballast takes advantage of fluorescent lamp efficiencies at these high frequencies. To accomplish this operation, the ballast uses electronics circuitry that results in a more efficient, smaller and lighter ballast design than the magnetic ballasts. 
   HID Ballast       High intensity discharge ballasts are used to start high intensity discharge (HID) lamps such as mercury vapor lamps, metal halide lamps, and high pressure sodium lamps. 
   Hybrid Ballast       Hybrid ballast combine the starting and operating characteristics of the magnetic ballast with the energy efficiencies of electronic ballasts to provide an alternative means of operating rapid start lamps. 
   Magnetic Ballast       Magnetic ballasts provide output power to lamps at line frequency (60 Hz, or 50 Hz). As a result of their design, these ballasts are also called "core and coil" ballasts.  These ballasts consist of a core of stacked steel laminations wounded by insulated copper or aluminum coils.  This arrangement functions both as a voltage transformer and a current limiting choke. To improve their power factor, some of these ballasts have a capacitor. Ballast with a capacitor is considered a high power factor or power factor corrected ballast.

   Start Method:       
   Your choices are...         
   Instant Start       Instant start ballasts start lamps by applying a high voltage with no preheating of the lamp filaments. Instant start ballasts require a larger amount of energy during the starting process, but use less energy during normal operation. 
   Programmed / Preheat       Preheat or programmed start is a method of starting fluorescent lamps in which the electrodes are heated before a switch opens to allow a starting voltage to be applied across the lamp. With preheat starting, the lamp flashes on and off for a few seconds before staying lit, because several starting attempts may be necessary to establish the electric arc across the lamp electrodes. 
   Rapid Start       Rapid start is a circuit designed to start fluorescent lamps by continuously heating or preheating the electrodes. Rapid start ballast start a lamp by first heating the cathode and then maintaining a constant arc across the cathode to provide the necessary heat for the operation. 
   Other       Other, not listed, start method such as trigger start methods.

Performance Specifications
   Ballast Factor       Ballast factor is the measurement of ballast’s ability to produce light from fluorescent lamps. It is the ratio of light output produced by lamps operating on a commercial ballast versus the light output of the same lamps operating on a laboratory reference ballast specified to ANSI standards for a given lamp type 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Total Harmonic Distortion (THD)       Harmonic distortion is a measure of the degree to which a sinusoidal signal is distorted by harmonic waveforms (multiples of the fundamental frequency). Total harmonic distortion (THD) is the combined effect of harmonic distortion on the AC waveform produced by the ballast or other devices. TDH is defined as the ratio of the magnitude of the input current harmonics to the amplitude of the fundamental current. In general, this is expressed in percentage. A high value of THD indicates high distortion. Electrical devices, such as computers and fluorescent lighting systems, can send harmonic wave forms at many frequencies back onto the power supply line, thereby distorting the current wave shape. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
