Normal Power Factor: Power factors that have not been corrected above 90%. Typically an uncorrected power factor is 40-60%.

UL: (Underwriters Laboratories Inc) Laboratory that sets safety standards for building materials, electrical appliances and other products.
Type CC: (Closed Cabinet) Ballasts rated for small enclosed areas.
Ballast Factor (Light Output): A measure of the light produced by a lamp operated by a ballast compared to the light produced by a laboratory standard lamp operated by a reference ballast. Expressed as a percentage.
BEF (Ballast Efficiency Factor): This is the ratio of ballast light output to the input power. Used to compare
different ballasts on a light output to power consumption basis. BEF = % light output / input power (watts)
Class B: An operating temperature classification for electrical components established by UL. Class B allows operation up to 130ºC.
Class H: An operating temperature classification for electrical components established by UL. Class H allows operation up to 180ºC.
Class P: The UL classification for thermally protected ballasts. Indoor fluorescent fixtures are required to have thermally protected ballasts. Internal thermal protector removes input power whenever specified temperature limits are exceeded, about 100-110ºC.
Instant Start: initial high voltage to break down the arc tube and initiate the flow of current. During the starting the cathode should establish the hot spot in 15 to 30 milliseconds. Usually identified by the single pin base. No preheating of the filament is required. Also a line of ballasts and lamps that utilize instant start usually T12 at 425mA, but also T8 and T6 at 300mA, 2’-8’ with single pin bases.
Magnetic Ballasts: A ballast that operates principally through the use of current carrying copper or aluminum coils assembled on a magnetic steel core, instead of electronic components, to operate lamps.
Rapid Start: A circuit where the electrode heating voltage and the starting voltage are applied to the lamp simultaneously through small, low-voltage filament windings. The open circuit voltage of the ballast is adequate to start the lamp only after the filaments have heated to emission temperature, and the lamps light when the electrodes have reached the proper temperature. The electrode heat remains on all the time the lamps are burning (continuous cathode heat). Also a family of lamps and ballasts that utilize continuous electrode heat. The family may contain the F40 line, which runs at 430mA, the HO line, which runs at 800mA, and the PG/VHO/SHO line, which runs at 1500mA.
PreHeat: A circuit where the lamp electrodes are heated by a switch, glow bottle starter, or electronic circuit prior to operating the lamp. When the filaments have heated up, the starter opens and the ballast then provides a suitable voltage to light the lamp and limits the current flow to the proper value. Several seconds are required to complete the starting
operation. Preheat lamps must use preheat ballasts.
Trigger Start: A variation of the preheat start circuit, the ballast operates preheat lamps in a rapid start manner by suppling continuous voltage to the electrodes to heat them to the proper temperature. Upon starting, the electrode voltage is reduced about one half to reduce the losses.
Thermal Protection: A device inside of the ballast, which senses the temperature and will disconnect the input power whenever the limit is exceeded. This usually consists of a bimetal switch. This protection guards against excessive temperatures, which may be caused by abnormal voltage. Thermal protection may be of two varieties, automatic resetting or nonresetting (like a fuse). When a nonresetting protector operates, the ballast may be permanently inoperable, and must be replaced. If the thermal protector meets certain UL specifications, the ballast can be classified as "Class P".
Total Harmonic Distortion: The combined effect of harmonic distortion on the AC waveform produced by a ballast or other device. Expressed as a percentage. Excessive levels of THD can create large currents on the neutral line of a four-wire Wye three-phase system.
Crest Factor: A function of the ballast, it is the ratio of the peak current value divided by the RMS current value. May be voltage or current crest factor. Usually high current crest factors result in reduced performance and ballast life.
Programmed Start: A programmed-start ballast is a more advanced version of rapid start. This ballast applies power to the filaments first, it allows the cathodes to preheat and then applies voltage to the lamps to strike an arc. This ballast gives the best life and most starts from lamps, and so is preferred for applications with very frequent power cycling such as vision examination rooms and restrooms with a motion detector switch.

Auto Rest Shutdown Circuit Circuit senses lamp end of life and will automatically shut off power to the lamp(s). When a new lamp is inserted in the socket, the ballast resets, and turns on the lamp automatically. Some shutdown circuits require the power to be interrupted before a new lamp will re-light.
End of Life (EOL) Detects lamps that are near theif End-of-Life. EOL circuits typically sense this condition by measuring the DC offset of the lamp voltage wave form that occurs as the lamp electrode decays. When the circuit determines that the lamp is nearing its end, the AC ballast will shut down rather than powering the lamp. This action is designed to prevent the lamp from overheating. Most EOL detection circuits also trip when a lamp is removed or missing.
VDE The VDE Mark indicates conformity with the VDE standards or European or internationally harmonized standards resp. and confirms compliance with protective requirements of the applicable EC Directive(s).
ENEC "European Norms Electrical Certification". This demonstrates that a product has been certified by one of the national certification institutes in Europe.
