   The energy-saving T12 lamps are made to operate on ballasts designed for 40-watt F40T12 lamps, though some F40T12 ballasts are not be designed to operate these lamps, and can overheat if energy-saving lamps are used. Running an energy-saving T8 tube with a ballast for T12 will reduce lamp life and can increase energy consumption. [9]

3. Fluorescent lamp - Wikipedia

   en.wikipedia.org/wiki/Fluorescent_lamp

   The spectrum of light emitted from a fluorescent lamp is the combination of light directly emitted by the mercury vapor, and light emitted by the phosphorescent coating. The spectral lines from the mercury emission and the phosphorescence effect give a combined spectral distribution of light that is different from those produced by incandescent ...

4. Electrical ballast - Wikipedia

   en.wikipedia.org/wiki/Electrical_ballast

   Ballasts for sign lighting in the United States, are heavier duty than other ballasts because the cooler outdoor temperatures increase the energy required to start a fluorescent tube. They are sized based on the total tube length used. Typical European 230V series choke ballast 40W T12 or 36W T8 fluorescent lamps.

5. Tanning lamp - Wikipedia

   This allows a 100 watt lamp to fully light with as little as 65 watts. S12 lamp starter. The disadvantage of the newer electronics is price. It can cost 3 to 5 times more per lamp to use electronic ballasts than traditional choke ballasts, which is why choke ballasts are still used in the majority of new tanning systems.

6. Energy saving lamp - Wikipedia

   en.wikipedia.org/wiki/Energy_saving_lamp

   Energy saving lamps are sources of artificial light that employ advanced technology to reduce the amount of electricity used to generate light, relative to traditional filament-burning light bulbs. Examples of energy saving lamps include: Fluorescent lamps; i.e. regular and compact; LED lamp; a Light-emitting electrochemical cell; Magnetic ...

7. Glow switch starter - Wikipedia

   en.wikipedia.org/wiki/Glow_switch_starter

   A preheat fluorescent lamp circuit using automatic starting switch. A: Fluorescent tube, B: Power (+220 volts), C: Starter, D: Switch (bi-metallic thermostat), E: Capacitor, F: Filaments, G: Ballast. When power is first applied to the circuit, there will be a glow discharge across the electrodes in the starter lamp.
