  2. Twinkle bulb - Wikipedia

    en.wikipedia.org/wiki/Twinkle_bulb

    The advent of miniature lights found the adaptation of twinkle bulbs as flasher bulbs, which interrupt the entire series circuit of anywhere from 10 to 50 bulbs when powered from 120-volt mains electricity (in North America). These are easily recognizable by their red tips on an otherwise unpainted clear white bulb, and are available in the ...

  3. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    If the light bulbs are connected in parallel, the currents through the light bulbs combine to form the current in the battery, while the voltage drop is 12 volts across each bulb and they all glow. In a series circuit, every device must function for the circuit to be complete. If one bulb burns out in a series circuit, the entire circuit is broken.

  4. Holiday lighting technology - Wikipedia

    en.wikipedia.org/wiki/Holiday_lighting_technology

    Screw-base C7 and C9 light sets use line voltage (120 volt) bulbs and are wired in parallel. LED-based sets use a current-limiting resistor to reduce the current supplied to each LED. Neon-lamp-based sets have lamps connected in parallel, each with its own current-limiting resistor. Battery-powered sets are also wired in parallel. [citation needed]

  5. Crookes radiometer - Wikipedia

    en.wikipedia.org/wiki/Crookes_radiometer

    If light pressure were the cause of the rotation, then the better the vacuum in the bulb, the less air resistance to movement, and the faster the vanes should spin. In 1901, with a better vacuum pump, Pyotr Lebedev showed that in fact, the radiometer only works when there is low-pressure gas in the bulb, and the vanes stay motionless in a hard ...

  6. Chase (lighting) - Wikipedia

    en.wikipedia.org/wiki/Chase_(lighting)

    A chase is an electrical application where strings of adjacent light bulbs cycle on and off frequently to give the illusion of lights moving along the string. With computerized lighting consoles, building chase sequences has become easier, while previously chases used mechanical means, such as a wheel with an electrified spindle which strikes electrical contacts for each circuit.

  7. Christmas lights - Wikipedia

    en.wikipedia.org/wiki/Christmas_lights

    In the 1950s and 1960s, the series circuit connected light sets would go completely dark when a single bulb failed. So in the fairly recent past, the mini-lights have come with shunts to allow a set to continue to operate with a burned out bulb. However, if there are multiple bulb failures or a shunt is bad, the string can still fail.

  8. LED circuit - Wikipedia

    en.wikipedia.org/wiki/LED_circuit

    Parallel operation is also possible but can be more problematic. Parallel LEDs must have closely matched in order to have similar branch currents and, therefore, similar light output. Variations in the manufacturing process can make it difficult to obtain satisfactory operation when connecting some types of LEDs in parallel. [4]

  9. Incandescent light bulb - Wikipedia

    en.wikipedia.org/wiki/Incandescent_light_bulb

    An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires ...
