3. A-series light bulb - Wikipedia

   en.wikipedia.org/wiki/A-series_light_bulb

   The most commonly used A-series light bulb type is an A60 bulb (or its inch-based equivalent, the A19 bulb), which is 60 mm (19 ⁄ 8 in or 2 + 3 ⁄ 8 in) wide at its widest point and approximately 110 mm (4 + 3 ⁄ 8 in) in length. Other sizes with a data sheet in IEC 60064 are A50, A55, A67, A68, A71, A75, and A80.

4. 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 ...

5. 3-way lamp - Wikipedia

   en.wikipedia.org/wiki/3-way_lamp

   A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. So unlike incandescent bulbs controlled by a ...

6. Centennial Light - Wikipedia

   en.wikipedia.org/wiki/Centennial_Light

   The Centennial Light is an incandescent light bulb, recognized as the oldest known continuously operating light bulb. It was first illuminated in 1901, and has only been turned off a few brief times since. It is located at 4550 East Avenue, Livermore, California, and is open to public viewing. [1] Due to its longevity, the bulb has been noted ...

7. Fluorescent-lamp formats - Wikipedia

   en.wikipedia.org/wiki/Fluorescent-lamp_formats

   One of the first diameters of fluorescent lamps, with the 15W T12 and 20W T12 having been introduced in 1938. These aren't as efficient as newer lamp options. [6] For T2–T12 and T17, the number indicates the tube diameter in 1⁄8 inches, e.g. T2 → 2⁄8 in and T17 → 17⁄8 in.
