2. Lightbulb socket - Wikipedia

   en.wikipedia.org/wiki/Lightbulb_socket

   A lightbulb socket, lightbulb holder, light socket, lamp socket or lamp holder is a device which mechanically supports and provides electrical connections for a compatible electric lamp base. [1] Sockets allow lamps to be safely and conveniently replaced (re-lamping).

3. Fluorescent-lamp formats - Wikipedia

   These lamps are used for fluorescence effects where less visible light is ideal. 09 N/A Sun-tanning lamps: These lamps produce wide or narrow band UV-B radiation 10 BL Black-Light lamps: Black light lamps give off long-wave UV-A radiation of around 350-400 nm. They are often used to attract insects to traps.

   D – 1.4 V DC filament for Leclanché cells, later low-voltage/low power filament/heater: 0.625 V DC directly heated for NiCd battery, series-heated two-tube designs such as hearing aids. If either filament breaks, further draining of all batteries stops [5] Wide range 0.9 V to 1.55 V DC directly heated for dry cells

5. Bi-pin lamp base - Wikipedia

   en.wikipedia.org/wiki/Bi-pin_lamp_base

   The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...

8. Pulsed DC - Wikipedia

   en.wikipedia.org/wiki/Pulsed_DC

   Pulsed DC (PDC) or pulsating direct current is a periodic current which changes in value but never changes direction. Some authors use the term pulsed DC to describe a signal consisting of one or more rectangular ("flat-topped"), rather than sinusoidal, pulses. [1] Pulsed DC is commonly produced from AC (alternating current) by a half-wave ...

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 ...
