2. Fluorescent-lamp formats - Wikipedia

   en.wikipedia.org/wiki/Fluorescent-lamp_formats

   Numeric code Alphabetic Code Fluorescent lamp type Notes 05 N/A Germicidal lamps: No phosphors used in these lamps at all, and the enveplope is made of fused quartz instead of glass. In the American lamp code, the F as in FxxTyy is replaced by a G as in GxxTyy, indicating that it's a germicidal lamp. 08 BLB Black-Light Blue lamps

3. 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 ...

4. 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 [7] (or its inch-based equivalent, the A19 bulb [2] [4]), which is 60 mm (19 ⁄ 8 in or 2 + 3 ⁄ 8 in) wide at its widest point [3] and approximately 110 mm (4 + 3 ⁄ 8 in) in length. [8] Other sizes with a data sheet in IEC 60064 are A50, A55, A67, A68, A71, A75, and A80.

5. Photoflood - Wikipedia

   en.wikipedia.org/wiki/Photoflood

   Photoflood lamps are a type of incandescent light bulb designed for use as a continuous light source for photographic lighting. [1] The filaments of such lamps are operated at much higher temperatures than is the case for standard, general lighting service lamps. The result is a brilliance of light much higher than the lamp's wattage rating ...

6. Floodlight - Wikipedia

   en.wikipedia.org/wiki/Floodlight

   The most common type of floodlight was the metal-halide lamp, which emits a bright white light (typically 75–100 lumens/Watt). Sodium-vapor lamps are also commonly used for sporting events, as they have a very high lumen to watt ratio (typically 80–140 lumens/Watt), making them a cost-effective choice when certain lux levels must be provided.

7. 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]
