The small diagonal cylinder at the bottom of the arc tube is a resistor which supplies current to the starter electrode. A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. [ 1] The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger soda ...
Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source.

The Apple IIe added "double" versions of each of these, most prominently ...
Phase-out of incandescent light bulbs. Various governments have passed legislation to phase out manufacturing or importation of incandescent light bulbs for general lighting in favor of more energy- efficient alternatives. The regulations are generally based on efficiency, rather than use of incandescent technology.
