2. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   As illustrated by a straight line on the chromaticity diagram, simple two-white blends will have a pink bias, becoming most severe in the middle. A small amount of green light, provided by another LED, could correct the problem. [41] Some products are RGBWW, i.e. RGBW with tunable white. [42] A final class of white LED with mixed light is dim ...

   en.wikipedia.org/wiki/LED_filament

   A 230-volt LED filament light bulb, with a B22 base. The filaments are visible as the four yellow vertical lines. A LED filament light bulb is a LED lamp which is designed to resemble a traditional incandescent light bulb with visible filaments for aesthetic and light distribution purposes, but with the high efficiency of light-emitting diodes (LEDs).

6. 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. Lamp bulbs with dual carbon filaments were ...

7. Coleman Lantern - Wikipedia

   en.wikipedia.org/wiki/Coleman_Lantern

   The Coleman Lantern is a line of pressure lamps first introduced by the Coleman Company in 1914. This led to a series of lamps that were originally made to burn kerosene or gasoline. Current models use kerosene, gasoline, Coleman fuel or propane and use one or two mantles to produce an intense white light.
