    Black-Light Blue lamps: These lamps are similar to the regular black light lamps, except they use wood's glass as a filter to reduce the amount of visible light emitted. 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 ...

    en.wikipedia.org/wiki/Halogen_lamp

    Like all incandescent light bulbs, a halogen lamp produces a continuous spectrum of light, from near ultraviolet to deep into the infrared. [23] Since the lamp filament can operate at a higher temperature than a non-halogen lamp, the spectrum is shifted toward blue, producing light with a higher effective color temperature and higher power ...

    These bulbs use the same UV-A emitting phosphor blend as the filtered blacklight, but since they do not need to suppress visible light output, they do not use a purple filter material in the bulb. Plain glass blocks out less of the visible mercury emission spectrum, making them appear light blue-violet to the naked eye.

    Some of the least pleasant light comes from tubes containing the older, calcium halophosphate phosphors (chemical formula Ca 5 (P O 4) 3 (F, Cl):Sb 3+, Mn 2+). This phosphor mainly emits yellow and blue light, and relatively little green and red. In the absence of a reference, this mixture appears white to the eye, but the light has an ...

    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).

    The other is to use a phosphor material to convert monochromatic light from a blue or UV LED to broad-spectrum white light, similar to a fluorescent lamp. The yellow phosphor is cerium-doped YAG crystals suspended in the package or coated on the LED. This YAG phosphor causes white LEDs to appear yellow when off, and the space between the ...
