2. Glow stick - Wikipedia

   en.wikipedia.org/wiki/Glow_stick

   The dyes used in glow sticks usually exhibit fluorescence when exposed to ultraviolet radiation—even a spent glow stick may therefore shine under a black light. The light intensity is high immediately after activation, then exponentially decays. Leveling of this initial high output is possible by refrigerating the glow stick before activation ...

3. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_lamp

   High-intensity discharge lamps are a type of arc lamp. Brand new high-intensity discharge lamps make more visible light per unit of electric power consumed than fluorescent and incandescent lamps, since a greater proportion of their radiation is visible light in contrast to infrared. However, the lumen output of HID lighting can deteriorate by ...

4. Polilight - Wikipedia

   en.wikipedia.org/wiki/Polilight

   The PL500 ('500' refers to the power in watts of the xenon arc lamp) has eleven monochromatic bands, a ‘blank’ position that provides high intensity white light in the range from 380 to 650 nm and an optional infra-red output suitable for document examination.

5. Hydrargyrum medium-arc iodide lamp - Wikipedia

   en.wikipedia.org/wiki/Hydrargyrum_medium-arc...

   HMI lamps are approximately the same color temperature as the sun at noon (6000 K), and like other high intensity discharge lamps which contain mercury, generate ultraviolet light. Each HMI fixture has a UV safety glass cover that should be used to protect people who may be in front of the light.

6. Deuterium arc lamp - Wikipedia

   en.wikipedia.org/wiki/Deuterium_arc_lamp

   A deuterium arc lamp (or simply deuterium lamp) is a low-pressure gas-discharge light source often used in spectroscopy when a continuous spectrum in the ultraviolet region is needed. Plasma "arc" or discharge lamps using hydrogen are notable for their high output in the ultraviolet, with comparatively little output in the visible and infrared.

7. Ceramic metal-halide lamp - Wikipedia

   en.wikipedia.org/wiki/Ceramic_metal-halide_lamp

   Ceramic metal halide lamps use one fifth of the power of comparable tungsten incandescent light bulbs for the same light output (80–117 lm/W) and retain color stability better than most other gas discharge lamps. Like other high-intensity discharge lamps, they require a correctly rated electrical ballast in order to operate.
