2. T5 retrofit conversion - Wikipedia

   en.wikipedia.org/wiki/T5_retrofit_conversion

   T5 retrofit conversion can maintain existing lighting levels with the higher efficiency of the T5 lamp. However, with kits that operates the lamp on the existing magnetic ballast, the efficiency drops and the lamp life is considerably shortened, as T5 lamps aren't designed to be operated on mains frequency but only on high frequency.

3. Fluorescent-lamp formats - Wikipedia

   en.wikipedia.org/wiki/Fluorescent-lamp_formats

   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-Light lamps: Black light ...

4. Wedge base - Wikipedia

   en.wikipedia.org/wiki/Wedge_base

   LED sets also have special bases that enforce electrical polarity, and keep them from being used in incandescent sets. Philips-branded sets and most store brands use an offset, with the longer anode (positive lead) being lower and the shorter cathode (negative lead) being higher on the wedge base. GE-branded sets (no longer actually made by GE ...

5. Fluorescent lamp - Wikipedia

   en.wikipedia.org/wiki/Fluorescent_lamp

   Fluorescent lamp efficacy is dependent on lamp temperature at the coldest part of the lamp. In T8 lamps this is in the center of the tube. In T5 lamps this is at the end of the tube with the text stamped on it. The ideal temperature for a T8 lamp is 25 °C (77 °F) while the T5 lamp is ideally at 35 °C (95 °F).

6. Light-emitting diode physics - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   The wavelength of the light emitted is a function of the band gap of the semiconductor material used; materials such as gallium arsenide, and others, with various trace doping elements, are used to produce different colors of light. Another type of LED uses a quantum dot which can have its properties and wavelength adjusted by its size. Light ...

7. Volvo V70 - Wikipedia

   en.wikipedia.org/wiki/Volvo_V70

   The Volvo V70 is an executive car manufactured and marketed by Volvo Cars from 1996 to 2016 across three generations. The name V70 combines the letter V, standing for versatility, [1] [2] and 70, denoting relative platform size [3] (i.e., a V70 is larger than a V40, but smaller than a V90).
