    en.wikipedia.org/wiki/SMD_LED

    The light from white LED lamps and LED strip lights is usually provided by industry standard surface-mounted device LEDs (SMD LEDs). [2] Non-SMD types of LED lighting also exist, such as COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package. A single multicolor module may ...

  5. Luminous flux - Wikipedia

    en.wikipedia.org/wiki/Luminous_flux

    Luminous flux (in lumens) is a measure of the total amount of light a lamp puts out. The luminous intensity (in candelas) is a measure of how bright the beam in a particular direction is. If a lamp has a 1 lumen bulb and the optics of the lamp are set up to focus the light evenly into a 1 steradian beam, then the beam would have a luminous ...

    en.wikipedia.org/wiki/Worklight

    In theater, a worklight is a high-intensity light fixture which is used to illuminate the stage for the benefit of technicians. Technicians use these lights, rather than the stage lights for a number of reasons. Firstly, it takes much less technical knowledge to turn on worklights, so even people with no knowledge of electrics can turn them on.

  7. Lumen (unit) - Wikipedia

    en.wikipedia.org/wiki/Lumen_(unit)

    A 470-lumen LED lamp. It consumes about one sixth the electrical power of an incandescent light bulb producing the same light. Lamps used for lighting are commonly labelled with their light output in lumens; in many jurisdictions, this is required by law. A 23 W spiral compact fluorescent lamp emits about 1,400–1,600 lm.
