Luminaires with fluorescent lamps were compared to luminaires with LEDs at an ambient illumination level of 300lux. At 5 seating positions and 5 different screen luminance levels, the students were asked to tune the contrast of the letters on the projection screen to 1) a value that corresponded...
LED provides longer life span, better energy efficiency, and selectable light spectra that conventional lighting (such as fluorescent, FL) does not, which attracts more producers to adopt LED lighting on their farms. However, the effects of LED lighting on egg quality compared with conventional ...
CFL vs LED: Which to Choose In the Compact Fluorescent vs LED competition, LED lighting is the hands-down winner in energy efficiency. They are also eco-friendly, long-lasting, and the more adaptable to standard lighting fixtures when compared to CFL. Whether the LEDs are used for business ...

Compared with fluorescent lamps, incandescent lamps, metal halide lamps and high-pressure sodium lamps, which have the disadvantages of high energy consumption and non-adjustable spectrum, phosphor-converted light-emitting diodes (pc-LEDs) have the advantages of close illumination and high efficiency, ...

Compared to the multi-color LED chips packaging method, coating the monochromatic or polychromatic fluorescent powder on the LED chip to achieve white light is more popular and widely applied in the LED industrial due to its correlated color temperature (CCT) adjustability and process flexibility. ...
LCD monitors use cold cathode fluorescent lamps (CCFLs) for backlighting. LED monitors use light-emitting diodes for backlighting. It’s important to note that all LED monitors are actually a type of LCD monitor. The term “LED monitor” is shorthand for “LED-backlit LCD monitor.” ...
