WebThe most popular type of tricolour light emitting diode comprises of a single Red and a Green LED combined in one package with their cathode terminals connected together producing a three terminal device. They are called tricolour LEDs because they can give out a single red or a green colour by turning “ON” only one LED at a time. WebFeb 6, 2014 · Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture. Sometimes one may hear that plants don’t use green light for photosynthesis, they reflect it. However, this is only partly true. WebDec 2, 2024 · Whenever I see color High Power LEDs (for example green 3W on Star) I see disappointing efficiencies: For 520 nm the theoretical efficiency is 683 lm/W * 0.88 (green) = 601 lm/W. But most are described with 110 lm / 3W ( Example )= 37 lm/W which is a conversion of electricity to light of 6%. inc002vfbk
