|Part NO||Emitting Color||Intensity per LED||Intensity||Beam Angle |
Beam angle is used to express the width of the light emitting from the source. The narrower the beam angle the more focused the light energy is. Comparing two 40 watt lights one with a beam angle of 30(a) and another with a beam angle of 90(b), They both produce the same amount of light output but (a) will appear brighter in the beam angle compared to (b) at the sacrifice of light spread.
Royal Blue is binned by radiometric power and peak wavelength rather than photometric lumens and dominate wavelength
|CCT / Wavelength |
CCT is used to express the color or shade of white light. The Correlated Color Temperature is the measure of the color appearance of the light emitted from a light source, measured in degrees kelvin (K). The CCT rating is a general 'warmth' or 'coolness' measure of its appearance. Wavelength is used to express a specific color of light other than whites. Wavelength is the portion of the visible spectrum that the human eye can detect, between 380 and 700 nanometers (nm). When trying to match an existing bulb color choose a replacement that most closely matches the CCT or wavelength of the original.
