Nichia NSPB510BS, 5mm-LED, 4700mcd, blue
With 24% Nichia is the largest LED manufacturer in the world and inventor of the blue (and so also white) light emitting diode. The innovative Nichia research department is a pioneer when it comes to efficiency and establishes records on a regular basis.
Durability, brightness and homogeneity are among the major strengths of the Nichia brand. Further, the fine selection allows a large added value for professional processing.
In a long-term laboratory study with more than 50 different white LED types and several thousands of individual measurements, LUMITRONIX detected a much longer durability as well as a significantly lower degradation (loss of brightness) of Nichia LEDs compared to the average of all other light emitting diodes.

|Luminous Flux (lm) |
Luminous Flux (lm)
The luminous flux (lumen)
describes the total quantity of light provided (independent of the angle of beam).

Wave length (nm)
The dominant wavelength
indicates the perceived colour of a source which is not monochromatic but in the CIE colour space. Most actual LEDs are near the pure colour curve but not on it. When connecting and extrapolating the points W (white) and P (sample), the intersection with the colour curve yields the dominant wavelength. The dominant wavelength can further be explained via the spectrum. After assessing the spectrum of the source using the V(λ) curve, the spectral centroid is determined. The dominant wavelength provides the most accurate information about the perceived colour of a source.
|Viewing angle (°) |
Viewing angle (°)
The angle of beam
describes in what angle the light is directed forward.
|Power consumption||0 W|
|Voltage (V) |
The voltage (V)
mentioned can be impressed on the product. If your initial voltage is higher (e.g. Car-voltage or adaptor), then you will need a resistor.
