- LIGHT SPECTRUM
The family name SPECTRA has been inspired by the visible light spectrum, i.e. the portion of the electromagnetic
spectrum, whom the human eye will respond to (from about 390 to 700 nm).
The more uniform is the light spectrum of an emitting light source, the better the quality of the emitted white light.
When it comes to photography and videography, the light spectrum of the light source has extreme relevance,
since it has a direct impact on the quality of the fi nal result. Professional videographers and/or photographers need
LED light sources having a uniform spectrum, without a peak of intensity at a wavelength of 520570 nm,
correspondent to green light.
LEDs used in SPECTRA LED fi xtures are customized for Manfrotto, to better suit to video and photo applications.
Moreover, components are selected among production batches, in order to guarantee the same level
of performances for each and every LED device.
In this document, a comparison between the light spectrum of different light sources is presented.
LEDS EMBEDDED IN MANFROTTO SPECTRA LED FIXTURES.
The light spectrum of Manfrotto LED fixtures is shown below. Note uniformity of the relative intensities across
the visible light spectrum. No peak in the green area is visible. LED have been optimized for color temperature,
CRI, and brightness.

SUNLIGHT
The sun is a black body thermal radiator and thus emits close relative intensities of wavelengths
across the visible spectrum.
