LED ENGINE CONFIGURATION
The SPECTRA TUNE HCL contains ten LED channels for multispectral reproduction. The
characterization of each LED is shown in Table 1 and Figure 2*

* Measured at 25°C. Dominant wavelength and amplitude of some channel may vary slightly
depending on bin availability at the moment of the manufacturing; however, the individual
calibration of each SPECTRA TUNE HCL would be taken in account internally to correct any
eventual deviation and produce the desired spectrum.
