A collection of lamp emission spectra for an Aputure Amaran pocket-sized daylight-balanced LED light type AL-M9.
amaran_m9.mspctamaran_m9.mspct is a "source_mspct" object containing
a collection of 6 "source_spct" objects as members. Members are
named.
amaran_m9.mspct contains a collection of
"source_spct" objects with spectral emission data for six different
dimming settings. The lamp was maintained at the same distance of 160 mm
from the input optics of the spectrometer. In all cases the diffuser was
kept in place. Thus, the different spectra are comparable and provided
expressed in calibrated spectral energy irradiance units.
This light source has 9 LEDs in a 3 \(\times\) 3 grid. The LEDs are in SMD packages. A built-in Lithium battery powers it. It comes with a detachable plastic diffuser
The variables in each member spectrum are as follows:
w.length (nm)
s.e.irrad (\(\mathrm{W\,m^{-2}\,nm^{-1}}\))
