Dataset of spectral irradiance from a set of two Q-Panel UVB-313 40W fluorescent tubes, measured at different temperatures.
qp_uvb313_temp.spctA "source_spct" object with 777 rows (290 nm to 400 nm, 1.0 nm step) and 3
variables.
The variables are as follows:
temperature (C)
w.length (nm)
s.e.irrad (W m-2 nm-1)
Absolute values are comparable among the different temperatures. The lamps and the cosine diffuser were located inside a Conviron growth chamber. The measurements were done with a recently calibrated Macam double-monochromator spectroradiometer located outside the chamber and maintained at constant room temperature of 22 C. After each change in the temperature controller set-point enough time was allowed after the temperature had stabilized inside the chamber, for the output of the lamps to also become stable.
