I imaged my Solux lamp (4700K/50W) lamp with the DAV5 V2.1 spectrometer to test out the 32mm focusing collimation tube assembly and referenced the results to our own solar spectrum using the G5V solar spectrum calibration from RSpec, the capture software I use for this particular camera.

In the above graph, the purple spectrum is our sun, referenced against my solux lamp.

The above pic shows what the spectral image looks like from my Solux lamp spectrum.
