inquiry on the possibility of colored LED light simulation in Radiance

Hi All,

Currently I was involved in a research on how different coloured LEDs and
the optimal intensities affect plant growth and qualities.

After reading through some info online, I know that it is okay with
simulating sunlight in Radiance but am not sure if it is possible to
simulate different coloured LEDs (such as red , blue, orange, etc)?

Regards,

Alex
