LED simulation

Hello list,

I would like to simulate LED lights in order to compare them with
fluorescent ones. The simulation process remains the same and i have to
change only the geometry and the data of the light source or something
completely different is required ?

Thank you in advance.

What are you trying to compare? If just the distribution and intensity, and you are looking at an LED luminaire or lamp that has been tested per IES LM-79 and you have a properly formatted (IES LM-63) .ies file as a result, then yes, the process is the same as for fluorescent. Simply create radiance lights with ies2rad for your two (or more) luminaires, and color balance by defining them all as "white" light sources (with the -t option in ies2rad).

Hi Rob,

I see the point, I have to change the light properties. I just found that
companies provide technical data for their LED models.

Thank you for the answer
