Is there anyway I can measure the illuminance level on a surface?

    I am trying to design a lighting experiment using Unity. I have different types of lighting in a scene and now I need to know the illuminance level (lux level) on a surface in an environment that I have designed. Is there any way that I can do that? or any plug-ins that I can use? I am not using HDRP but I realized it uses physical light units, though I am still not sure if it means I can get an illuminance value on a surface using that either. Should I switch to HDRP?

    I will be grateful if anyone could help me, I am new to this. Thanks!

    HDRP gives you access to this information through their color picker which is part of the debug window for HDRP. It's under the Rendering Panel section.

    Thanks for helping. Although, can you please be more specific? I get the RGB values and other things under color picker but I couldn't find any information about light level.
