Question about light intensity in HDRP

Yes, you would have to switch. HDRP is the only renderer for Unity that uses physical light values.

• Lux (for Directional Light/Sun/Moon)
• Lux, Lumens, Candela, Ev 100 (for Point/Spot Lights)
• Lumens, Ev 100, Nits (for Area Lights)

Have a look at these guidest

Oh! Thanks a lot for your help and reply.
Does it allow measuring the lighting intensity of a combination of lights in an area as well?
