The CDB support light types. When you publish, you specific the light type. It is then up to the renderer to map those types to color and intensity. This forum being about the CDB specification, this is where I will stop. You will need to engage with the renderer solution provider to understand how the mapping to the light are done and how to impact the visual effect of it.
I hope this answers the CDB spec question.
I am currently conducting builds with airfield lighting. However, the lights are not very bright. Is there anyway to increase the intensity of airfield lights?
