How to create a Blue LED light with D5 render

Hi all,

I am trying to create a Blue led light like the image below but my result is not so close. How can I improve it? the more intensity I put in the more white bright it becomes.

Thanks

Hi, I think you can adjust the emissive color as well


Do not forget to turn on Cast shadow option.
I found this one in D5 facebook community, which seems what you want.
