I also made my colour space to standard.
But, is this the right way of doing it? I know people here have a lot of creative ways of doing things in Blender, I'm curious what one can do to achieve this that doesn't require changing the exposure.
Thanks, Rich Sedman; your solution is the proper solution. I don't know why I forgot about the Add Shader, quite embarrassing.
I'm able to pull down the emission and exposure to one which is what I'm after.
