Onshape render lighting help?

Having issues getting the lighting to apply to a face or a part. Does anyone know how to get the lighting material to emit light? @GregBrown I have moved the question to here.
I have tried changing the environment in case this scene was too white. Anytime I get the lighting to work, it is never a glowing light, only a white color. Also tried assigning the light material to a part instead of a face.
Thanks in advanced! So excited for Onshape rendering.

EDIT: actually I can get diffuse light to work if bloom radius is 0.05 and threshold is 500000

To add to the topic ...
I found that the "Add Emission" environment to be a little more flexible, allowing the colour to be selected.
Assign "Add emission" environment
Typically the material will first appear black meaning that the light source is "off" (or a low value lumens indicating that it is as good as "off")
Under Appearance -> Global, I set the "unit for emission" to "lumens" (to be consistent with the emitter environments above)
Set the lumens to a big value (eg: 1000, 10000, 100000) to turn the light source "on"
The colour selector in the Appearance -> Global dialogue is fairly self explanatory.
As you can see below, some of the colour rendering can be a bit funky for curved surfaces + low lumens values (the part being rendered below is a singular homogenous part) - haven't figured out what's causing that but it's not holding up my work.
