How does the use of optical accessories work? Does the diffuser make the light relatively soft?
The diffuser can make the light slightly softer but it is such a small light it won't really be that soft. What it really does is spread the beam wider. If you want really soft light you can bounce a light off of a white card or through some fabric,
How do you set this light to white? mine only does rgb, and scene mode.
Friends, this light is RGB light and cannot cast white light
