Glyph of Holy Light with Valanyr and Trinkets

I have a question about how works the glyph of holy light with the valanyr and meteorite crystal,
With the valanyr, does the healing effect of the glyph put a shield to the 5 nearly members or only if u made a direct heal?
And about the meteorit, it stacks with the healing effect of the glyph or only benefits with the Beacon of Light?

Thanks.
