Is this adecuate light for Phalaenopsis?

[Lilac]

I was wondering if anyone coiuld tell me if this is adecuate light for Phals?

They are on a stand inside of the porch.

The porch is shaded by an awning. I have the Dends and Catts on the outside of the porch railing where they get bright shade.

I also have a Miltoniopsis Bert Field Eileen and a Beallara Marfitch Howards Dream on the top shelf of that stand, on the shelf on top of the Phals.

I'm unsure if this is enough light for them to bloom?

Thanks!
