Enough artificial lights for phals and oncidium?

[Mercurianmad]

Hi guys. I’m trying to get all of my plants off of the windowsills and onto one shelf.

Here is a picture of the shelf at the top are three small fig trees. They’re dormant obviously. And they need full sun. On the middle shelf are my high light orchids, cattalya, vandas and cymbidium. On the bottom shelf on my low light orchids, phals and oncidium. Is this artificial light producing enough light for my phals and oncidiums on the bottom shelf. I can’t dim it because my orchids on the middle shelf need the high light.

The last picture is natural light, without the artificial light
