Am I Burning My Phal's Flowers?
 

Alright, this might seem like a silly question but here goes nothing. My current setup consists of a few phals directly under a LED grow light. Most of them are in bloom, and the flowers are about 2 feet above the leaves.

My dilemma is that the flowers are receiving 2x the amount of light that the leaves receive due to them being directly under the grow light. The flowers receive a PPFD of 330 umol/s/m2 while the leaves receive a PPFD of 150 umol/s/m2.

Will this have any negative effects on the plant, such as making the blooms fade faster?

Probably

I would move them out of the "grow light" area - I regularly move my blooming orchids into my living area to enjoy, they go back to their "growing area" when they're done.

I grow most of my phals on shelves, and the spikes definitely hang out close to the lights. I try to keep them from actually touching the lights. Plants that have spikes that go really high get moved when in spike- grocery store phals almost always need to move when in bloom.The ones that bloom on the shelf seem not to be too affected by the extra light, they still bloom for months.

Phals are (mostly) low light orchids, they like the shade.

There's probably a few species that like a little more light (I don't know of any, though), but overall they like shadier spots.
