Phal. too close to light?

[Dreshanda]

(Hopefully the photo attached properly...)

Hey all! New here, litterally just joined to ask this question.

The pictured Phalaenopsis is approximately 18 inches tall, and the flowering heads are only about 5 or 6 inches away from the light source. The leaves, however, is about 24 inches away from the light source.

My question is, will this harm my Phal? The flowers, or the foliage? The last time I kept orchids of any kind, I lived in a warmer climate than I do now and kept them on my windowsill year round. Here...well, the window gets frosty most of the evening, so I need to keep it under a grow light. I have a humidifier set up in this corner of my apartment as well, so I'm not too concerned about humidity. Just wanna make sure I'm not going to scorch my new plant.

Also, anybody have cats? Do they try to eat your orchids, and how do you stop them?

Thanks in advance for any help, and I hope y'all have a fantastic weekend!
