cattleya walkeriana light pollution tips?

[OrchidNut555]

Hey everyone! First of all; Happy new year!

i decided to bite the bullet and get a cattleya walkeriana and i had been wondering about some good ways to limit light pollution at night since this plant is very sensitive to it in terms of blooming or not blooming.

my current setup is a milsbo cabinet with grow lights inside it that also generate some warmth which results in the perfect temperature for my warm growing orchids (around 23 degrees celsius). the lights turn off at 7 pm and then there is some light from the kitchen and tv on the other side of the living room that hit the cabinet. currently this is the only place where i can put the milsbo cabinet.

i was wondering if any of you had any ideas on how to limit light pollution once the lights turn off? maybe there's some sort of setup i could use or some household trick i hadn't thought of yet.
