Baby sleep

Hello everyone so I’m not sure what to do. so the baby sleep people say keep the room pitch black for the optimal sleep space and so I have been doing that. He is a prettu darn good sleeper for the most part and can sleep in the day with some light but I feel like at night if like a phone screen or something is on he wakes up. So I bought the slumber pod for trips because my husband likes to watch videos before bed but im like am i hindering my baby from sleeping through things like light? What do you all think? I also am not sure about the slumberpod, it seems stuffy even with the fan and vents open to me. Pic for fun (:
