new home orbs

My mom passed away after a long illness at home in January, with all of us surrounding her with love. My Dad has been having a hard time, but decided to move to a different state where he has more friends and extended family. He just arrived at his new home this week and has begun setting up his things. He sent me this photo from his new living area, and I was stunned at the number and brightness of orbs around the room. I would love feedback from those with some knowledge and experience here; I only know very little about orbs. Thank you and blessings, Amy
