Our products are safe for home use. All projectors are supposed to be safe around children and pets, as their range is about 625 sq ft, therefore they shine furthest away about 100 ft. It is highly unlikely they will have any impact on aircraft or helicopter traffic.
However, we advise you don’t point them straight up, but let them shine on a surface (house, tree, garden) so you can enjoy the full effect without any aerial concerns.
