LED wall sconces can be omni-directional because they can use LED bulbs, like A19s, that are omni-directional. By using omni-directional lighting, light can spread out evenly and can get rid of potential areas with shadows.
For residential spaces, the color temperature will depend on your preferences. If you are using wall lanterns to create a calming feeling outdoors, we recommend that you use warm color temperatures which range from 2000K to 3000K. If you are using the wall lanterns for safety reasons, then we recommend using cool temperatures ranging from 3000K to 4000K.
For commercial spaces, cooler temperatures (4000K to 6000K) increase visibility and give a welcoming environment.
