12 Best Night Lights for Your Home of 2024
Warm-toned lights, especially red or amber colors, are the best options for a night light, regardless of age. "These colors have lower levels of cool blue light and are more conducive to sleep," says Harris. "Personal preference and individual needs can vary, so it''s important to pick the light color that works the best for you.".
