Introducing Harth Lighting Humans. Our journey began from a simple desire for better sleep. That's why we developed the Nite-Nite Light Bulb, designed to improve your sleep with the best LED light . With over 30 years in the lighting industry, we, as a family-owned business, are dedicated to creating solutions for healthier sleep habits. We're driven by a passion for improving family health and well-being, and we're excited to share our mission with you.
