Your birds do not need to maintain a minimum distance from our HappyBird lamps. Our lamps are completely safe at any distance. The lamps were developed specifically for birds, so you can be completely confident that the light emitted is tailored to their needs.
You also don’t need to worry that the light is too bright. Unlike conventional lighting, where the entire light often emanates from a single point, our many LEDs are distributed across the entire length of the lamp housing, ensuring that no single spot of light is too bright.
