Experience a restful sleep with our blackout feature and dawn simulation light

Our product eliminates unwanted light from the sun, moon, or street lights, allowing you to create the ideal sleeping environment. When you’re ready to wake up, our dawn simulation light helps regulate your body clock and signals your body to wake up refreshed.

Additional Benefits

Energy Saving

With the world getting hotter, energy expenses are increasing, and it's becoming more of a challenge to maintain comfortable temperatures in homes during summer and winter. Over half the world lives in urban areas which do not get enough natural light to help regulate the body clock. Windows play a vital role in regulating light and heat in our homes. Our invisible technology senses the environment and adjusts to control the heat and light coming from your windows, making your home comfortable.

Smart Control

Control your Belume via a remote, a free companion app or automation to respond to heat/light for energy saving. Have a personal sunrise directly from your window to gently lift you from sleeping to wake up feeling refreshed. Recreate a natural dawn or sunrise to match your schedule. A blackout sleep shade with a wake-up light alarm that gradually brightens to provide a natural wake up.
