The Kabu light box is a device used to display images and text, usually composed of lights and transparent films. Theoretically, the Kabu light box itself does not release harmful substances.

However, if low-quality films or inks are used, they may contain harmful substances. For example, some cheap printing materials may release volatile organic compounds (VOCs) such as benzene, formaldehyde, etc. Prolonged exposure to these harmful substances can have negative effects on human health, especially in a closed environment like a bedroom.

In order to reduce the risk of exposure to potential harmful substances, it is recommended to choose high-quality, environmentally friendly Kabu light box products, and ensure that the transparent film and ink comply with relevant safety standards. Additionally, you can keep the room well-ventilated and avoid prolonged exposure around light boxes.

In summary, if you choose a high-quality Kabu light box that meets safety standards, use appropriate films and inks, and pay attention to ventilation and personal protection during use, Kabu light boxes should be placed in the bedroom. Usually no obvious harmful objects are produced.
