Yes, a lightbox can get hot depending on the type of light source used and the duration of use. Lightboxes typically use LED lights, which are known for their energy efficiency and minimal heat output. However, if the lightbox is left on for an extended period of time, the LEDs can generate some heat, which may cause the box to feel warm to the touch.
It's important to note that the heat generated by the lightbox is generally not a safety concern, as LED lights are designed to dissipate heat efficiently. However, it's always a good idea to follow the manufacturer's instructions and not leave the lightbox on for extended periods of time without giving it a chance to cool down. Additionally, it's important to make sure the lightbox is not placed in a location where it can overheat or cause a fire hazard.
