FAQ What is the lifespan of a laser projector? The laser projector’s lifespan typically ranges from 20,000 to 30,000 hours with regular use, surpassing that of traditional lamp-based projectors, which typically last between 3,000 to 5,000 hours. Eco or dimmed brightness settings can further extend a laser projector's lifespan to around 40,000 hours or more. How is a laser projector different? Laser projectors use lasers as their light source, while traditional ones use lamps or LEDs. They offer a longer lifespan (often 20,000 to 30,000 hours or more) compared to the typical 3,000 to 5,000 hours of lamp-based projectors. Laser projectors provide brighter, more vibrant colors, warm up instantly, are more energy-efficient, and maintain consistent brightness over time. They also tend to produce less heat and can be more compact and flexible in terms of placement. Are laser projectors safe for the eyes? Yes, laser projectors are designed to be safe for the eyes under normal viewing conditions. When delving into how laser projectors work, you'll find that viewers typically see the light after it's diffused and reflected off a screen, ensuring it's not directly harmful. These projectors also adhere to strict safety standards to regulate light energy emissions. However, as with any screen, it's advisable not to stare directly into the light source and to take breaks during extended viewing.
