LED cold light is not the reason why glasses are not suitable, and fluorescent lamps also have cold light. There is a range of temperature for light. Some people prefer a warm environment and choose a light tube with a low color temperature, while those who prefer a cool environment choose a light tube with a high color temperature. However, for household use, do not choose a light tube that is too cold. Choosing a warmer one will feel very warm.

LED lights, whether cold or warm, can harm the eyes. However, every time LED lights are tested during the development stage, there is an eye safety test, which is also required by the international standard IEC62471-1. Many domestic manufacturers do not pay attention to this issue. Famous brands are more at ease.

LED products are mainly used in three major fields: backlight, color screen, and indoor lighting. Due to the fact that backlighting is currently the largest application market for LED, it has driven the rapid growth of the LED industry in recent years. Under the influence of factors such as declining product prices and the rise of a new global ban on incandescent lamps, indoor lighting will replace backlighting as the fastest-growing segment of LED in the future.
