When the color is refreshed, it means it will automatically change the color (change one color every day); when the color is not refreshed, the color is fixed.Common problem:How long can it be used and how long is its life span?The life span mainly depends on how you set the automatic switch time of the clock. It is recommended to set it to the off state when there is no one. Generally, it can be used for two or three years. The nominal life span of each tube reaches 10,000 hours. Of course, friends who play with feelings. Generally, I don’t worry too much about the lifespan. Replace which tube is broken. It’s easy to disassemble and assemble.Pay attention:1. The product is a loose part and requires simple assembly and welding by the customer2.The product does not have a glow tube(that is, 4 light bulbs that display numbers)3. The product does not have a battery, if you need to remember the time function, you need to buy an CR1220 battery by yourselfPackage Included:Circuit board X1Acrylic Box X1Screw set X1
