Learn LED candle lamp purchase skills with LED candle lamp manufacturers: 　1. Look at the packaging and trademarks. The state mandates that LED lighting manufacturers’ products mark the following on the outer packaging: rated voltage, voltage range, rated power, and rated frequency. Generally speaking, the trademarks of high-quality products have good printing quality, clear fonts, and are not easy to fall off. Wipe them with a soft damp cloth. The signs are clearly identifiable and difficult to erase. They have the manufacturer's trademarks and related certification marks. Fake and inferior products have poor printing quality, blurred fonts, easy erasure, and no manufacturer's trademark and related certification marks.　　2. The appearance of LED candle light. Good LED lamp manufacturers generally produce products on a large scale. The shape and size of the LED candle lamps produced are consistent and the product quality is guaranteed. At the same time, the shell has no cracks or looseness, and there should be no traces of being pried at the seal. During the installation and disassembly process, the lamp cap should not be loose or tilted.　　 3. The temperature at work. Under normal working conditions, the temperature rise of the LED candle light should be very low. Otherwise, the life of the led candle light will be very short. At the same time, when the candle lamp is lit, there is a quick flicker, or it is very dazzling and fluctuates, which indicates that there is a quality problem in the lamp.　　 4. Start-up performance. There are two characteristics of LED light start-up: one is that the higher the temperature, the easier it is to start; the other is that the lamp will not flash when it is turned off. In addition, it is worth mentioning that many LED lights are very dark when turned on, which is not good for the life of the bulb. LED candle lights should have a power supply circuit and a PCB board inside.　　 5. Check whether the link between the lamp and the lamp holder is loose. The shell of the LED candle lamp will also affect the uniform luminescence of the lamp. Generally, the shell of the candle lamp is divided into two types, transparent and milky white. After getting the lamp, we first check whether the link between the lamp and the lamp holder is loose or tilted. At the same time, the shell has no cracks or looseness, and there should be no traces of prying on the seal. Then use the baffle to check whether the light emitted by the bulb is even on the baffle and whether there are dark spots.
