In the current domestic market, LED lamps mainly have two types of wiring methods: single -ended wiring and dual -end wiring. Through comprehensive analysis of the above two forms, we can see that Philips that use single -end wiring methods are safer. A brand products are relatively safe, but IEC does not allow switches and does not meet standard requirements. The other three products with dual -end wiring are greater than 0.5 mA, and there is a risk of electric shock during the installation process.

     According to the International Electricity Commission (IEC) standards, single -ended wiring is safer than the dual -end wiring method. However, due to the relatively low price of the two -end wiring LED lamp tube, and the knowledge of hidden safety hazards has not been popular, consumers often mistakenly choose the two -end wiring LED lamps when buying products. In addition, the wires need to be changed during the installation of single -end wiring and dual -end wiring, but many people subconsciously believe that the single -end wiring to change the wire is more complicated. To this end, the double -end wiring LED lamp pipes are popular in China, bringing huge safety hazards to consumers.

     In the above tests, although Philips and A brand products are outstanding in terms of security, the brand A brand uses the transition scheme of the dual -end wiring additional switch. In addition to increasing the difficulty of changing the line, it does not meet the IEC security standards. , It will cause trouble to use. If the lamp is installed, the electrician forgets to turn on the switch on the lamp, and the wall switch below does not respond. It can be seen that the Philips LED T8 lamp tube is more advantageous in terms of installation convenience and security. It meets the relevant standards of IEC and provides important guarantees for consumers' lives and property.
