If it is the former, 100 pieces need a voltage of 160V, and the latter requires a tube voltage drop between 200 and 300V.
Chasing stick] is a brand of headlights, not a brand of LED.

The so-called three-color light, in fact, there are only two colors, the third color is actually two kinds of mixed light produced when it is bright at the same time, and your problem is actually that half of the white light beads are not bright, as you can see in the first figure, so it can be judged that there should be a problem with the light source board, one is that the lamp beads are not lit, this situation can only be repaired by the manufacturer, and the second is that the line falls off, which only needs to be connected to the line. But this situation should be dealt with quickly, because the LED lamp uses a constant current drive, for white light, when there is a light source board is not lit, the current will all go to another light source board, that is, in the first case, the part of the lamp beads that are lit is already overloaded, and when it is lit for a long time, the lamp beads will be burned out, that is, only when the second case is lit (only the yellow light is lit and the white light is not lit), it can be used normally, and the other two situations will hurt the lamp beads. Eventually, the white light will burn out (i.e., there will only be one color).
Hello, you can connect your computer directly to the router, so that you can go directly to the Internet without dialing, or you can connect to the broadband modem, which requires dial-up to access the Internet.
Or you can also pair it with yellow or blue, both of which are beautiful colors.
Hello, first of all, thank you for your support to China Telecom. I hope the following can help you, remove the router and connect the network directly through the cat to reach the contract rate, indicating that there is no problem with the broadband, at this time it should be a problem with the wireless router, please restore the router to factory value test, if it still can't reach the contract rate, please replace the router test. >>>More
Yesterday, the screws on the side of the glass side of the inner bud of the glass pane of the headlights were on the floor.
