FAQ

How do the fluorescent tubes fail?

Basic about $15 a good lamp, spend money to repair it is better to buy a new one, and that no repairability, warranty, will usually give you a new selling

Why don't leds need a rectifier

Leds also require a power supply to drive only the rectifier that is not the tube. Normal LED daylight tubes are not driven. You have to have a power supply drive, and you have a built-in driver but that's going to affect the life span of the power supply and you don't have to be able to do that without the wiring.

How does the lamp line connect

If it is converted by fluorescent lamp tube into LED lamp tube, want to remove the regenerator and the ballast. The two wires connected to A1 and A2 have been turned into a thread, and the two wires connecting B1 and B2 are also twisted into one line and are connected to the two ends of 220V respectively.

How do I get the four joints of the LED fluorescent tube, and I'm going to do any two of them that can search through the AC220V to light up, and not make the wire and the zero line together? thank you

The LED fluorescent tube In fact, it is the connection column of the ordinary daylight lamp, the four connecting bars, each of which is 220V The LED fluorescent tube, which is connected to the AC DC transform at 220V, gives the internal LED power supply According to the internal implementation of the LED tube (whether the two ends are in parallel) At least two terminals at one end, which can be lit up by 220V, may be connected in parallel to this end, or an empty terminal

Is an LED 20 watt equivalent to 40 tubes?

The normal fluorescent tube is 40-60lm/W, and the fluorescent tube of 40W is between 1600 and 2400LM LED light effect 90-120lm/W, 20W LED tube light effect in 1800-2400LM So if the quality LED tube is completely replaceable, please refer to the lamp tube of shenzhen fangco lighting

Why is it that when my electric car is charged, the light bulb is burning in the house, and the incandescent lamp is fine, and the other appliances are normal

It is possible that the high frequency pulse of the charger inside the charger is flowing into the power grid, causing the fluorescent lamp ballast to work and burn down. Electric car charger belongs to the circuit structure of the switching power supply, and the internal vibration circuit is used to produce high frequency signal to drive the transformer. Please use the TV interference method to test electrical good or bad. Put the charger in the TV next to blunt electricity. Television will have interference image will solve the problem that there is something wrong with the charger repair and replacement..

Does daylight bulbs damage electronic lamp heads?

Will you get the power wrong? Maybe there's some protection on the lamp that the developer has lost, if you're the new one, you're going to go to the dealership.
