Is the bulb crooked but bright when screwed up?

The light bulb turns on when you screw it on, indicating that your bulb switch is not turned off. Turn the switch off and then screw.

The first thing to do when installing a light bulb is to make sure the power is turned off, and if you are unsure, you can turn the electric switch at home first.

Pull it down, then find a high stool to step on, hold the bulb holder in one hand and twist the bulb with the other, of course, the force should not be too large, otherwise it will be easy to break the bulb, scratch yourself, unscrew the bad one and then press the good one, so that you can, after the bulb is installed, turn on the power supply to see if it is energized.

The bulb is broken, but it is still slightly shiny, in fact, it is useless, it should be replaced with a new one, no matter what kind of bulb it is, it has a certain service life, but different brands of bulbs are used for a long time.

Big brands must take a longer time, and the quality of some miscellaneous brands is not very good, of course, the time to use is short, and even accidents will occur. Hopefully, you'll be looking at big brand bulbs when you buy them, so they're guaranteed.

In China, the screw bulb on the market (including online**) has been popularized and standardized; For screw bulbs, they are crooked but bright when screwed up; It is because the thread is not aligned when the screw bulb is screwed up, and it is screwed to the end;

The bulb is crooked but bright when screwed on, and can be used continuously; However, for the reason of changing the screw bulb in the future, it should be unscrewed and gently screwed up by the thread of the lamp head!

If it is "crooked" if it is re-screwed, it means that the bulb is not properly connected to the screw! But it doesn't affect the use!

A bulb is crooked when screwed up, indicating that its screw mouth was made. There is a problem. However, it does not affect his normal hair volume. This is normal and belongs to the defective product in the product.

This does not affect the use, it should be the silk of the silk head is not right, but there is no problem with the use.

Summary. In the case that the lamp head is qualified, and the installation and wiring are correct, the power supply voltage is normal, and the power is normally energized, there are two main reasons: first, the lamp is good, but when the lamp is installed, it is not screwed in place, there is still a gap between the lamp and the lamp head, and the contact is not touched.

Second, when the lamp leaves the factory, the inspection is unqualified, and it is shoddy, which is a bad lamp.

The same LED bulb screw, why does it not light up when screwed on?

In the case that the lamp head is qualified, and the installation and wiring are correct, the power supply voltage is normal, and the wheel is often energized, there are two main reasons: first, the lamp is good, but when the lamp is installed, it is not screwed in place, and there is a gap between the lamp and the lamp head, and the contact is not touched. Second, when the lamp is out of the Luzhong factory, the inspection is unqualified, and it is shoddy, which is a bad lamp.

Check the wiring to see if the lamphead wire has fallen off, it feels either unscrewed or broken, and it should be okay to go to the store to change it.

The problem is that the previous one is bright, and if you buy a new one today, it won't light up, and when you try to buy it, it will also be bright.

The electric switch is open, right, it's tightened, right?

It's not lit up, it's a bulb problem<>

I went crazy on the road.

The problem is that the four of them don't light up, and the old ones light up when they are installed.

I thought there were several types of threaded lights [AWSL].

I thought there were several types of threaded lights [AWSL].

If it weren't for the fact that the switch wasn't on and the bulb was tightened, there shouldn't be any other problems.

That's the problem with the lights<>

That's the problem with the lights<>

If the snail pattern is screwed up, there is no problem if it can be matched.

As long as it's threaded, it doesn't matter, right?

Energy-saving lamps also have light bulbs.

The threads are not separated.

They are all energy-saving lamps.

I studied electrical, so I think it's <> the light bulb problem

Good. That's the light bulb problem.

Summary. The same LED bulb is screwed to another place, but the bulb does not light up.

It may be that the bulb is not in good contact, or it may be that the screw is not charged in the first place, so it does not light up.

It may also be that the voltage of the other screw is not enough for the voltage of the bulb, so the bulb will not light up if it does not work properly.

The same LED bulb screw, why does it not light up when screwed on?

The same regret is that the LED bulb is screwed to another place, but the bulb does not light up. It may be that the light bulb is not in good contact, or it may be that this screw mouth is not charged by Suishan shelter, so it is not lit. It may also be that the voltage of the other screw is not enough for the voltage of the bulb, so the bulb will not light up if it does not work properly.
