Is the color of the LED corn lamp bead consistent when lit?
There are many small packaging factories because they do not have color distinguishers. It will be illuminated that the luminous color of the lamps and lanterns is different, so it is difficult to guarantee the quality.
LED corn light workmanship
Generally, under normal circumstances, it is processed by fully automatic machines, with exquisite workmanship and a good appearance. If the workmanship is not good, it means that it is done manually, which proves that the company is not strong.
Shell material of LED corn lamp
Generally, corn lamps use aluminum lamp body and plastic lamp holder. Aluminum not only has a beautiful and smooth appearance without roughness, but also has good heat dissipation performance.
Brightness of LED corn lights
LED lamps with different brightness have different prices, and there is a certain gap between the prices of ordinary brightness and high-brightness LED lamps. Therefore, when customers understand, they must clearly know what kind of brightness they need, so that they can accurately position their products, so that manufacturers can give you accurate prices.
Finally, remind customers not to blindly pursue low price and low price when choosing LED lamps. Sometimes low-quality LED lamps are not as long-lived and bright as traditional lamps, which also loses the meaning of high brightness and long life of LED lamps.
LED corn lamps with E27 and E40 lamp bases:
- The characteristics of the LED corn light itself: the unidirectionality of light, no light diffusion, and ensure the lighting efficiency. the
- This LED corn lamp adopts a 360-degree light-emitting structure design, omni-directional lighting, no dead angle, E27 lamp head, and a wide range of applications. the
- The light source efficiency of LED has reached 110-130lm/W at present, and there is still a lot of room for development, with a theoretical value of 2800m/W. The luminous efficiency of high-pressure sodium lamps increases with the increase of power. Therefore, the overall light effect of LED street lights is stronger than that of high-pressure sodium lamps.
- The light color rendering of LED garden lights and street lights is much higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of LED garden lights reaches more than 75. From the perspective of visual psychology, it can achieve the same brightness. LED garden lights The average illuminance of the lamp can be reduced by more than 20% compared with the high pressure sodium lamp
How to repair corn light led lights?
First of all, we need to make sure that there is no problem with the circuit where the LED lights of our own family are located. The main problem will be the switch, which is the focus of our inspection. Check the power converter on the back of the LED light. Just remove the converter, and then use a multimeter to measure the voltage or current. If the power converter is damaged, you can buy a replacement directly, which is generally very cheap.
If there is no problem with the power converter of the LED lamp, then we can switch the multimeter to the voltage output gear, and then put it on the positive and negative poles of the corresponding LED lamp beads to see if it will light up. If it doesn’t light up, just replace it. Generally, after the above three steps, 90% of the problems of LED lights can be solved, so that our LED lights can regain their due brilliance.
Which corn led light is better?

Corn led is equal to how to remove the lampshade?
The corn led is equal to the lampshade first, turn off the switch, and with the help of a folding ladder, remove the shell of the LED ceiling lamp, and check whether the lamp tube appears black and dark. If there is, it is likely that the lamp tube has been damaged. It must be replaced. This kind of LED light tube can be bought in the hardware store. It is recommended to choose a well-known brand.
First remove the lampshade, remove the fixing screws, or use a straight hand to hold the lampshade firmly, so as not to drop the lampshade and break it, then slowly turn the lampshade counterclockwise, so that it can be removed.
Secondly, if the lamp tube is still in good condition, you should try to tighten the lamp tube joint to see if there is any poor contact. This situation is relatively simple to operate and is also easy to happen.
Price and specification of led corn light:
The general specifications of LED corn lights are mostly: between tens of watts and several hundred watts. as follows:
8W, 12W, 20W, 40W, 60W, 80W, 100W, 120W, 150W, 140W, 120W, 200W, 250W, 300W.
Most of the price range is: 3$~200$. This price is not expensive in LED lamps, and it has a long lifespan, which is very cost-effective to use.
