In 2013, the LED lighting industry entered a hot stage, LED light bar and custom light bar gradually entered a wide range of applications. The two light bars commonly used in outdoor lighting are: LED wall washer light and LED linear light. Both of these LED products have the characteristics of energy saving, high luminous efficiency, rich color, long life and good waterproof performance. So after 2013, the light bars of other light sources were gradually replaced by the current LED wall washer light and LED linear light. There are various types of LED pixel bar products on the market. How can I buy a satisfactory light bar? This requires a certain understanding of its products before purchasing, so that it will be handy when purchasing.


1. Pay Attention to LED Light Source

In order to make the light bar achieve a certain brightness, what we need to pay attention to in the selection of the light source is that the design of different lamp beads is different, so the heat dissipation effect is also different, and of course the light effect is also different. As a new generation of light sources, LED light sources are very different from traditional heat radiation and gas discharge light sources (such as incandescent lamps, high pressure sodium lamps). The current LED light source has the following advantages in lighting:

(1) Good Anti-vibration and Impact Resistance

The basic structure of an LED light source is that electroluminescent semiconductor material is placed on a lead frame and then encapsulated with epoxy around it, without a glass enclosure in the structure. There is no need to evacuate the tube or fill it with a specific gas like incandescent or fluorescent lamps. Therefore, the LED light source has good anti-vibration and shock resistance properties, which brings convenience to the production, transportation and use of the LED light source.

(2) Security and Stability

The LED light source can be driven by low voltage DC. Under normal circumstances, the power supply voltage of slim led light bar is between 6 and 24 volts, and the safety performance is good, especially suitable for use in public places. In addition, in a better external environment, the light source has less light decay than traditional light sources and has a long life. Even if it is frequently turned on and off, its service life will not be affected.

(3) Good Environmental Performance

Since no metal mercury is added to the LED light source in the production process, it will not cause mercury pollution after being discarded, and its waste can be recycled, saving resources and protecting the environment.

(4) Long Lifespan

The LED light source is called a longevity lamp, which means a lamp that never goes out. Solid cold light source, epoxy resin encapsulation, there is no loose part in the lamp body, there are no shortcomings such as easy burning of filament, thermal deposition, light decay, etc. The service life can reach 60,000 to 100,000 hours. More than 10 times longer life than traditional light sources.

2. Heat Dissipation Capability Is Important

At present, the common LED bar light fixture heat dissipation structure on the market is made of aluminum material, and then the heat is directed to the external aluminum material through the aluminum substrate of the lamp bead for heat dissipation. Therefore, the purity of this material determines whether the heat dissipation of an LED light bar can reach the standard. If the heat dissipation material is not handled properly, it will greatly affect the life of the LED light bar, and it will also affect the quality of the light effect of the product itself. Therefore, choosing a good radiator is also a point we should pay attention to.

3. Choose Quality Driving Power Supply

When we choose the LED light bar, we must pay attention to the drive power configuration of the product. Because of the relationship between the configuration of the driving power supply, the overall efficiency of product use, and the stability effect. If the drive power configuration is reasonable, it will often make the LED wall washer light and LED linear light consume less power and be stable and reliable in the process of use. Thus, it can be used for a long time.

Here we briefly describe the non-isolated drive power supply, whose characteristics are generally to achieve constant current and wide voltage, that is, the city voltage is AC100-230v universal. This is very common, but also requires low power, high efficiency, and in some cases, higher power, and has open-circuit and short-circuit protection, output overvoltage protection, and higher load capacity.At the same time, some safety designs should be adopted for the part involving the driving power supply, and the physical insulation method should be adopted to achieve absolute safety even when using a non-isolated driving power supply.Therefore, a good driving power supply is very important for LED lighting products, and choosing a suitable power supply can make better use of LEDs.

4. Knowing About Light Technical Parameters

(1) Size of the Lamp

The dimensions of your light bar are important because they determine the amount of illumination it can provide. Light bars come in different sizes, with some being longer and wider than others. Make sure to choose a size that provides adequate lighting for your specific needs. However, size is not necessarily an indicator of quality: Some manufacturers have found ways to maximize output while constraining size by using smaller LEDs or arranging them in specific patterns that provide even lighting across the entire strip.

(2) Wattage

Wattage is the amount of power consumed by the LED bar light fixture, and therefore how much brightness you get. If you want more brightness, choose a higher wattage.

(3) Lumens

Lumens are how much visible light output an LED produces; they determine how bright your LED flashing light bar will look when turned on. The higher the lumens, the brighter they'll be—but keep in mind that not all lights with high lumens will make them look equally bright!

5. Lighting Effects Need To Be Selected According to Actual Application

The lighting change effect is controlled by TTL and DMX512. The change effect of DMX512 is wider, and the selection should be determined according to actual needs. When installing, we also need to determine the number of LED light bar connections in series or in parallel according to the actual length.This can change a variety of effects, depending on your needs, choose the single color change or overall effect change.

6. Choose A Regular Brand Manufacturer

When we choose a supplier, we must look at whether the manufacturer is formal, whether the quality meets the standard, and whether the after-sales service can be. These are all factors that we need to consider. Only in this way can we be guaranteed and issues can be solved in time.

7. Conclusion

Choosing the right LED light bar for your needs can be a daunting task, but when you have all the information about different types of LED light bars and their features, it’s easier to decide which one is best for you. You should also take into account mounting options and wattage, so that you know exactly what kind of power source will be need and how much space is available where you want to install your new lights.
