5 Simple Steps to Choosing the Best LED Panel Light

5 Simple Steps to Choosing the Best LED Panel Light

Do you know how to choose the high quality LED panel light? Buying LED panel lights can be a challenging affair with tens of thousands of manufacturer and suppliers claiming to be the best. To simplify the task for you, our team of LED engineers has come up with this detailed LED buying guide with secret tips and ideas for flat panel lights.

A quick glance will give you the LED insights to pick top quality LED products that save power and last longer from the USA, China or anywhere in the world. Let’s start with the most important factor, namely:

Light guide plate and Driver

The quality of an LED panel light depends mainly on the light guide plate and driver. The light guide plate will decide the light transmittance and power conversion efficiency. The driver will decide the power factor and lifespan of the entire light panel. Hence, it is important to make sure that there is no compromise in the quality of both. Now that we understand the importance of both, let’s understand how to ensure best light guide plate and driver while selecting LED panel lights:

1. Selecting High Quality LED light guide plate (LGP)
Below are the real images of panel lights with Polystyrene (PS) light guide plates and panel lights with PMMA(acrylic) light guide plates after only half year of usage. PS material is popular in the US because of its low price but it turns yellow easily and gets dark spots which decrease the power conversion efficiency.

PMMA material has the advantages of anti-aging and higher light transmittance compared with PS material. The plate color and light transmittance will have little change even after several years of usage.

2. Selecting High Quality Power Supply (Driver)
To a Large extent, the lifespan of LED panel light depends on driver.In general, the driver’s life is less than that of the led panel light. The design of the driver and the material selection will affect the life of the led panel light. LaMoon engineers use the most advanced circuit program to design and develop the most stable led panel light drivers, and the power supply is easy to install and replace.

High Value Power Factor
On another side, LED light flicker is generally caused by large driver ripples. Usually a high PF value comes with flicker. It cannot be detected by human eyes but would be visible when taking pictures on a cell phone. As a low PF value drivers use a lot of energy and power, a certain PF value is required on LED drivers of higher than 10w panel lights. Due to the high cost, existing drivers with high PF value mostly have flicker.

At takejack.com, we offer panel lights with a high PF(PF>0.9) without flicker since higher the PF value, greater the utilization rate of power, which results in more energy-efficiency. In below image, the left is LED panel light selling on takejack.com and the right one is a general panel light. The difference caused by high PF is quite clear.

3. Choosing Led Panel Light With Great Heat Dissipation
Without effective heat dissipation to protect the critical components, high temperatures will have a severe effect on performance and reliability. Designing and constructing an effective heat dissipation system requires specialised skills and high quality materials. Cutting corners in this area is a sure way to produce LEDs more cheaply, but at the cost of long-term reliability. As we'll see shortly, the capacitors inside the power supply can be particularly susceptible. But for now let's find out what good and bad heat dissipation looks like in practice.

The left one in the above image shows a specifically designed LED panel light heat dissipation system, and the casing is made of high quality Ultra-thick die-cast aluminum. The generated heat is dissipated to the casing, protecting the critical internal components that will increase the lifespan and perform better.
While the right image above shows an LED Panel light that‘s widely available in the market. The heat dissipation system is virtually non-existent, and the generated heat is retained in the worst possible place – in the LED area just under the lens assembly. The material is of low quality. After just a few hours‘ use, the heat will start to compromise the longevity of the chip. The chances of this LED panel light reaching its claimed lifespan are remote.

4. Checking the Color Rendering Index (CRI).
Maximum Color rendering index is set at 100. In general, if the CRI is 80-100, this implies that the color rendering is excellent. 50-79, the color is general. Less than 50, the color is poor. We should select high value of the CRI. In CNHidee, CRI is more than 80 hence excellent color effects.

5. Checking the safety standards
There are many standards for LED lighting, such as UL, CE, FCC, RoHS, SAA, ISO 9001:2008 and more. Passing more standards means higher quality and safer, and of course more expensive. So when buying LED panel lights, it's better to know your requirement and the respective standards, and choosing the one right to you. However, some standards should be the must to you, such as CE or RoHS depends on your countries, as they are the Compulsory certification in some country and is the basic to ensure your safety. Don't just be fooled by the price. Safety should be the most important one you have to consider.

When considering the safety standards, the Safety of the Material should be also pay attention to. Since a general use of the high quality LED panel Light would be 2-5 years, it is very important to choose LED Panel lights that are made of insulation and flame retardant materials.

Last but no least, there are other factors to be consider when buying a LED panel light, such as  whether it is easy-to-install. Many LED panel lights would require good knowledge of electricity and professional operators.  That would be a big extra cost for installation or replacement when the light is not working. So if there is a LED panel light as simple as ABC would be best. Definitely it is not a dream.
