There are now more options for LED panel lights than ever before, making it exciting yet intimidating to select the right product. We will explain the differences between edge-lit and back-lit panels below.

In a well-designed back-lit panel, each LED is equipped with its own lens, which is designed to ensure that the light from each LED overlaps with the light from its neighboring LEDs. This results in an evenly lit effect and provides some resilience in the event of a single LED failure. However, poor lens design and a low number of LEDs can lead to reduced overlap between LEDs and increase the risk of having bright and dark spots on the front of the fitting.

Higher quality backlit panels are constructed with a metal body, which is more effective at dissipating heat than the cheaper alternative of a plastic body. As LEDs generate heat, proper heat dissipation is important for extending their lifespan.

Below we show you the application examples. One features an edge-lit LED panel light, and the other showcases backlit LED panel lights. The backlit panels emit a strong downward light, as you can tell, while the edge-lit panels diffuse the light more and have greater versatility.

Edge-lit and back-lit LED panel lights are both accepted in the lighting industry, but edge-lit panels were used and mass-produced first. Back-lit panels were introduced later by manufacturers due to technological advances.

Thanks to technical advances, back-lit LED panels now use less material as the light shines directly through the diffuser. Here’s a look at the pros and cons:

If the number of LEDs used in a design is too few (generally 36 or less), then they have to be driven at a high current to produce the necessary light output. This is less efficient when compared to designs that use more LEDs, as LEDs perform most efficiently with low drive currents. High currents generate more heat, shorten the lifespan of the LEDs, and hasten the lumen depreciation.

As a rule of thumb, if you are looking for maximum savings and efficiency, it is advisable to consider back-lit panels first. However, if the thickness and design of the panel are more important, then it’s better to consider edge-lit panels first.

Now that you understand the differences between backlit and edge-lit options, you can pick the LED panel lights best for your offices, retail stores, or healthcare facilities, and other commercial settings.

The market now accepts backlit panels as readily as edge-lit panels. Here at YOURLITE we have had both designs in our product range, but we have decided that backlit is marginally better.

It is worth noting that the performance differences between edge-lit and back-lit configurations are getting narrower. When placed side by side, they may look almost identical. Some back-lit panels provide excellent light distribution without any noticeable bright spots. On the other hand, edge-lit panels are becoming more efficient and performing better.

A back-lit LED panel, also known as direct-lit panel, is made up of an array of LEDs arranged on a horizontal plate. The LEDs shine vertically down through a diffuser to illuminate a space.

Are the lenses firmly fixed in position? It remains to be seen if the lenses are securely attached. The concern is that the heat produced by the LEDs, along with subpar adhesive application, may lead to the lenses detaching. If this happens, the light distribution will be uneven, and there may even be some glare.

The main difference between edge-lit and backlit panel lights is the location of the LEDs and how light disperses from each fixture. But what does that mean for you? Let’s dig a little deeper.

An edge-lit LED panel consists of a series of LEDs fixed to the frame or circumference of the panel. The LEDs shine horizontally into a light-guide plate (LGP), which directs the light downwards through a diffuser into the space below. Edge-lit panels are also sometimes referred to as side-lit panels.

In an attempt to lower the cost of edge-lit panels, some manufacturers have incorporated cheaper materials and assembly processes that have negatively impacted the quality of the panels, primarily on the Light Guide Plate (LGP). Some manufacturers have started using Polystyrene (PS) LGPs, but they tend to yellow with age if UV stabilizers are not added, resulting in the panel becoming dull in the center while the periphery remains bright. Furthermore, PS has a lower light transmission percentage than PMMA.

Edge-lit LED flat panels were the first to be mass-produced and still have a slight edge in the market, especially when there is aesthetic preference. Here’s a look at the pros and cons:

Manufacturers have the option to save money by integrating the driver into the body of a device, also known as a built-in driver. However, this approach has several drawbacks. Firstly, in case of any issues with the driver, it cannot be replaced. Secondly, there will be no dimming or emergency options available, making the device inflexible.

It is possible to make relatively cheap backlit panels as they do not have LGP. Some manufacturers promote them as a low-cost option.

If you’re considering upgrading your suspended ceiling lighting to LED panel lights but feeling overwhelmed by the options, you’re not alone. Making the switch to LED lighting is a fantastic step toward energy efficiency! However, when it comes to LED panel lights, a crucial decision lies ahead: edge-lit panels or backlit panels. In this blog, we’ll explain the difference between the two and go over the pros and cons of each option.

LED panel lights have become a popular choice for ceiling lighting due to their durability, reliable quality, versatility and low cost. They are frequently used as replacements in retrofit projects for troffers of all sizes, including 1×4, 2×2, or 2×4. LED panel lights are also often preferred for new construction projects because they are thin yet sturdy. These flat panels can be mounted or suspended from the ceiling with cables and are just half an inch thick.
