The Four Best LED Flat Panel Light Fixtures
The simple fact that light emitting diodes are generally smaller than their incandescent and fluorescent predecessors allows for manufacturers of LED technology to design and implement a multitude of new shapes and forms for their latest light fixtures.

As the very fundamentals of what constitutes lighting design shifts and changes with the market viability of LEDs, it is highly likely we are going to see more and more products challenging the status quo and trying out new designs. Many of these are going to be new takes on traditional lighting fixtures, but some will probably be fresh ideas that cleverly utilize the form and function of LEDs. Regardless, it’s an exciting time to be in lighting, and here at Shine Retrofits we want to guide you through the vast catalog of lighting products available today, helping you to find the best in new LED lighting.

One of the new lines of products that is reworking the very way we think about lighting fixtures is the LED flat panel category. These modern LED flat panel light fixtures are designed to be installed in applications where you would typically use a fluorescent troffer, as well as with some new applications designed specifically around their new dimensions, which are much flatter and more streamlined than many of the traditional fixtures used commonly in the past.

In a nutshell, these LED flat panel lights are going to change a lot of things in the industry. The big difference between a flat panel and a troffer is the depth of the fixture. While a typical fluorescent troffer will be around 3-4" deep, new edge-lit flat panels are around a half inch thick, which is a big difference when it comes to lighting fixtures. As you can imagine, this opens up many new possibilities in where you can place lighting in the various spaces in your building. If you’re looking for new fixtures that will redefine your lighting design, then edge-lit LED flat panels may be just the light for you.

When making a decision between troffers and flat panels, you have to take stock of all the advantages and disadvantages that each product will offer you. That’s why we’ve put together a list of LED flat panel fixtures we think are the best on the market, helping you discern whether you want to try out the new technology or stick with the old troffer style of fixtures. First, we’ll address questions about the differences between the two types of fixtures.

Should I invest in an LED flat panel instead of an LED troffer?

Since LED flat panels can be used to replace troffer fixtures, we figured it would be a good idea to follow up last week's post about troffers with this post about LED flat panel lighting options. Flat panels should be considered for every application where you would use a traditional fluorescent troffer. For those looking for LED drop ceiling lights, they also fit into that category, as most troffers are also designed to fit snugly into the drop ceilings commonly used in most offices.

Along with some other uniquely shaped flat panels, most lighting manufacturers are producing standard 1x4, 2x2, and 2x4 flat panels so that they can be used in drop ceilings. However, that is not the only application. These LED flat panel lights can also be mounted directly to a drywall ceiling, increasing the possible areas and rooms you’ll be able to use them in. Since they can be as small as 1/2" thick, there is no need to recess them. This fact also greatly expands the diversity of installation possibilities for LED flat panel fixtures. It is possible to mount these to a wall, under a cabinet, or suspend them from the ceiling. Alternatively, if you are simply replacing lighting in a drop-ceiling, flat panels work there too.

If you are looking for the thinnest fixtures(~1/2") then you will need a model described as "Edge Lit". The other option would be "Direct Lit", a model which tends to be closer to 4" thick. Some of these models come with an option to add an emergency backup battery, so keep that in mind for your mounting location, as that can impact whether or not you want to opt for the battery or not.

So, if your lighting project is for a room that is currently using troffers, consider the new flat panel technology as a viable and generally more energy efficient option. There are over 30 flat panel products available for purchase right now on, and more are being added every week.

They have firsthand experience with these products, and know the ins and outs of what makes them great, whether that’s efficiency, light quality, ease of installation, or a host of other factors.
