LED panel lights are somewhat different than LED down lights, and they’re now commonly used for interior decoration lighting purpose. All its advantages and disadvantages are listed here to know more about the new lighting option in details.

You may hear about LED Lights, but LED Panel Lights… sounds new and something different. Of course, it is! LED technology becomes popular now and has been used widely because of its amazing power saving, but LED panel lights that use somewhat different technology are fairly new to the market. In spite of this, it is notably gaining ground for its sleek look, innovative features as well as design. This modern type of lighting fixture is designed to replace usual fluorescent ceiling lights. Also, it would be one of the best lighting options for indoor settings considering its modern design that gives better illumination conditions, flexibility in design, efficient light quality, use of great material, extremely long usability span, highly durable, different color options, and capability to suit multiple applications, etc. With all these strong points, you can say that LED Panel Lights will be undoubtedly, the way of the future. No doubt LED Panel Lights come with some drawbacks, but considering its great advantages, disadvantages may be neglected. Checkout both advantages and disadvantages of LED Panel Lights here, and choice is yours!

Advantages of LED Panel Lights:

Flexibility in Design:

LED panel lights are designed in such a way that provides better lighting conditions. Using the latest in LED technology, LED panel lights are made of a lightweight aluminum frames and diffuser. The aluminum frame is one of the more important led panel light parts, because it is designed to put off light leakage and dissipate heat. First layer holds LEDs, second plate guide light and third is for a diffuser. The diffuser is placed at front and most visible part. Its function is to distribute light uniformly across the surface. Also, there is a reflector plate right at the back of the LED guide plate. And its solid backing helps giving amazing effect on the lighting fixture’s overall look.

Best of all, its design is very flexible. As LED is a point-like light source, LED lighting designers make use of the combination of point, line, and plan to design panel lights and keeping in mind customer’s requirement, they can design LED panels in a variety of shapes and with different numbers of light source and different particles of light.

Ultra Slim, good heat dissipation:

LED panel light is super thin, looks simple but stylish. Here its side-lighting design and aluminum frame guarantee good heat dissipation. Also being equipped with a heat sink system, LED panel lights ensure high level of safety.

Best Light Quality:

When it comes to the quality of the light, as optical material – LED guide plate is used in making LED to offer bright and uniform lighting on connecting to a power supply. Here guide plate and diffuser work jointly to create equally distributed, wide and soft lighting. What’s more, its latest technology allows instant starts without any humming, flickering or RF interference.

Use best material for high brightness:

It makes use of Aluminum, which is the best material for the frame, also used for the back cover. We know that LEDs itself are generally made from aluminum, arsenide and gallium. Here LED panel light adopts a homogeneous light reflective panel as well as sealed design along with high efficiency light guide plate & aluminum alloy material, and all these together make the output light more effective and glowing. Also, impurities are added to create free electrons as well as to increase the semiconductor material’s conductivity.

Color options for the light:

Interesting part is that such impurities could also decide the color of the light. This way, the favorite color lighting could be getting without the use of a filter. LED lights can also generate white light.

Long life:

LED theory life is up to 100000 hours, calculating as 8 hours a day, its theoretical life will be 27 years. And theoretical life of the LED panel lights even more than 10 million hours. As per the Department of Energy, electricity demand for lighting in the U.S. could be reduced by one-third by 2027 with a quick adoption of LED light panel, eliminating the need for 40 new power plants.

Shock-resistant:

LED light source of the panel is made from a high hardness resin instead of tungsten wire glass, that isn’t easily damaged. So the vibration force is comparatively high. Besides, it has good temperature flexibility.

Environmental friendly

LED panel light is also a green lighting technology. It has no mercury, no radiation; also the manufacturing process makes almost no pollution. All the material used can be recycled, and these recyclable characteristics are very essential for the sustainable development economic and social development.

Amazing control ability:

LED panel lights can be controlled through a variety of dynamic programs, as it can be dimmed in brightness and CCT via an external controller, like PWM remote controller, triac dimmer or DMX512.

Light Adjustment:

The light color of LED panel lights can be adjusted according to the different needs or circumstances. It provides eye-friendly soft light that can protect eyesight with no radiation and glare or unpleasant light. Here all colors are moderate accordingly people can look directly at the light without dazzling.

Customizability:

The principal advantage of LED panel lights is their customizability. Because of their thinness and the way that the LEDs are fixed into the panel itself, they can be shaped into almost any type preferred. These allow them to be used for applications where the use of traditional incandescent lighting would be difficult or impossible, like backlighting for molded bar tops.

Work well in area with unstable electricity supply of voltage:

No doubt that conventional LED lights are popular, but one of its serious drawback is that a single broken LED can have a considerable adverse influence on others nearby. With LED panels, this problem is much reduced due to a carefully thought out circuit design. Thus, panel lighting would be best option for the area where an electricity supply of stable voltage cannot be guaranteed. Using LED panels, there is no danger of overheating, unlike with incandescent bulbs, as LEDs have no thermal effect.

Ideal for installation where maintenance is difficult

The acrylic used for light panels is resistant to shocking and to many corrosive chemicals; also it can withstand hot and cold temperatures and humidity levels. This durability makes LED light panels perfect for installation in places where maintenance is not easy, for example hard-to-reach areas which might require closing of a building for full replacement to be carried out. Here using LED light panels will lead to a drop in total costs.

Disadvantages of LED Panel Lights:

Big Fixture:

To spread light uniformly all Panel light are made with high dimension fixture. As you increase output watt you will have to choose bigger and bigger.

Lower Light output:

As mentioned above, LED guide plate and diffuser are used in making LED panel lights to create equally distributed, wide and soft lighting. Here problem is that diffuser blocks the light output to spread/distribute the light evenly, in result we can get only 60-70% light output while we can get up to 95% light output from LED light bulbs.

Not Effective Power Saver:

Due to diffuser to spread light intensity uniformly, Panel lights slightly gives lower output as compared with the same watt of other spot LED down lights. To get the adequate light intensity, you might have to increase wattage that ultimately higher the cost of electricity…it means LED panel lights are not as power saver as LED Bulbs or LED down lights. For e.g. 8 watt LED Lamp is giving same light output is 12Watt LED Panel light. Now you can easily calculate and compare burning electricity cost based on usage.
