Ultra thin slim backlit flat panel LED Light 2×2
This is the 2026 latest new LED panel lights, with an ultra-thin slim backlit design, the height is only 20mm, instead of the old type backlit LED panel lights, which were 31mm in height. The package volume will be much less to save shipping costs. And it is with a top brand LED driver such as LiFud/Eagleries/Philips/Osram, etc. Available to do dimmable LED panel lights. Widely used for commercial lighting for offices, schools, meeting rooms, hospitals, etc.
GRNLED offers the best price in the market.

Q: How many watts is a 600×600 LED panel?
A: The standard watts for a 600×600 LED panel are 40W and 48W. But 32W, 40W, and 60W are commonly used too.
Q: What is the size of a 600×600 LED panel?
600×600 LED panel lights are called 2×2 LED panel lights too. The actual size used in different countries is a little different.
The actual size of American LED panel light: 603x603cm
Actual size of LED panel lights in Germany: 620x620cm
Actual size of Korean LED panel: 640x640cm
The actual size of LED panels in other countries: is 595x595cm, because LED panels are used most in other countries, and the Chinese panel lights size is 595x595cm too, so it is also called 600×600 for convenience
Q: What is a backlit LED panel?
A: LED chips of LED-backlit panel light emit light through lens scattering and back cover reflection from the lighting surface of the luminaire. You can see the lighting principle from the picture:
The advantages of back-lit panel lights are relatively simple technology and process. They benefit from semi-automated production lines, which result in lower labor costs. They can achieve sufficient brightness and high light efficiency, up to 135lm/w. They generally do not get yellow, and they are more cost-effective compared to edge-lit panel lights.
However, their disadvantage lies in the relatively thicker lamp body, (8-12mm), which may be less sophisticated than edge-lit ultra-thin panel lights. Additionally, the packaging volume and shipping costs may increase. Due to their hollow structure, they have higher transportation requirements compared to edge-lit panel lights.
Q: What is the main disadvantage of the LED backlit panel?
A: All LED panel lights only can be used for suspended ceilings. So I think this is the main disadvantage.
Q: What is the main advantage of the LED backlit panel?
A: Cheap price and uniform low-glare illumination are the top advantages for backlit panels compared with other lighting fixtures.
