Two Tips On Selecting LED Panel Lights

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.

Let's understand how to ensure best light guide plate and driver while selecting LED panel lights:

Selecting LED light guide plate - Below are the real images of panel lights with PS light guide plates and panel lights with PMMA 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.

Selecting LED light panel driver – 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.
