At this time, when I take a look up at at celing, I can easily to see the difference of them.The LED panel light is at size of 600*600mm, rated power is 40W, while there are 3 pcs of 600mm tube light with rated power of 60W each, but the LED panel light is much brighter, and looks gender and soft, nice to look for eyes. And what matters is the LED panel light is really save the power, whereas save your electric bill up to 70%.
