For personal point of view, now LED technology is more mature than before and more slim so that do not have to build a very thick false ceiling as you know for normal HDB house, ceiling just 2.6m~2.8m high. Compare with LED and PLC, everyone say that LED driver is very easy to spoit and no one talk about the disadvantage of PLC. PLC downlight is thicker than LED downlight and life span is almost 10 times shorter than LED downlight. So every time that you repair PLC, you need time and money to sourcing PLC and ballast. You have to be aware of these kind of invisible cost. PLC downlight cost 2 times electricity than LED with the same brightness. If you can afford the initial cost, LED downlight is much better than PLC downlight. Best Regard
