For item 1, the PLC lamp need a separate ballast to work but ELC (item 2) come with built in ballast,

which one better? so far both are equally good in lifespan (15000hrs buring hour)if i can remember correctly, except the price for the ELC are slightly higher than PLC, but do take note that ELC downlight are not as common in market, you have to make sure that the lamp itself (minus the ballast part) are long enough to cover the whole downlight glass if not you will have dark shadow due to the ballast.(ELC ballast take up almost half the length of the lamp)

E27 i.e screw type. easier to change bulb. Downside is that E27 imposed a limit up to a certain brightness of bulb that u can use, due to the screw portion that is wasted space. If u compare with 2-pin type, the holder portion is much shorter.

Most shops only sell 2-pin type. Some shops offer service to help u modify the light to E27 holder.

Get the light with E27 socket as it comes with built in electronic ballast. PLC uses seperate magnetic ballast that uses more electricity as it generate more heat. The E27 CFL light is flicker-free as it uses electronic ballast built into it, gentle to the eyes. For the same power used, CFL will be slightly brighter too.

Do note that the CFL that comes with clear casing covering the white bulb have a slow glow start, if want instant bright start, choose those without clear casing. Cheers.
