I have been wondering for a long time if the PLC downlights in my house that use CFL (compact fluorescence) bulbs can be replaced with LED light bulb without much modification. Today, I've finally found the answer.
One of my PLC downlights is faulty and I need to replace its 18W CFL bulb. While searching for its replacement at the shop, I found this...
Yes, it is the PLC light bulb with 2-pin leg that fit with the fixture of my downlight. Instead of CFL tubes, this product is using LED as its lighting source.
So, this is exactly the LED solution that I've been searching for years. Even better, this kind of LED light bulb fit exactly to the existing PLC fixture, and totally no modification is needed.
This LED light bulb is more environmental friendly than the CFL, as it contains no mercury. It also claims to have longer lifespan than CFL, and consume less electricity to obtain the same amount of lumen output. In addition, LED light generates much less heat than CFL. It is also said that LED light does not attract insects, which is a desirable feature. However, this LED bulb is a little bit more expensive than its CFL counterparts.
I have purchased one to replace the faulty CFL bulb. See it in action below:
Finally, I've found the solution to change my PLC based downlights at my house to LED type.
I have been gradually changing the CFL bulbs with E27 base to LED type, as LED light with E27 base has been around for a few years.
Eventually, most if not all the lamps at my house will be LED based, when the CFLs are gradually replaced after they have reached their end of life.
