Oops...already changed to choke...

errs...not so understand....build-in choke means do not come with a "white" square things? Only a downlight with a bulb....

So your conclusion is:

Build in choke
- give instant start
- changing bulb is easy
- short lifespan

External choke
- give flicker start
- changing bulb is hard - may need to hire electrician
- long lifespan

Added on October 21, 2011, 10:51 amExternal choke why so big one but I can't see anything on the build in choke type downlight...where the choke hide?

Can let us know?

hhmm.....anyone please share how frequent the bulb burn if using built-in choke downlight? depends on luck?

Is it the age of the downlight? The reflex will get dull after sometime. Compare new 1.

they called choke as 火牛，am I right?

no 火牛 means built-in choke?

sorry, i am lack of knowledge on electronic...haha

Care to let us know what brand is the downlight and where to get ?

That can reduce the pcs of downlight instal and save the cost.

I've gone through it so I know how silly it is to put up how many? Only 6 to 8 down lights .
What's involved?

You need to get wireman to pull wires
You need to make the plaster ceiling
Then you need to cut the holes and each hole cost money to cut
Then you find out the some of the holes are in the same place as the supporting aluminum for the plaster ceiling but no choice, you have to cut them if you want your lights to look even.
Then they still don't align straight. Not easy to align square lights.
Then hire the wireman to install them
They will buzz like crazy and you need to get the plaster ceiling guy to come back and patch up those broken sides cause he cut the hole too big or too small
After all the fuss, they are not even bright. I used up 5 square holders and each has two bulbs of 18watt in my bathroom. Still not bright enough!

Hang two crystal chandelier kau tim or install lights at the edge of the plaster ceiling if you want a clean look

I bought them from Wong lighting. Where got brand wan?
My ceiling is quite high maybe that's the problem. I much prefer halogen but true that they are hot and makan more electric. But at least it's bright

If really have to use down lights I would go back to round ones. No glass. Got its own reflector. Easy to change bulb.

Expensive wor. Last year search this mag led light till HCM vietnam. Selling at RM200 for the AA battery type.

I've research LED downlights for my new place, it seems CREE have a good name http://cr6.creeledlighting.com/#/content/pages/8.html but they are very expensive! They are not sold in Malaysia, I got the price from the Hong Kong distributor it was HKD700 per light that's RM280, not practical! I've found a China made one from Shenzhen for USD25 per light using Phillips LED. That seems reasonable and it will bring about savings in the electric bill in the long run. I will pick them up when I visit HK over CNY, make a day trip to Shenzhen.

I've also seen a new shop open in Mid Valley concentrating solely on LED lighting, but most of the stuff there were selling is China made with a heavy mark up! LED is definitely the way forward!

Our local Municipal are moving towards LED as well. Those who travel along Subang Airport road and KL-Bentong will notice the streetlight has been changed to LED and they do look reliable. Maybe can find out the brand and see if they do produce household DL as well
