And I find a good quality downlight reflex much better light than cheap RM 20 downlight.

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

Comparing my new house master bedroomt (bigger room), when i only switch on 3 downlight is brighter than my current house room switch on 4 downlight.

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

Could be too, but i remember my current room never been that bright (comparing to my new house). Could be my house new downlight reflector are better too.

Good LED lights are too expensive.
By the time you cover the ROI, the technology would have been a couple generations later.

What most shops are selling are sub-quality China-made LED lights.
These are affordably expensive. Not bright enough with bad colour, and I heard that the controller circuit do breakdown.
Not worth it.

So flourescent all the way until LED really stabilizes.

There were some measurement made on good quality LED vs poor quality LED, at the same wattage of let say 7W, good one can give as high as 700 lumens while poor one may only give less than 400 lumens. Which the brightness is like 1 good LED bulb = 2 poor LED bulb.

Good to use LED is Mag torch light. Battery will last very long, and light can go far far.

this LED downlight seems nice with a lot of good review

It's made by cree but not sure if anything similar here. if yes would like to give one a test as so many good review over the net.

Thanks for the response.

It seems that there are several versions of cree lights. The one shown above is most probable LR6 variant which is on the higher side of pricing.

the one from home depot in US is the CR6 and some places are selling it for used 25 the lowest after some discount. I hope the LED price will go down at a faster rate than before.

I contacted a friend in the states which is willing to help with the purchase however the shops don't have 220v version as US is using 160v. I even checked with Cree and they said they don't have this at the moment.

I did manage to mail the CEO (unintentionally) and he said he's checking with their LED lighting product team to response but I haven't got any replies yet.

Surprisingly also one of the general manager is actually based in penang. check out the link below.

Soo Ghee Lee, vice president and general manager, Asia Pacific, comes to Cree with more than 25 years of optoelectronics experience, most recently with Avago Technologies where he was vice president and general manager for the solid-state illumination division. He will be responsible for the development of new revenue streams and extension of customer relationships in Asia Pacific. Lee’s appointment is effective January 14, 2008, and he will be based in Penang, Malaysia.

hope can get this here and also at a good price so there's high adaptation rate which will drive down the price even further .

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!

so you think its not worth buying?

Actually, there are still finalising on the international standard to classify brightness emitted from LED. I do not know what is behind the theory, it seems the current light meter used to measure brightness is not registering the correct brightness of LED, for example, say a 350lumens of a fluorescent light VS 350lumens of LED light, the LED light might look brighter to our eyes.

They should use 4500 or lower k color. I travel along that way daily very bad when medium too heavy rain. There still reason why hela light is still yellow.

so far, LED light are more for ID/decorative lights. Buildings are still depending on CFL and other gas tube to achieve acceptable lux level.
