alot of times is the driver problem. but they will just change you another with the same problem. china brand driver is not "truthful". we also sell these lights and we also face same problems with drivers, that is why now we dun sell much nowadays. respectable brands are hard to come by nowadays, with prices coming down sharply. alot are compromised with bad quality

if you guys wish to change to led bulbs, we have the bulb type(attached picture) from LG Korea(original). 2yr warranty(limited), 7.5w, and bright too. what's more, it's UNBREAKABLE! tried it many times.... RM65 each

This LG(Korea) we got is quite an amazing product. The heatsink part is made of magnesium alloy, thus they claim to be very good heat dissipation. Also they guarantee 2 yrs warranty! That's why we grab this deal. Also the importer is supplying to the local govt project, now already used >1k pcs. Balance, we try to market for them.
The LEd is new technology, COB - chip on board. Attached some useful info, hope you guys can enjoy it.

Osram has a quite similar product(but 1yr warranty) which we will be selling soon. Cheaper, @Rm55. Will get more info and upload.

this product shown needs a driver to light it. Normally, the one with the inbuilt driver is longer, like in this picture, but this is screw head. See the part with the white portion, this is where the driver is.

There are so many variants nowadays, but not a single one can claim they are reliable. Prices can range from RM10-RM20. frankly, these LED can beat the halogen on low power consumption, but the halogen is on its own when it comes to producing a perfect ambience lighting. A lot of designers vouch for this, that is why they always recommend halogen. But too bad, they are energy guzzlers .

for chandelier, you should consider using these LEDs, still a bit pricy @RM28, but only 3w, compared to the usual incandescent with a min of 25W. comes in white light too. But, these LEDs are not for illumination purpose if you think of lighting up an area. Unless you have many bulbs, they are not bright enough.

will get you more details, all china made. supplier warranty 6mths, but 3w bulbs like these normally not so much problem compared to the LED downlights, with lots of problems with the driver

YET & JSE are china oem products. these are sold very cheap in lighting shops like Top Ten, Avalon, etc. we are also electrical shop, but we normally don't recommend these in our projects. YET have many variants, let me know what is the model, and I can ask whether can reduce further the price. I guess the JSE bulbs they give you are the screw head bulbs, which at those prices, quality is compromised. if you want lasting bulbs, you should use PLC tubes with external ballast. but the total price is much more.

got price for YET, fitting alone RM8.00, normal bulb RM4.50 to RM5.50. The price you get RM13.50/set is very good. Try asking if you can just buy the fitting and then fit with PLC tubes and ballast. the YET downlight can also use PLC tubes, just ask them to change to PLC holder. Philips PLC18W tube costs RM6.00/pc and good ballast cost RM5.50 (Sova brand). The lighting shop can give very good price coz they order in bulk, and also they always fight price among themselves

depends on the type of designs you like. don't go for too fanciful ones, the designs may not tahan lama white downlights are easiest on the eyes, especially low ceiling situation. get bulbs where there are ready replacements, like energy savers. LEDs are getting popular becos of the low power consumption, but good ones are too expensive. cheaper versions don't last, esp the driver(transformer).

those downlights u get in lighting shops that looks like stainless steel are not real stainless steel. there are very very few that is really stainless steel. SS ones are very expensive, so hardly any importers. what shape you looking for? round, square, patterns?

head down to any of the light shops, u get many varieties there, but chances r you won't get high end ones, just normal ones. but they will do, just choose those with plain white frames, will match your interior better, rather than those with all the frills. but do keep note that 4" will better fit 1 bulb, coz if fit 2, than lifespan of bulb shorten caused by heat. 1 bulb will not be bright enuf, so need to have more lights. to hv longer lasting bulbs, use PLC with ballast. use good quality ballast like Sova, Solex or Luxram. normal brands will hum after some time. but if u 1 easy fixing, then use screw bulbs.

they prices are sure cheap, however, assuming that the LEDs are really what they claimed to be. Most are shipped from China, so you can never be sure of the quality as in Ebay, the company names are not stated. Not like in Alibaba, where the company selling the products are known. You can check this link for some info - http://www.alibaba.com/trade/search?Search...roduct_en&fsb=y

T4 tubes are hard to find coz there is no standard length from all the manufacturers. would advise to change to T5, as this is easily available, and all the tubes are of standard length, no matter which brands.
Do you have a lot of T4 to replace?

Added on March 24, 2012, 7:47 pmdoes Cree have downlights? As far as I know, they only manufacture chips, and they leave the full products to other OEMs. yup, they have the best LED chips around, and many China lamps manufacturers use their chips. but dun know if they really use Cree or not :-(. do you have the US link for Cree where they manufacture downlights?

at the moment, there is no guarantee for LED. how long they can last is anyone's guess. Even the Osram LED bulb, it is written 3years guarantee, but when you check the website, it says only warranty in Europe. why? Europe's current is more stable, here, variance can be big. so LED can rosak.

LED now have wide range in prices. Cheap ones may not necessary rosak faster, but the lumens drop, i.e. gets dimmer as times flies. Find out more info in the net, then u can get a clearer picture.

t4 and t5 flourescent tubes are differentiated by the diameter - t4=1/2", t5=5/8". The normal T8 flourescent tubes which we normally use is 1". See this site :http://en.wikipedia.org/wiki/Fluorescent-lamp_formats.
Nowadays, a lot of manufacturers are switching to T5 flourescent lamps for more energy efficiency(completes with electronic ballast fitting). T4 is being phased out coz there is no standard length, thus every manufacturers has their own specs. T5 lamps follows a certain specs, thus replacement is easy, just like the good ol' T8 .
Now, everyone is switching to T5 LED, but we have to note that this is still at a premature stage, as there is no concrete tests that the LED is outright better in terms of efficiency and cost-savings than the T5 flourescent. Just have to remember that LED is high investment costs(for good brands), but whether the ROI is as good as the manufacturer claims,
Cheers...

nice....but not sure if Philips Malaysia has this, haven't heard of the Philips guys mentioning about this product. Must be a European specs..

I've actually tested out with an Osram T5 28W, side-by-side, same colour temperature(3000K)...but not much brighter than what was claimed....I didn't test with a lux meter though, but from bare eyes, looks the same.

the screw head should be E27 type, as normally the wall light comes with that kind of lampholder size. but you should consider the spiral cfl, coz the up-down lamp fitting may not have much space for the normal cfl. since you mentioned the original is only the incandescent bulb, so you only have about roughly 3" of space.

this type comes in 5/8/12w. but I think you can use the 8w. here's the link which you can read some info:

available in most lighting shops, or electrical shops.

Sylvania is a UK brand, but made in China, so still ok. What kind of YET downlight? but T5 if china brand, a bit more than normal...
