Philips came out with a E14 base 3W LED bulb, 2700K/"827". White base. Compared to incandescent it would be 15W. Saw it at BEST Denki.
White exposed base, hence for classic chandeliers it would be suitable for crystal type or white type. Black would look weird. Or those hambuger contemporary type with acrylic coverings. You need these point source to bring out the sparkle with any type of crystals in any type of chandeliers. (candle tip CFL won't do that)

You may have seen similar 1-2W ones from OEM china ones at Comex/Sitex. S$23 or so. The Philips is S$29.90. So I guess "ok".
Prices will come down in the future, but we are not in Taiwan/China whereby its LED country there, so OEM cheap stuff not easy to come by.

http://www.ecat.lighting.philips.com/l/catalog/catalog.jsp?userLanguage=en&userCountry=aa&catalogType=LP_PROF_ATG&_dyncharset=UTF-8&categoryid=LP_CF_NOVAL_EU_FA_AA_LP_PROF_ATG&productid=929000186702_EU_AA_LP_PROF_ATG&title=Novallure D 3W E14 2700K 230V B35 CL&ctn=929000186702_EU

The base of the bulb houses a 3W emitter and shines upwards to hit the crystal which reflects and refracts 360 deg omni to emulate a point source.

They have 3W, 9W frosted ones, but not sure why they wannat do that. CFL do better for a much cheaper price, 10,000hrs is enough for most anyway. Smile And modern CFL switch on already 80-90% full brightness, and no flicker start-up.

3W is good for low-intensity or mood light, used in multiples in a chandelier. But what we need is 5-10W emitters. Main issue is heat disspation at the LED junction.

I've done a calculation for wattage power savings and incan bulb replacement, approx 5-6 years can break even, 4hrs a day. With this mainly I guess you won't feel guilty to leave the light on, as opposed to incandescent and to a certain extent halogen. It would be more if your room is air-con (the heat emitted need to be taken out of the room by the air-con). "Psychological". Seriously, what good is a nice chandelier with incan/halogen that is used only during house warming, christmas, new year and CNY? Smile

Do note that the LED's CRI is 80. CRI of halogen (without the blue tint, using neodymium coating) is 100 or very near that, ie basically perfect.

You mean you are going to change your 50W halogen of those MR16 or GU 5.3 or whatever reflector to LED? Do note that these are running on 12V. There are 240V ones but you must carefully note whether your luminare's receptacle can accept or not, even though they are of the same number.

If in doubt, just DIY whack in the strips. Cheap and easy. Twisted Evil And actually better than those downlights, coz they have a glass (transparent or frosted), which gives you a slight greenish tint. My 2 toilets have the strips, wife and I don't even turn the PLL/CFL downlights on. Razz (use the water heater switches)



Thinking of running some strips vertically down both sides of the vanity cab in the MBR. Nowadays the 2700K LEDs are really nice.

The Philips is S$29.90 per pc. 3W.

http://www.aliexpress.com/product-gs/431564844-e14-led-candle-lights-240v-with-COB-chip-3W-AC85-265V-E14-E27-base-optional-2year-wholesalers.html

I purchased 3 of these 9W total - just nice for a romantic mood from the crystal chandelier. The crystals need point sources of light as for my model the crystal chains are hanging below the E14 base. Put CFL and no sparkle. Incandescent will suck a lot.

I paid usd7.01 for each, but it has raised price already. I have calculated, 3W gives you at least 15W of incandescent light, from the electricty savings with 4 hrs usage each night, 4 years will breakeven the cost of the light + shipping. Haven't even factored in savings from the less heat generated for the air-con to cool even....esp if you are the type who switches on the air-con frequently.

But the thing is, now I can freely switch on the light and use it with a clear conscience. Last time is - "try not to use, $$$ wise and afraid of too big carbon footprint"....ya know the conscience thingy?

Got 5W version, but the base is quite big. This 3W version is very slim, definitely ok for all E14 based chandeliers.

5W E14 LED candle.

http://www.aliexpress.com/fm-store/105303/210897893-402670623/led-candle-light-bulb-E14-1x5W-400lm-led-candle-BULB-Free-Shipping.html

It is like the Philips 3W LED candle design....the center emitter hits the central crystal and then reflects/refracts light 360 deg, thus emulating a central point source light.

The gold colour heatsink may not be suitable for those open classic-type chandeliers. But for those modern chandeliers esp closed ones, shd be alright. 3W version has a silver heatsink though.

I got the frosted glass 3.5W 210lm candle for chandeliers last year for about $5 USD each from Ebay but not that lasting I have " blown " one for the bulb maybe is a good time to replace all to 5W clear glass

Can try, how long did the circuit take to blow?

There is a HK Osram one.... 3W. But buy in lots of 10.
Can't find it now though....quite difficult to search in aliexpress. Play with free shipping and other stuff....easier to get lowest price (bo hua to pay EMS for small/cheaper shipments) and to your requirements.

Sian, I could have saved about $800 for all the strips and my LED MR16s.
Esp for those buy from interior designer's recommended light shop, kena chopped 4X the price. Laughing
Oh well...nvm lah...live and let live and enjoy......don't know what will happen in the future (since Mar 11 tsunami).

It takes about 10month for it to blown.
Local ID, lighting shop sure chop that why almost all my LED lighting are shipped from oversea or I brought it from HK last year. Ex an 4W MR16 cost around $5 USD oversea but local shop selling 3W MR16 for more than $19 - is the cheapest I can find locally.

Yeah man, that is where I got the 4X figure from. Very Happy

The heavy duty stuff, and those big stuff with a design element in it (hence need to go down and feel the REAL THING), you still need to go down to Balestier or Geylang Jalan Besar, Bukit Merah to check it out. Quite a few are not so expensive, coz lower rental + surface shipment.

But for generic ones, just buy from picture lah.....what is there to "appreciate in true form". Laughing

I think nowadays it is 10-15% worse, with the higher rental and just pure profiteering, compared to 1.5 years ago. (fuel cost would impact all the same way)

Heart pain man.... I got the same product for my display cab.

http://www.aliexpress.com/product-fm/313672028-Hi-Power-Energy-Saving-9W-LED-Downlight-wholesalers.html


Somemore come as UPS Express, 2 days sure arrive after order from China. Power supply you also can buy from aliexpress, cheap like crazy.....12V 10A got more than enough juice for 6pcs. Order extra since everything so cheap, better than any warranty (no stock in future coz stopped production, see how they warranty).


The T5 I got also not cheap since its ID (don't know what got into me). Think I paid about 25 bucks for a 4-footer....bleah.
Also did not plan properly, go run double run for different colour temperature. Now got adjustable colour temp LED strip. Not enough power, just plug in 2 or 3 runs....so cheap.

Savings from LED technology and all T5 (not only limited to the coves, but under cab/console lighting) I think over 2k liao. Embarassed

So far my LEDs, all no issue no dead SMDs. Only once the PSU (adapter type) got issue, just change...easy.

Lesson learnt for future house. Razz

The LED emitter could be Episar, Edison, or high quality Cree, COB etc.... Or could be no brand generic MIC. : )
Either the LED blew due to manufacturing defects or driver components blew.

Due to high cost of LEDs, I think most important is still to have some warranty coverage when buying.
