Let me start first.

1)Sylvania -E27 MINI-lynx economy 15w - rm 7 HOL(house of lighting)
2)Midea -E27 SaverStar 12W - RM10 (top10)..
3)NSB -12W LED-DL -RM27
4)SMD(Samsung chip) - 12w LED-DL -RM43.

1) Laniber - 12W - RM40 (Avalon)
2) Laniber - 18W - RM50 (Avalon)

Good? Not cheap too

Without the quality, what the use with such price?

The cost of manufacturing the LED light is very cheap. Driver design is not something new. However the price is high. With China bulbs in the market, force price down. So, if you just care about light, just go with China brand. I used one from Mr. DIY and it OK so far. However, if you are looking into the one with good CRI, then the price is not cheap.

The LED color is just like other pigment based product such as tiles, there is always slight color variation. Even when ordering the LED, the color is guaranteed in in a range of color temperature, not very specific. Manufacturer has to do mix and match to get combination of LEDs that would give the right color.

A normal CFL bulb can last about 1.5-2yrs with a price of RM19 for a 23w which produce 1500lumens.

If the LED can't match such an old tech, what is the point are we buying? With such a price.

Are we forget what is quality mean to us?

LED is dropping price but CFL is also dropping price. LED can last much longer than CFL, A far as I know the LED require less power to produce the same lumen as CFL. CFLs are sensitive to frequent on/off cycling. Their rated lifetimes of 10,000 hours are reduced in applications where the light is switched on and off very often. CFL takes a while to go to full brightness.

For me, even if the disadvantage of LED is price, but this is is negated by its lifetime. I'm slowly phasing in LED bulb when replacement need. So, my observation is still immature

CFL will last longer, and lumens/watt is still better on cfl. For led with higher lumens/watt than cfl will be more expensive.

What you tell me is just a theory. And by their brochure? How long have you using the same LED bulb ? Average how many hr? What is the lumens before and after?

You need to proof it. Not by the box telling you that is can last 40k hr. A 40k hr can last me for 4.5yrs if I ON it for 24hr. But the china LED even can't warranty me for over 1yrs.

LED use less watt. But also produce less lumens. For the capalang china brand. You even cannot find what is the lumens/watt from their product infor. What they only can tell you is watt and watt. That doesn't tell me anything about the brightness.

CFL is kill by the heat. A long hr with the high watt can heat up the electronic inside the bulb. Frequent ON/OFF doesn't kill it. Unless the switch you ON/OFF is producing spark.

LED bulb too. The main killer is the heat. And the main culprit is the capacity.

Try get 1 of this. New exciting bulb from philip. 14w produce 100w. 1500lumens. Brought 6pcs and still testing it in US.

I'm not just looking at the box. Yes, previously the LED is not that good but now it is improving a lot. I searched through 3rd party articles, not manufacturer's itself.

Did you notice the black spot near the electrode of the CFL. This is because high voltage at start-up sends the lamp’s mercury ions hurtling toward the starting electrode, which can destroy the electrode’s coating over time. There are research papers that study how long the bulb last with relation on how frequent the florescent light is switch on/off. This is one of the reason why the CFL lamp did not last as long as the life indicated n the box. For me lifetime on the box is indication only. Unless everyone follow same measurement method, it is not reliable comparison. This is also same for LED lamp. I don't trust what is printed there.

CFL and LED is killed by heat. I agree on this. I've been using LED for about a year now and I have both CFL and LED bulbs in use.

You need to test longer. In your case, did the bulb payback your money for about a yrs? Compare to CFL. (the only bulb you can compare $/day use) Did the LED bulb lumens match the CFL? What is the lumens/watt for the LED?

You get a china LED for a RM40. That is 2.5x the price of the cfl. How long can you test and confident to tell us this LED is good?

I use Hitachi and Panasonic CFL which wrote 8k of lifetime on the box. That is average lifetime I get from the CFL bulb I use. No bullshit. Specially Hitachi old stock CFL bulb which is made in jpn. I sapu it if I saw it on the rack shop.

My car porch CFL Panasonic bulb just blow out last week. That last about 1.5yrs. 8000hr/12hr/365 =1.8yrs. That is 0.03sen/day.

Yup saw your image before. There are improving, and to get the price down to matchable with CFL brightness will take sometime.

Lifetime shown on the box is on test lab, and we do not know what are the condition and environment of the test lab. The lifespan hours maybe running nonstop 24x7, and stable voltage, while in real life the frequency of On-Off, input voltage condition, surrounding heat will have impact the lifetime of the bulbs, be it LED, CFL, or incandescent.

No doubt you have to test longer. I do not have lux meter to measure actual brightness to be more specific but now I'm comparing my LED and CFL. The LED (6x8W) I light up everyday seem to be brighter than my CFL which I rarely used in the same hall (6x8W), but that probably just my perception.

At the end of life cycle the florescent tube will require a bit more power to start ionizing the gas the tube and light up. I've observed this when repairing the electronic "ballast". One that has not been used for more than a year just failed to light up. I suspect everything but the tube. Unfortunately the tube just killed the driver. I was also surprised. Gas leak? It was either Toshiba or Philips, can't remember

In my home, the most last is the flurosent light. I still have flurosent light working since 17yrs ago. It just freaking don't want to spoil.

The 2nd last is the PLC light which last more than 5yrs. The 3rd last is the LED DL overtake the CFL just recently and still counting.

I started phasing out E27 CFL slowly with LEDs too since few years ago when the price of Phillips in Giant slashed 40% to around RM2x~.
The Philips and Osram still serving well till now at the kitchen and dining area.
I also have few Mr DIY 5w E27 LEDs serving at the hall and stairway area for more than a year now. The LED at the stairway is switched on overnight everyday. From my naked eyes, I find the 5w LED is brighter than the 5w CFL when comparing it side by side.
So far, there were 2 LEDs failed after one year that is Sylvania and EcoLife.
After few years of experimenting with LED bulbs, I think the China made LEDs is getting better, brighter and cheaper. I will continue to replace the retired CFL with LED bulbs.

Haha, your are right, the 36w T8 flourosent is damn lasting. The ballast already emitting annoying sound and I was hoping it spoil faster in order to replace it with T5 LED. End up I can not tahan the annoying sound and replace it with a LED tube anyway.

What I observe in the western market and their consumer usage, the 100w is not a favour. Instead 60w warm white are more popular and cheaper. They don't like bright light for home. Not like Asian people. Instead 100w like this is more for sturdy lamp.

Another LED in Thailand market. If you see properly the packaging, they state the Watt, Lumens, price, Dimension etc. Same as the western Philip. Their consumer is more informative compare our local.

Now go all the way to Thailand shopping Should spend time at their outlet lah.
