Which light bulb lasts longer in practice?


Recommended Posts

I have to replace a light bulb in a staircase with a very high ceiling.

So high that it actually requires scaffolding to do this.

For years I had been using Philips Tornado Energy Saver 20W, and would literally last for about five years.

The last time I changed it, I might have used an Eve LED 11W, it first of all started to flicker when being turned on, then stopped working completely, now is working again - a mystery.

What I want to know is which one should be my preferred choice, when I do replace it please?

The 50,000 hours life is if you don't take it out of its package.

In my experience, regardless of what it says on the box, some last a long time. And some don't.

How many Thai Visa members does it take to change a light bulb?

I would stick with the LED.  They are getting more reliable these days.  Is your ceiling still higher than the extendable bulb changers and a ladder?

I didn't think many people used light bulbs now....a complete standard  LED light at Global House is just over a 100 baht if used 8 hours a day, it will last 17 years. I was looking at some of them last week....now you can just speak to them, (in Thai Of course ) Dim--Off-- On etc ...some will even change color when told........come a long way from a light bulb hasn't it.

Tearing apart a Philips lamp and then a Guangdong special at half the price shows why the Philips build and component quality is likely to deliver the longer life. In a hard to access location a well known brand might be less of a risk. 

If you can somehow get the Philips Dubai lamps you are virtually guaranteed a really really long lifespan as they significantly under run the LEDs and have good under run power supplies in them.

I moved in my house 9 years ago, and have everywhere Osram energy savings lamps. In those 9 years I have replaced very few, I think less than 5%.

 

In 2 ceiling fans I replaced them with 11W LED, first from Sylvania and later from Philips, because I needed brighter light in those rooms.

 

That was 2 years ago, and I have replaced each of them 3 times already

I was writing about the LED lights--not bulbs...... Quote"I didn't think many people used light bulbs now"..

The standard LED light in Global House that sits flat against the ceiling was 6 months ago when I brought 22 of them 110 baht each---As I wrote you can for a bit more, & get voice activated ones.

 

 

50,000 hours

Many LEDs have a rated life of up to 50,000 hours. This is approximately 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen, and 8-10 times longer than a typical CFL. Used 12 hours a day, a 50,000 bulb will last more than 11 years. Used 8 hours a day, it will last 17 years!  Bulbs.com

I think it is quite obvious from the OP that he has to replace a bulb, so what LED lights have to do with this is not clear to me.

 

Anyway, please report back in 17 years, how many you have replaced, because your lights are now only 6 months old..

 

If you look at my post history, you will find that not so long ago I started a thread about the short lifespan of LED bulbs, and there are members in that thread which told us that their LED lights, also didn't last long

There are many LEDs that are direct replacements for incandescent or CFL “bulbs” E40, E 27, E14, E12, E11, and BC fitting to name a few, they have the shape of the incandescent bulb and are all called bulbs

 

Yes and that are the ones that don't last, as I have each one replaced 3 time in 2 years, but sanuk711 made clear that he is NOT talking about LED bulbs

Cheap ones don’t last, good quality ones do. The base fitting is irrelevant. 
 

sanuk711 Is not the OP and the OP did not exclude LED bulbs
