Good evening, ladies and gentlemen.

I think not. Why? It is a very warm and soft light.

If you are interested, why I think it is worth the huge amount of credits money, let me explain a longer story:

It all started on 13th August 2014, when my grand catched an apoplex, while being on phone with my mother. My grandma got help from the doctors only after 10 minutes, so she survived, but now she cannot live in her rooms any longer and needs to live in a retirement home.
Because of that, I inherit two >60 years old lamps.

The smaller one:

The large one:

View from the table to the ceiling:

That are photos from ~ 2 months ago, before I restaurated it. Of course the angles of the arms are 72 degrees now, also I installed new cables into it.

Between August and the present, I stumbled randomly on wikipedia, and read the history of Edison and the first light bulbs, which were good enough for more than only few hours. Very interesting was a link to the "Centennial Light", which proof, that it is generally possible to run a light bulb for very much more than only ~1000 hours.
I learned a lot about the correlation between the voltage and the lifetime of light bulbs. In short: If you send +20% voltage to the lamp, its lifetime will loose 95%, if you lower the voltage ~ 25%, the lifetime of the light bulb will increase for factor 100 or more.
Same goes for carbon filament lamps, which are only a little bit more old-school than the normal light bulbs. Carbon filament lamps have a very bad energy efficiency, much less than a "normal" light bulb made of tungsten.

After reading that much, an idea came into my mind: A lower voltage combined with carbon filament lamps - those make a warm, yellow/orange light. My plan is to increase the lifetime of such bulbs, perhaps for the next 50 years.

Finally I ordered 7 of them last friday, and today they became delivered. I payed 28€ per piece, and it is worth it.

First light (in the small lamp):

Perhaps I will add some photos, when the large lamp is already finished and stuufed with that carbon bulbs too.

But finally, what do you think? Would it be worth it for you too? Let me know!

Yours,

~Cody

That's a nice shiny new toy you got there.
Sooo... where do you plan to instal them?

ProwlerPC · 12-02-2014, 07:22 AM,

Well as long as the filament lasts a long time it'll be worth it. Light bulbs have a long history of being the best example of planned obsolescence (google it for the kids that don't know this). There was a very brief period before this planned obsolescence started and some bulbs out there from those days still continue to light up the room nearly 100 yrs after being turned on and never turned off. There's a famous one in a fire dept building in America somewhere from those days. So yeah, I'd pay big $$$ for any light bulb that I'd never have to replace ever again.

In my living room. I may add a photo, when all is finished.

You may find that the light output is not sufficient as the bulb ages and you do too!
What you set up as "just right" now will not be then. Look at the reduction in output for the centennial bulb.

In EU those are not light bulbs.

Those are heat bulbs.

Its worth the investment. Im fairly sure that those last quite long and even if not, you dont just put ugly energy savers into lamps like this, thats ruining the style.

Mímir · 12-02-2014, 07:18 PM,

Nice investment.

I don't know if you watched 'The Light Bulb Conspiracy' a few years back regarding the longevity of lightbulbs among other things, and how they are built to not last to generate a steady revenue for manufacturers. It's quite interesting in this day and age, with resources being more scarce and pollution more of a factor, and yet we produce to throw away when we could just choose differently.

So yeah, good choice Smile

Brightness is indeed the wrong word to describe its light...

I ordered them as such.

Exactly that.

When all went well, on Saturday evening all is ready, and I can stuff the lamp with the bulbes. Yay!

About the relation of lifetime, brightness and voltage (from the german wiki page "Glühlampe"):

Translation:

Title: Lifetime and brightness in dependence on the voltage

X = Voltage in %
Y = Changes in %

Currently the voltage here is 230 V, but there are tolerances ~ 15%. This +15% peaks sucks a lot of lifetime out of light bulbs, as you can easylie see in this graphic.

After installing the dimmer today, the lamp is in use now. as promised, here some photos.

First light:

The complete living room:

It is a wonder light with style. The light looks a bit sepia like on old photos, but sepia is more yellow-brown, but my light is orange-yellow. Hard to describe, I miss the orange color on the photo.

All in all, I love it's design and light.
