So much for discouraging incandescent light bulbs

[CHJ]

Just received a marketing mail promoting these.

Funnily enough I was in a restaurant mid week and spotted this type of bulb in the over table lighting fittings and wondered why no low energy use.

Guess mood ambiance scores over economy when business model rules.

Don't suppose you've got any more info ? That middle bulb looks just what im after ! I've got a few of those bulbs and only use them occasionally- I like the look of them

low energy bulbs are hideous and don't fit into our old Victorian house at all.

 

[ColeyS1]

Much appreciated guys bit more variation then the ones I've been using.

I think new lighting designs need to be created for low energy bulbs. Cfl and led bulbs look hideous in traditional shades where the light is at all exposed. I have a floor standing lamp which has papershades and 3no 1.5 watt led bulbs give a similar look to dimmed incandescent 25 watt bulbs.

What I really hate is pubs or restaurants that have just replaced bulbs with cfl's and you can the top sticking out. Since they cant be dimmed they ruin any ambience. Hotel rooms are the same.

 

[Myfordman]

TLC are stocking those bulbs.

Afraid I always use the old incandescent bulbs in my home still as I think the low energy ones are rubbish! They just don't give out enough light especially for reading. :evil:

CFL, Halogen and LED bulbs come in a range of sizes and brightnesses and warmths.

You should always be able to find what you need. There are also dimmable LED bulbs.

Here is a hundred watt (equivalent) warm white (2800k) LED. This ought to be the same as 100w incandescent, with about 1/8th the power, and 25,000 hours life.

wow, a whole thread on lights without anyone pointing out they aren't called bulbs.

bulbs are things you plant in the ground when you want daffodils.

the things you are taking about are called lamps.

feel better now. the pedant inside me has left. think I'll go try and grow a light tree in the garden.

note: please read the above with your tongue planted firmly in your cheek.

Since we have turned towards the pedantic. I think these low energy lamps are rubbish too. A study by the US department for energy found that most of the LED lamps overstated their output, sometimes by more than a factor of 2. The equivalent wattages are clearly not equivalent when you try to read by their light, and the failure rates are often optimistic - sometimes giving life expectancies greater than that of the component parts used.

The colour rendering is often awful too. They may be the colour temperature stated, but the light does not have a black body spectrum, so although the light itself may look white, reflected light won't look the same as under daylight - moral of the story - check your paint colour choice at night as well as in daylight before painting a whole room.

These things are just an eco placebo. Make people feel like they are doing their bit without having to make any real compromises. Saving energy on lighting is a drop in the ocean compared with the rest of our wasteful lifestyles. Then there's smart meters. Don't get me started !

I have somewhere an old carbon fliament lamp I found in the shed when I moved in. Still works. Lovely warm light, much like the ones pictured.

Barring two compact fluorescents I've done the whole house in LED's. I can leave every light in the house on inc. two aquaria for less than 200watts. 95% of the population call them "bulbs" - therefore to me they are "bulbs". I've never heard anyone outside the electrical trades call them "lamps".

 

[wcndave]

I believe that any bulbous lamp can be rightly called a light bulb.

Therefore a Halogen lamp that is one of those stick thingies (official naming), is not a light bulb, however the picture from the OP shows only light bulbs.

 

[novocaine]

just because a name is coined and used does not make it correct, a hoover is a vacuum cleaner, a vacuum cleaner is not a hoover.
the OP's image even gives you a clue, "decorative lamp", they could also be called globes, but that just sounds odd.

as said, I was being a pedant and it should be read with tongue firmly in cheek, I call it a bulb same as every other bugger does.

Do not feed me, I am acting like a troll.

 

[wcndave]

As for tony, not sure why you think a few billion people saving 90w per lamp is going to have no effect... the fact is you CAN get LED lights that have almost the same effect as incandescent. However you definitely get what you pay for, cheap LEDs can be awful.

If LED had been invented first no one would be complaining about this loss of "warm light", however you can certainly bathe in the warn light of a 90deg sun when our planet has all melted up....

I too have replaced almost all my lights with LED, and where I really really need a special type of light, I have a Halogen bulb (upstand dimmer in living room for example).

With 3kw total power in my house, reducing my power from 2kw to 200w has a massive impact.

I do think that early CFLs were really horrible light, and this plus the early cheap LEDs has put people off - but 95% of energy going to heat cannot be the right way to light our lives.

I like feeding time :twisted:

If you want to actually buy a hoover, or sellotape, or pritt-stick, or a jacuzzi, cellophane or velcro, bikini or asparin, then that's fine. So a light bulk is correct, until it's not. However unlike the other examples above, it's not a brand, it's a form.

please feed me

I didn't say no effect, I said it was a drop in the ocean, a placebo, in the scale of wastage in modern life.

The "warm light" is deeply rooted in our psyche. Sunlight is quite close to a black body spectrum. Firelight is. Candle light is. All the types of light we associate with a pleasant ambience. CFLs ar a long way from it, LEDs may be better but are still no way like daylight.

I have some CFL's in non-critical places and halogens where I need nice light. Some old style lamps in little used locations like the bathroom, where instant nice light is desireable but they are not on enough to matter. But energy saving bulbs don't really reduce consumption from 2kW to 200W do they, because I for one turn out lights I'm not using, so my lighting takes maybe 100-200W when in use even using halogen lamps. And, half of the year, the heat is not waste. And a bit of glass and metal must take less to make, and recycle.

As with everything, from tools to vehicles (lights being somewhere in the middle) there will always be the people who do not want to change when new tech comes along, the train would strip people of there flesh, the car was so scary it would never replace the horse, the internet was dangerous and full of perverts (oh wait, nearly right).

We are still in the infancy of LED lights, the method by which they are produced has changed beyond anything recognisable to the people who worked in the industry 10 years ago, the same has to be said for CFL although this technology has been around a lot longer and has it's feet well under the table so to speak now, they are now inside the size of an incandescent, in an enclosed fitting they are all but impossible to tell the difference, only when you see the magic orb of wonder (new name for lamp/bulb) does it make a difference.

as someone who has moved in to a new house and is ripping out all the nasty stuff the previous owner left behind I am replacing it all with CFL and LED where possible, the rest are halogen, nothing to do with saving the planet, it is saving my wallet (all for saving the planet though), even have a few 5w LED lights in the workshop, over the lathe and workbench, they are great and back up the full fluorescents at the ceiling nicely. they are more expensive at the outset, next year they will have paid for themselves in lower energy bill.

yey feeding time.
only one of the shapes above would fit the definition of bulbous "fat, round, or bulging".

 

[wcndave]

I think the ocean is made up of drops.

A few billion of them is not to be sniffed at. It of course does not mean we can ignore everything else that we do that wastes energy. Having put in a 7,000 Litre rain water tank, and enough insulation to keep a pooh bear factory stuffed for a decade, I am all for doing what we can. With a family of 4 we can easily be in four rooms at once, and I had 2x300w halogens in my workshop. there are 6 60w halogens in the kitchen, and a spotlight bar of 5 lights in the living room, that would be > 1kw already, so it can happen.

What I meant about being used to it, is that if Edison had stolen the idea from someone who did an LED light first, we'd never complain. You could always use candles if you like them so much ;-)

the heat is wasted half the year? and lets say in the hall / outside / bathroom you don't need it, then we can say 70% instead of 50%. 95x70 = 66% wasted energy, still pretty bad.

I'm off to the sharpening debate now, might pop back later!
