Brian, I have a free flashlight app on my Blackberry which turns the camera flash LED into a torch. It does what you have written, and additionally wants access to my personal information. There is a noticeable burst of 3G data activity each time I switch it on or off.
Paranoid, me?
That would be harry, it takes an infinite amount of energy to store the waste forever according to harry.
I paid about £15 for one CFL, but its a lightwaveRF device with built in dimmer. Works really well.
In your opinion. I don't like halogen much, I want something close to daylight not pale yellow. The way you talk I get the impression you want something like acetylene lamps were when they were the main stage light.
Erm, why?
I suppose when every applience has this, the control of theload is moved to whoever can get in and fiddle with the device. A whole new way to play with the public for the kids who will no doubt delight in turning off Mr annyings fridge while he is away. Brian
Ah, you need a transparent faraday cage round your lamp them. Brian
Tiny - the parts cost very little, and that cost includes all the energy used to make them.
Most of the cost at the moment is profit and recouping R&D. That means there is a lot of scope for the price to drop very significantly, which will happen.
People bullshit about lots of things - it doesn't make them true.
People are adding all sorts of features to light bulbs - value-add is seen as a potentially profitable market, whereas light bulbs themselves will always become commodity items.
Some of these value-add features will probably catch on and be genuinely useful, and others won't.
Ok. So define daylight. But I'd guess you think it is a constant, buy that stupid comment.
I want a reasonably continuous spectrum light source. Which halogen provides.
Does it download new ads when you use it? A lot of the free stuff downloads and displays ads which get renewed ferquently.
Like CFL`s sure embodied energy in manufacture isn`t usually fully accounted for.
Against a glass envelope with metal bits in, an LED lamp has a whole load of different materials in its source and driver, that are all made in different places and moved to be assembled.

You should try one of these babies then:
I can tell you, it's far and away the brightest torch I have ever owned; bizzarely running on a single 1.5V rechargeable AA (which I haven't even recharged since August, when it was fitted. It also has a variable focus beam as well.
Only problem with it really is that sometimes it's just too bright - if you're illuminating something very close, so much light reflects back you can't actually see the object you're looking at!
Woss that got to do with anything. The supplier isn't going to sell you them at a loss, is he? He has to pay all the costs involved in "a whole load of different materials that are all made in different places and moved to be assembled".
Isn't the cost of doing anything "forever" infinite?
"Compnaies ... must in the long run find a new way to make money, which could include selling lighting services as well as connectivity hardware and software that ties digital lamps (LEDs are semiconductors) into information networks"
Am I alone in finding the idea that "normal" consumers will pay for their lighting to be connected into some sort of network (for whatever benefit), laughable
tim
Its the lighting industry, home of cartels since the beginning, selling at a loss is simply one tool in the box.
Far Eastern economics appear to have little to do with material costs,price of CFL`s dropped below manufacture cost at some point.
No. I'm more worried about what it's uploading.
Crazy that the light can't be used independently of the video camera out of the box.
I've got similar ones from China, and nowadays use them in preference to my Maglites.

Well, they're prepared to send money to Nigeria, will click on any link and believe in global warming, so it seems very likely to me! The wording possibly should have been "whatever improbable benefit"?
and will pay extra for bundled TV to "lock" themselves into the same Telco for all of their telecoms needs, just because it comes through a box that's supplied for "free" without first discovering that they can buy a box that does exactly the same thing for 50 quid if they install it themselves.
I really though that the Telcos would never manage to con Joe Public into falling for this scam. It seems I was wrong!
