Modern bulbs are rubbish

light-bulb

You might be saving the penguins whenever you turn on an energy-saving light bulb, but some new research has shown that you’re increasing the chance of barking your shin on an unidentified object that lurks ahead of you in the gloom.

That’s because the starch-coated boffins at Engineering and Technology magazine (no, us neither) have decreed that energy-efficient light bulbs lose on average 22% of their brightness over their lifetime, making them as useful as a plastic sneeze or a runaway dog.

The boffins tested 18 of the miracle bulbs over a 10,000 hour period to come up with the results, during which time three of the bulbs stopped working altogether! Traditional bulbs lose no more than seven per cent of their brightness but usually only last for 2,000 hours.

So, are we prepared to put up with this light-loss tomfoolery or should we go back to ye olde bulbes, killing countless penguins as we screw Mother Earth like she’s some kind of giant second-hand sex doll? Well? Eh??

    Simply replace the bulb when it becomes too dim. It'll still have lasted far longer and used far less energy than a traditional bulb.

    @Mark I didn't expect to see anything sensible on this page, after that attrocious "news" item. Thank you.

    Honestly, what type of bollocksy research is that? It doesnt take a genius to figure out, traditional lightbulbs, 2000 hours, 7% loss. new lightbulbs, last five times longer, but only lose three times as much brightness. Which makes them 60% better than the old bulbs. And theres an even easier option. If they lose too much brightness, just replace them? They're only like 20p for 5 anyway.

    We'll be getting LED light bulbs in a couple of years anyway, why worry.

    Yeah, i say fuck her

    It hurts but Archer is spot on with this one.

    Bigger problem is they take 4 hours to warm up so you've fallen down the stairs in the gloom and been carted off to casualty thus nullifying any "carbon footprint" saving. Thank god for my stash of proper 100w bulbs that should last until somebody comes up with something that works (maybe piggy's LEDs whatever they are)

    I doubt the very first lightbulbs were that good at the start, its unfair to compare the two. I'm sure in a few decades energy saving lightbulbs will be even brighter, last longer, cheaper etc etc

    They may actually work with a traditional dimmer switch eventually.

    The new lightbulbs are GRIM. Horrible, depressing greenish light instead of lovely warm tungsten. Does anybody know if there are any expensive ones with the same colour temperature as tungsten bulbs?

    As above: Energy Saving lifetime: 10,000 hours Regular lifetime: 2,000 hours. Regular loss during first 2,000 hours: 7% ESL ": (presumably) 0% Regular loss after first 2,000 hours: 100% ESL: 22% Regular cost per year: 100% ESL: 20% I don't know about you, but looks to me that the ESL bulbs are, somewhat, better, all round. Except: Regular perceived light emital: 100% ESL: 60% So, erm... just install 2? Given they last 80% longer and cost 80% less... It's win win, people.

    stop whining, do the math re cfl's going into decline... (real daily meail reportage (spits) & there are low energy Halogens from philips that use 20 watts & put out 60 watts, been using em succesfully in my kitchen & conservatory for around 4+ years now, so if you cannot see anything other than cfl's open your eyes! stop bleating & start finding viable alternatives, they're out there! (we use CFL's, Low enetrgy Halogens, LED floodlighting ...does well if you apply the right product to the right application, beyond that you can only blame yourself for your own ineptitude!

Their only agenda is to teach us that global warming is real. Sorry, call it 'climate change' now to avoid explaining why over the last 5 years it's been getting cooler. In the 70's they were telling everyone we were heading into a new ice age. Wuck Fits.

    Correction, @some@ Megaman bulbs apparently do. They call them the rather clumsy "dimmerable" series.

    >> You dipstick – believe what the BBC funts tell you? Thanks but, no, I believe what the Institution of Engineering and Technology tell me (as reported in said BBC article). I tust their experience in engineering and technelogical subjects may be slightly more rounded than "Jack of no Trades".

    Seriously though, I do believe that we are teetering at the point of no return. Even USA & China are waking up to the evidence (as is anyone with a brain that's not located in a dark, smelly place!) So every little helps!

    Oh so tired of living in the dark.It is like having cataracts.No wonder we are fed up.Am going to put the heating on full to warm the cockles of our hearts.Make the radiators glow!

    Mayor John Tonello said the LED lights will save the city 60 to 80 percent in electric bills. The city has been experimenting with different LED lights for municipal use and street lights. They will also emit a more natural illumination Color: LEDs can emit light of an intended color without the use of the color filters that traditional lighting methods require. This is more efficient and can lower initial costs. Ask your city official to do the same.
