LED light bulbs to cut energy bills by 75%

LED light bulbs are not a new invention but currently they are a costly alternative to the more traditional incandescent light bulbs.

A report from London based Metro newspaper indicates that scientists have discovered a new method for producing the man-made material on silicon, instead of costly sapphire. In turn the cost of the light bulbs will be cut from £20 ($28) per bulb to just £2 ($2.80).

The bulbs can last up to 60 years, burn for 100,000 hours and are 12 times more efficient than conventional bulbs and could be on the shelves in two years. The impact to the environment and the economy is that offices and homes won't need to replace them for years and that could potentially cut energy bills by 75% within 5 years the inventors claim.

"This could well be the holy grail in terms of providing our lighting needs for the future," said Prof Colin Humphreys, who helped develop the bulbs. "The five-year timescale is a conservative estimate," he said. "I'm hoping the bulbs will be on the shelves much sooner."

I think led lamps must be used to light highways first... Because most highway lightning lamps (mercury) are 400W! Try to imagine how many we have...

The issue is that you cannot use pure white LEDs on highways as it would not be able to cut through fog and if you live in an area with snow, you would not be able to clearly tell where the road is in whiteout conditions. The white light would reflect off the snow.

Its kinda like those bright Xenon headlights that are so white that if you're in a snowstorm you're screwed.

That's an easy one. Just use a yellow-tinted screen over the bulb. A lot of street lights use that around where I live, because of the fog and the snow.

If you think that these LED's will last like 20+ years then you are wrong becouse manufactures won't have enough of profit.

People don't think about that, and it's more than true. It's like the drug companies, there is no money after you cure Aids, Cancer or whatever.

This sounds great to me. I was wondering if anyone knows what kind of bulbs are used on some of the cars I see at night. They have a really bright whiteness to them. Are these LEDs being used for cars? I don't see many but when I do see one it stands out. Last night as one passed by me and I looked at the pavement in front of his car and the road was really white.

I'm thinking of changing mine as well. White is much better than the usual yellowish bulbs and you can spot potholes better haha

I'll be glad when I can pick up a set of these, better than either type of bulb that is on the market at this point (although I don't mind the compact fluorescent bulbs, having mercury in them isn't exactly environmentally friendly).

So like... will this ever be allowed to happen? I thought they had come up with ways to prolong the life of Light Bulbs years ago but it all gets burried. I mean, this would be the end of Light Bulb companies a cheap bulb that lasts so long. The less often you need to buy bulbs the harder it is for them to stay in business.

At a time when there is such a huge 'credit crunch' and business are struggling to keep going, this is going to be good for energy saving, but bad for the people selling them. The impact would also be to everyone in the chain that supplies them.

Just a thought.

I don't believe 75% can be saved with LED lights..... I'd expect water heaters, ovens, freezers and fridges to consume the majority of the energy bill.

They aren't talking about 75% of the total energy bill. They mean that the LED bulbs only use 25% of the energy of incandescent bulbs. The article and title is very poorly worded.

True, according to an electrician I've heard talking on TV, bulbs total to 20% of the energy bill. You need to focus more on water heaters, electric kettles, electric heaters etc... Get a solar panel for water heaters, use normal kettles on gas instead of electric kettles, and use gas heaters instead of electric heaters. In the garden or outside, use solar lighting. Do not leave appliances on standby, switch them off completely. Avoid spotlights, and get Energy Saving bulbs or LEDs if possible.

I think the article title is worded fairly, I understood what it meant...if you believed a light bulb would drop your energy bill (ENTIRE ENERGY BILL) down to 25% of what it is now, you're a moron. Use common sense next time.

Actually, no, it is not worded correctly. The title and the article clearly state that the LED bulbs would cut energy bills by 75%, which is not the case. They will cut energy consumed by light bulbs by 75% compared to incandescent bulbs. Just another case of lazy writers not checking facts.

There is some money to be saved, but not much when it's cold outside. It's dishonest to make it sound like the extra energy needed for incandescent bulbs is just wasted.

If you are talking about using the heat generated from incandescent bulbs to heat your house, you should know that they are a very ineffecient method of doing so. Similar to leaving your refridgerator door open to cool your house during the summer.

Really? You mean incandescent bulbs create cold?

Stop talking nonsense. The two are nothing alike.

I am looking forward to these, but not looking forward to the result of people replacing their mercury CFLs. I am not hopeful that most know how to properly dispose of them

I hate the blueish light LED bulbs make... everyoen says they are "pure white" I think it looks nothing like sunlight... sunlight always has a warm feel to it, the LED lights have a cold feel to them... the current warm color CF bulbs out there feel more like sun light to me... and seem also more ike incandescent lights also

xorangekiller, CF are compact flourescent. I replaced every bulb in my house with them early last year, They have more than paid for themselves in energy savings (probably paid for themselves after 2 to 3 months). I had to replace 3 that went out, but they were being used in a bathroom where the lights are usually only on for a few minutes at a time, which does tend to shorten their lifespan.

Anything has to be better than the existing energy-saving bulbs. They are just awful. It's like looking into an old Victorian house when I see homes that use them. Everything is so dim and with a dirty orange tint, like it's being lit by candles.

sounds like all you have saw are warm white cfl's....you need to look at the cw cfl's to notice a difference...that or check out the daylight lamps

Thanks. I have two in my living room and I've no idea what they are to be honest. They were sent by our energy company. But like many others I see, they produce a dirty colour that is really uninviting. I presume the cw is cool white? I'll look into it, thanks!

The cool white produces a blue tint and cool feeling... personally I hate them, they make the rooms feel like you are in antartica or something with the blueish glow... the CF bulbs I have feel more like sun light and they are not cool white or "natural white" bulbs... made by GE

i thought LED's where already available?

or do they mean for home use like indoor lights like how we have standard light bulbs? ... cause if that's the case they would be worth every cent not only cause it costs you less on electric bills but cause it's one of those things you can buy and forget about they last that long ;)

the thing is though even with LED's being alot more efficient in general... will it make a 'noticeable' difference on monthly electric bills? , that's the question ;)

sad thing though is even if they save u money... once every one has them all the electric company's will do to get more money is to raise prices of electricity again .... someone needs to put a limit on how much they can charge cause right now they basically have a monopoly on the electric stuff and can pretty much charge whatever they want and prices keep going up and up in the last 5 or so years ... there just greedy cause it aint like the power company's will go out of business anytime soon with the prices they had even a few years ago.

but i guess even if we keep getting screwed... at least there will be less electricity used and the planet and our natural resources will last longer worst case from it , which cant be to bad of a thing.

The spotlights in my computer room have LED bulbs in them. They cost me £1 + shipping (£5.69 per pulb) from Hong Kong. They replace my 50 watt GU10 Halogen spotlight bulbs. They each have 60 ultra-bright white LEDs in them and are comparable in brightness to the 50 watt halogens they replaced. They are a little wider at the light end though. If I remember correctly, they use 3.5 watts of power.

200 watts (50x4) vs 14 watts (3.5x4) is quite a power saving and I'd recommend them to anyone. Don't go for the cheaper 24,32 LED versions though, nowhere near as bright and not really suitable as main room lighting.

I saw these on televison last night and wondered about them. Thanks for the information. How long did they take to be delivered from HK?

Took less than a week to arrive, due to the low cost there were no import charges either.

Normal bulbs I dunno. They suit spotlights well as LED light is unidirectional. I suppose in theory they could arrange them in a ball, but I've never seen any like that (I've not really looked).
