This is why LED’s are the light bulbs of the future

earthled.jpgIn researching this blog post I’ve learned much about LED light bulbs that is worth shouting from the rooftops, and have certainly changed my views on lighting options for my home. Did you know that LED light bulbs now perform on a par with incandescent light bulbs as far as quality and consistency of light goes? Fantastic. That would mean nothing if they didn’t also use around 10x less energy to produce the same amount of light, which they do.

But we have already switched from incandescent to compact fluorescent light bulbs in our homes. They’re also energy saving bulbs aren’t they? Why bother to switch again? On this count, firstly LEDs last 5x longer than compact fluorescents, that’s 50x longer than old-fashioned incandescents. And secondly, toxic mercury is used to produce compact fluorescents. This is not a problem when the bulbs are recycled correctly, but with limited facilities and in many cases the inadequate advice provided about disposal of the light bulbs, there is a potential for the dangerous leakage of mercury vapour in our homes and in the transport of the bulbs to landfill. LED light bulbs don’t contain any hazardous substances, and are very durable, so are unlikely to become damaged if dropped.

EarthLED provide direct replacement bulbs for your existing light fittings and lamps in a number of different formats, the most powerful and stylish of which is the XR series. The XR-10 uses only 10 Watts but pumps out the equivalent amount of light as a 100W incandescent whilst being an objet d’art in it’s own right, or it’s little brother the XR-5 that comes at a lower cost and with a lower output, but is still a very stylish light bulb.

And while the XR series perform best while in a downward facing position or directed at an object, EarthLED also have a solution for table lamps and light fittings with lamp shades with the CL series. These are dispersion LED bulbs that cast a natural light pattern like traditional incandescents. They are available in a 3W and a 5W version (3W is comparable to a 45W incandescent, and the 5W is comparable to a traditional 75W).

Finally, the GL series of LED light bulbs from EarthLED provides the equivalent of a 50W light bulb at an affordable price.

While LED light bulbs may seem expensive at first glance, EarthLED provide some figures on their website to put this into perspective:

One 5 Watt EarthLED GL costs approximately $2.00 to run per year at 12 hours per day. Since it was on for approximately 4000 hours it still has nearly 10 years of life! Throughout its entire 11 year life a GL will cost approximately $50, including the cost of the GL, while a traditional fixture using an incandescent bulb will cost nearly $250!

EarthLED light bulbs are priced from $29.99.

LEDs are a great step forward. My condo is all LED, and I love them.

The EarthLED bulb pictured has OK light, but creates a giant halo effect. This halo is very annoying. Look for bulbs with 3 or more LEDs to avoid halos on your wall and ceiling.

It isn’t correct to state that LED’s contain no hazardous substances. The semiconductor is doped with various impurities to produce the light. This would not pose any issue for disposal though but is worth bearing in mind if you are handling damaged LED’s.

Sponsored Post? Does that mean it was advertising for the LED bulb seller? At over $50 for their cheapest bulb you would have to save a whole lot of electricity to pay for them. If you want to try some LED light bulbs on the cheap http://www.shop.donsgreenstore.com has a sample pack of 5 different bulbs for $57 with free s/h. About the best price I have seen if you want to give LED’s a try. Warning: these are not nearly as bright as regular bulbs.

This is false advertising. The Xr-10 is claimed to put out 400 lumens which would be comparable to a 35-40W incandescent, not 100W as stated.

One other addition… I am a big fan of LEDs and plan to buy many in the future but at this early stage in the game you really do your research before buying and definitely get opinions from those with experience. I purchased several CL series 5W bulb (warm light version) which claims 75 watt equivalent incandescent. The light quality is great and gives off a nice white, however, I must take exception with the marketing claim that it is 75 Watt light equivalent. I bought these bulbs to replace 60W incandescents with something that I hoped was a bit brighter. These bulbs were in fact considerably dimmer than even the 60Watt bulbs they were replacing. They are more like a 50W equivalent if you ask me. In other words, take these over embellished marketing claims with a grain of salt. In some ways these types of claims do the industry a great injustice because the claims never meet expectations. Most people that purchase an item expecting one thing and getting something inferior tend to get a little ticked off. I have many family members that bought CFLs early in the game and were very disappointed with the longevity and brightness of the bulbs and to this day bad mouth these products despite the fact that these products have gotten much better. My point is that LEDs have enough merit on their own and if they simply were to market this as 50W equivalent instead of the 75W equivalent (which is clearly is not) most people (myself included) would have a much more favorable view of these products.

I’ve actually purchased several of these bulbs and have been quite happy with them. While I do not have equipment to verify light output, I think the key here is strategic placement of the bulbs for most effective utilization of their output.

I happen to love the clarity and color tones these provide and they are a welcome departure for frequent headache sufferers like me who cannot stand CFL bulbs.

Are LEDs Lights of the future? Most Definitely.

I have tested numerous LED light bulbs.
The prices were high.
Some had pook quality control and failed after a few weeks.
I hope the industry will grow with lower pricing, better quality control and more variety with higher lumens.
I promoting the LED product it should be stated the amout of watts it is equivelant to.

The Cree LED lights are excellent. I have recently replaced my undercabinet lighting with Cree based LEDS from Insaini LEDs. I used the warm white version (yellowish like incandescent). The quality of the light is excellent.
However, the light output was significantly lower than the halogens that I replaced. I overcame this issue by repositioning the lights and using twice as many lights. The result was a more uniform lighting on the countertops. Of course this added significantly to the cost.
In the end, I replaced 80W of halogens with 14W of LED and I am happy with the result. Note that this is an application where CFL was not an option.
As a result of this experience, I am a firm believer in the quality of Cree LEDs. But we need to be skeptical about the quantity of light output.
Thanks

It’s VERY hard to find any information on LED bulbs on the internet, which shows you how new this application is as home lighting. I think that if GreenLED’s numbers are correct, the 400 lumen bulb that they sell for $50 would be nearly enough to replace a 60 watt bulb. You have to take into account a few other things however, like the fact that the LEDs themselves are VERY directional and so far are only a suitable replacement in a spotlight/can light/reading light situation. They are terrible in a shaded lamp or an old fashioned lamp style porch light (pointed up, the bulb is going to shoot light right through the top of the shade and almost no light to the sides).

Yes, great, but at $100 for a single fitting XR-10 I think somebody is missing the point. At prices like that I think the planet is doomed.

Get a grip.

I have just ordered several LEDs from Giftsmax.com and I’ve found that the quality is better than I expected. Although the price is still a bit higher, I believe there will be a price drop this year.

LED bulb reliability – HIGH FAILURE RATES

The life span of LED bulbs is vastly overstated by the manufacturers and vendors. Some of the bulbs I have purchased only lasted two weeks at no more than a couple hours use per day. Very disappointing (maybe 30 hours lifespan).

I am a big fan of LED lighting. Choose a bulb that fits the application (lumens and color) and you will be happy. Unfortunately many manufacturers and vendors overstate (I’m being kind here) their products specifications.
I have purchased 45 LED bulbs and have had mixed reliability.
The good news – some are very reliable. I have five LED bulbs outside that have run dusk to dawn for two years with no problems.
The bad news – some bulbs are VERY unreliable. VERY high failure rates.
I purchased 12 of one type LED bulb and 12 out of 12 have failed (8.5W product 47856 from LEDLight.com). 100% failure rate. To make matters worse they are refusing to replace them now.
Beware of LEDLight.com. This company is selling products that they know are defective. No support for failed LED bulbs. These bulbs are very expensive ($20 – $105) and in some cases last only two or three weeks. They refuse to replace defective bulbs. LEDLight.com is selling known defective products and has bad customer service.

Is LED really as hot as people think ? Not really , the unstable quality , high price are still the Biggest Obstacles . We will watch this war with patience, who will be the king ?
