Explosive Growth for LED Lights in Next Decade, Report Says

Next-generation bulbs to capture nearly 50% of lighting market by 2020

By Amy Westervelt

May 13, 2010

At the LumiSmart product launch earlier this month, Cavet executives showed on stage how their product had delivered a 40 percent energy savings at the manufacturing facility.

Later this year, the firm plans to release a related demand-and-response product, which will allow property managers and utilities to set building lighting systems to automatically power on and off, and dim, according to the availability and price of electricity.

Others Hedging Their Bets Elsewhere

While Cavet is focused for the time being on making fluorescents more efficient, another smart lighting company, Siemens spin-off , is hedging its bets by focusing on controlling and automating lighting—no matter the light source.

EnOcean's sensors, transmitters and controllers have ultra-low energy requirements, allowing them to run off of so-called "harvested energy" from ambient light, sunlight and electrical cables.

For its part, U.S. industrial giant General Electric has decided that it's going to be ready and waiting when the residential LED market blows up. The company recently the late 2010 or early 2011 release of its LED bulb shaped like an old-fashioned incandescent bulb. Although GE is not the first company to figure out how to make LEDs more "bulb-like." the fact that the inventor of the bulb is making an LED version is big news.

GE's bulb is guaranteed to last 17 years and consume only nine watts of power, delivering a 77 percent energy savings over incandescent bulbs.

Early adopters will likely rush out to buy the bulb, but with a price tag of $40 to $50 each, the costs could remain a barrier to widespread market penetration.

LED technology is still

LED technology is still costly in comparison to fluorescent bulbs. Fluorescent light bulbs contain small amount of mercury (4 to 20 mg). When fluorescent light bulb shatters, it releases mercury vapor.


Good Post

Nice Post, thanks for sharing.

We are Energy Saving Solutions provider offering various solutions by utilizing the energy of the Sun or providing alternate means to reduce your energy consumption levels and save the environment.

LED Lighting saves up to 70% of your Lighting bills.



I thought your post on LED lighting was very interesting.  LEDs are far superior than its predecessors in that they use less energy, they have a longer life and they are better for the environment.   While the initial cost of LEDs is higher than incandescents and CFLs, it will be offset by the energy savings and the long life of the bulb.  It would be beneficial for any household to make the switch over to LED lighting.  I currently work with Sharp, but I have always been a fan of their products they have to offer.  If you are in the market for lighting, I recommend you check out their <a href="">LEDs</a>

Cost is coming down

The cost of the led lights are coming down. In few years time it will replace CFL and other outdoor lights

LED Lights

After observing the massive growth of , it can be said that in the upcoming future, advertising and marketing of any business will be done completely from them. With the spend of time, their quality is also improving. Their softwares are also introduced in the market due to which a big LED lighting system can be controlled and operate from a software.

Lighting Design

We are a Design, Manufacture and Installation company who has helped many companies add impact to their signage by changing there lighting system to LED. We have also designed, manufactured and installed for casino across the country using the LED lighting system and have been able to really give our customers a good deal with a lighting system that is energy efficient, last longer, can be programmable to change colors etc... and is safer for the environment.

While I don't feel the

While I don't feel the technology has fully matured, it's definitely reached a point where it's at least good enough to use for many applications. There are some applications where I don't think we'll see LED lighting in large scale but for every day use, I believe the writing is on the wall.

LED lights will save our planet...

LED light bulbs are non-toxic and not made from hazardous materials.

Fluorescent light bulbs contain small amount of mercury (4 to 20 mg). When fluorescent light bulb shatters, it releases mercury vapor. Mercury is hazardous and the quickest way for mercury to enter your body and absorbed into your bloodstream is by breathing in mercury vapor.

LED Lights is far from being mass applied

Hi, guys. Although we can list tens or hundreds of benefits of LED lighting, the barrier is the price. As developed countries can afford that price for saving the planet, 4/5 of the human will still not regard this as an alternative to incandescent bulbs.

While LED has come a long

While LED has come a long way, there are still some major disadvantages to using it.
First the light output is considerably lower than that of fluorescent bulbs. Yes it consumes less, but it doesn't light the area as well as a linear bulb. What's more the angle at which the light is emitted is extremely narrow making it difficult to use LED to light up a wide area.
Secondly, as mentioned in the article, LED technology is still costly in comparison to fluorescent bulbs.
Thirdly, there is not product standardization at this point, meaning that when your LEDs start to burn out you may find yourself having to replace the entire system.
This article is great to read to learn more about the difference between LED and fluorescent technology:

White LED is already there and improving so fast

That article os lumiversal is completely uncredible and probably designed to "eat" uninformed minds. Is not scientific at all, they dont show the light sources used, they do not give any reference at all or the way the testing was undertaked. And they have good reasons to put down leds due to theyr main bussines lines.
LED technology has overcome T5 performance more than 2 years ago, you just have to ask CREE or Seoul Semiconductors or OSRAM among others.
