Home Lighting : LED Grow Lamps & Plant Grow Lighting

June 26th, 2009

Lower Costs - Led grow lights can save you money!
LED Plant Lighting : Product life is 100,000 hours of 24/7 operation with no light degradation
creating additional savings over the bulb/ballast replacement costs of other indoor growing lights.

Targeted Light Output- Unlike “broad spectrum” lighting, which produce a lot of light plants can’t use efficiently,
our led grow light delivers the colors of light used by plants for efficient and healthy growth. By leaving out light
plants don’t need, we provide still more energy savings over the traditional indoor garden light.

Longer Bulb Life- The expected life of our LED grow light is 12-18 years of operation. This is ten to twenty times
longer than a typical grow light and twice as long as high wattage LEDs.

Less Waste Heat- Our led grow lights are merely warm to the touch, even after operating for hours, greatly
reducing your cooling costs.

Greater Safety - LED Grow Lights are safer to use in your home, office, or school. No glass parts, mercury, or
lead are present. The low heat and low voltage of LED Grow Master LEDs greatly reduce the risk of fire and
shock, especially in wet environments that are present when growing plants indoors.

Light Weight - Each LED Grow Master indoor garden light weighs less than a pound.

Less Fragile - The glass bulbs of other plant lighting are very fragile. Our LED plant lighting has no glass parts,
and are much harder to break.

Less Environmental Hazard- Metallic vapor and fluorescent lamps all contain mercury, a heavy metal identified by
the U.S. Government as hazardous to the environment and our landfills. Our LED grow light contains no mercury
and represents an environmentally friendly lighting choice.

No “White Light” Glare- Other indoor growing lights use technology designed to light rooms and buildings,
which makes them very bright to the human eye. The LED plant lighting delivers light that is very bright to plants,
but relatively dim to people. Your plants get what they need without the “white light” glare you don’t want, making
our led grow light welcome in your kitchen and living room, instead of your basement.

Less Watering- When growing plants indoors, your plants will transpire less under LED grow lamps, letting you extend the
time between watering cycles. If you need to leave your plants unattended for a few days they’ll have a better
chance of surviving if their grow lights aren’t drying them out.

Enjoy Delicate Blooms Longer- Flowers are very delicate, as can be seen from the spotting and edge burning
they get outdoors. Richly colored rose petals fade quickly under the summer sun. This is not true when flowering
plants bloom indoors under the LGM led plant light. Miniature roses have been grown using led light with blooms
that were picture perfect and unblemished, with some varieties having flowers that lasted for months without
change.

Greater Versatility Lets You Be Creative…

Completely Directional- Most plant lighting can only be mounted one way - suspended from the ceiling and
pointing toward the floor. And even if they can be hung different ways, their bulky reflectors make this a lot more
difficult than you might like. Small and light weight, the led plant light can be positioned any way you like, ensuring
all parts of your plants get the maximum light they need.

Use Only As Many Lights As You Need- With more cumbersome LED plant lighting, you often have to bring your plant
to wherever you are able to mount the light. Wouldn’t it be better to put your plant where you want it…on a table, on
a shelf, on a windowsill…and bring the light to the plant? The small size and light weight of our led light let’s you
bring the light to your plants. If your plant has a cascading form, arrange lights to shine on the plant the way it
naturally grows. There’s no need to light up half of your living room just to try to grow a few prized plants indoors.

Home LED Lighting : Using LEDs in your House and Home

December 28th, 2008

Whether you are just intrigued by the new LED home lighting products appearing in many stores, or are keen to contribute in the fight against climate change (global warming) or simply want to save money on your fuel bills, the fact is that LED home lighting is the future.

So sooner rather than later, you’re going to have to learn what this future means to you personally and how you can in fact benefit considerably from new low power consumption domestic LED lighting.

This article aims to dispel some of the confusion that surrounds the many lighting solutions currently available to consumers and provide a useful guide to evaluating and buying Home LEDs.

Where should you use LED lighting in your home? The nature of LED lamps is that they emit is directional light - focused on a single area. So they are a superb choice for lighting applications that have similar characteristics, such as:

  • spot lights
  • accent lighting
  • tracks and clusters
  • recessed down lights
  • security lighting
  • courtesy lights
  • desk lamps
  • decorative & feature lighting

Many homes have this kind of lighting in kitchens, bathrooms, hallways and basements - anywhere that needs to be brightly lit. They also have a great usage for plants & growing herbs with: LED Grow Lighting. Plants LOVE the cool, low powered, high energy output of LEDs, and can be placed extremely close to the plant or herb for BEST flowering results. Save hundreds on your lighting costs using LED Grow Lamps. Try one out today and see the amazing cast, and output and yield of your lusciously green crop!

LED units also function well in strips, so under kitchen units and inside cupboards are ideal - also they give off almost no heat, plus the extremely bright light is needed in a fairly confined area rather than spread widely.

What LED lights are presently less adept at is all round illumination - from say a table lamp with a lamp shade.

Key point one: keep to what LED home lighting currently does best - bright directional lighting.

Something that confuses many people about LED lights is “color”. This is not color as in green and orange - it is “white color”. LED lamps come in a variety of “white colors” - from soft, warm illumination to a sharper, colder effect.

As a rough guide, “warm white” LED lights work best indoors while “cool white” is a good choice for outdoor LED lighting where you typically want sharper definition and illumination that approximates daylight.

Key point two: understand the LED light “color” scale.

Next, we get to input power ratings or wattage. We are used to knowing that 100w is bright while 40w is suitable a lounge maybe and 10w is essentially a courtesy light. But home LED lighting doesn’t conform to this scale for the simple reason that LED light bulbs require very low power consumption since nearly all their input power is converted to light and almost no energy is wasted as heat.

To replace a 50w halogen lamp (both MR16 and GU10 fittings are widely available for LED equivalent replacements) you would be looking at an LED spot light rated at 7w. Step up to a 12w LED and you’re taking on a regular floodlight.

There is a further complication to consider. The LED “color” affects how bright it actually appears to human eyes - cool colors seem sharper and apparently brighter than warm colors. Mentally adjust the wattage equivalent up or down a fraction according to the LED color.

Key point three: LED lights are very low energy units, so get used to a much lower wattage scale.

In addition to color and wattage, the angle of the light beam from an LED lamp has a major effect on how it looks and how bright it appears.

A narrow angle of less than 40 degrees will focus all of its light onto a small area which will therefore appear very bright. A wider angle of 70 to 120 degrees will cast light over a wider area and thus more will be illuminated but less brightly.

Key point four: take into account the beam angle of any LED lamp.

Finally, where to buy LED home lighting? If you are new to domestic LED lighting then the answer is: wherever you can actually see the LED light unit or at least a good photograph so you can assess how a particular LED application will appear in your own home before you buy it.

Specialist lighting shops often have displays you can look at (and also catalogues with photographs), and many big DIY and general stores now include LED units in their display lighting.

Unlike conventional light bulbs, LED home lights are a long term investment which will save you a lot of money in the decades to come but the costs are all upfront, since most LED lights actually cost less to run than to purchase. They last for a very, very long time so you do not want to make a hasty purchase you could be stuck with for many years.

As ever, quality and reputation are factors to consider closely. An LED product from a recognised manufacturer that has a reasonable amount of information on the packaging is likely to prove a reliable product that performs as you would expect - whereas a cheap no-name LED unit on eBay is probably not.

That said, buying LED home lighting online is cost effective and perfectly safe once you have decided which particular types of LED lamps suit you and you are careful to buy from reputable web sites that offer warranties.

Key point five: quality and reputation count most; buy from established, reputable suppliers.

LEDs And Smart Lighting Could Save Trillions Of Dollars, Spark Global Innovation

December 26th, 2008

ScienceDaily (Dec. 20, 2008) — A “revolution” in the way we illuminate our world is imminent, according to a paper published this week by two professors at Rensselaer Polytechnic Institute.

Innovations in photonics and interior LED lighting will lead to trillions of dollars in cost savings, along with a massive reduction in the amount of energy required to light homes and businesses around the globe, the researchers forecast.

A new generation of lighting devices based on light-emitting diodes (LEDs) will supplant the common light bulb in coming years, the paper suggests. In addition to the environmental and cost benefits of LEDs, the technology is expected to enable a wide range of advances in areas as diverse as healthcare, transportation systems, digital displays, and computer networking.

“What the transistor meant to the development of electronics, the LED means to the field of photonics. This core device has the potential to revolutionize how we use light,” wrote co-authors E. Fred Schubert and Jong Kyu Kim.

Schubert is the Wellfleet Senior Constellation Professor of Future Chips at Rensselaer, and heads the university’s National Science Foundation-funded Smart Lighting Center. Kim is a research assistant professor of electrical, computer, and systems engineering. The paper, titled “Transcending the replacement paradigm of solid-state lighting,” will be published in the Dec. 22, 2008 issue of Optics Express.

Researchers are able to control every aspect of light generated by LED lights, allowing the light sources to be tweaked and optimized for nearly any situation, Schubert and Kim said. In general LEDs will require 20 times less power than today’s conventional light bulbs, and five times less power than “green” compact fluorescent bulbs.

If all of the world’s light bulbs were replaced with LEDs for a period of 10 years, Schubert and Kim estimate the following benefits would be realized:

  • Energy saving LEDs : Total of 1.9 × 1020 joules
  • Electrical energy consumption would be reduced by terawatt hours
  • Financial savings of $1.83 trillion
  • Carbon dioxide emissions would be reduced by 10.68 gigatons
  • Crude oil consumption would be reduced by 962 million barrels
  • The number of required global power plants would be reduced by 280

With all of the promise and potential of home LED lighting, Schubert and Kim said it is important not to pigeonhole or dismiss smart lighting technology as a mere replacement for conventional light bulbs. The paper is a call to arms for scientists and engineers, and stresses that advances in photonics will position solid state lighting as a catalyst for unexpected, currently unimaginable technological advances.

“Deployed on a large scale, home LEDs have the potential to tremendously reduce pollution, save energy, save financial resources, and add new and unprecedented functionalities to photonic devices. These factors make photonics what could be termed a benevolent tsunami, an irresistible wave, a solution to many global challenges currently faced by humanity and will be facing even more in the years to come,” the researchers wrote. “Transcending the replacement paradigm will open up a new chapter in photonics: Smart lighting sources that are controllable, tunable, intelligent, and communicative.”

Possible smart lighting applications include rapid biological cell identification, interactive roadways, boosting plant growth, and better supporting human circadian rhythms to reduce an individual’s dependency on sleep-inducing drugs or reduce the risk of certain types of cancer.

NYC to Start using Retail LED Lighting

LED Home Lighting used in NYC

 

 

NYC’s Department of Transportation has started testing LED street lighting around the Big Apple. If successful, all of the city’s 300,000 street lamps could one day be made up of LEDs and interior LED lighting.

Of course the power consumption of home LEDs is much lower than that of standard bulbs. Heck, even lower than that of CFLs.

But the OVI contract doesn’t only replace the current high-pressure sodium lighting, but also introduces a whole new lamp pole as well. While I am a fan of retail LED lighting, I am quite fond of the Gotham-styled lamp poles. Keep your paws off, OVI!

Okay, maybe the new poles aren’t so bad. The poles will be between four to six feet, and have up to 100 LEDs each. They will have four light sources per pole, and can create different light patterns.The light footprints can be tailored for parks, street corners or mid-block.

The city will begin testing with a mere six poles, and the testing period will end by fall of 2009. But even if the city approves the highly-efficient LED lighting, it’s likely they won’t roll out 300-thousand new lamp poles all at once.
