How Efficient are LEDs?

The main advantage of LED lighting is that it uses less energy than any other lighting options currently available. LEDs, on average, are 80% efficient, meaning that 80% of the electrical energy is converted to light; the remaining 20% is lost to heat energy. Compare that to an incandescent bulb, which only operates at 5-10% efficiency, meaning 90-95% is lost as heat.

Translation, you're protecting the environment, saving energy, and saving money!

How?

Protect the Environment

• You are using less energy, therefore you are producing less green house gas emissions.

• The long life of the bulbs means less trash, which means less landfill.

• LEDs are 100% recyclable, containing no toxic metals, hazardous mercury or halogen gases.

Save Energy

• LED fixtures use 50% less energy than CFL fixtures.

• LED fixtures use 85% less energy than incandescent fixtures.

• LED fixtures don't put off heat like other fixtures, which means less energy used for air conditioning.

Save Money

• LED fixtures generally pay for themselves in less than two years (they have a life span of 20+ years).

• Return on investment can easily be 10 times the initial cost of the product.

• Minimal maintenance and a long life means significant savings over the life time of the product.

Lumens Vs Watts

For years we have bought bulbs based on the wattage, thinking that the higher the wattage the brighter the bulb. But what we need to learn to look at is the lumens, which is the amount of light produced, and not wattage, which is the amount of energy being used to produce that light.

The chart below compares three light sources and the wattage used to achieve the same lumen output. You'll see that LEDs require a lot less wattage (energy) than incandescent or CFL to produce the same amount of light and therefore results in a lower energy bill for the same amount of light.

A good rule of thumb is that 1600 lumens is equivalent to about a 100 watt incandescent bulb.

The Sleeper Sofa Reinvented

Most of us have either a spare bed or a pull out couch for when guest stay the night, and they are only being used a few weeks out of the year.  The rest of the year that space is being wasted or the couch is not very comfortable to even sit on. But why does it have to be this way? Let’s be honest. You have probably thought about changing that room into an office, gym or craft area. You may even have a pinterest page dedicated to it, but you need that sleeping area for when guests are in town too.

But why can’t you have both?

With the Innovation sleeper sofa you can!

Unfurl

What makes these sleeper sofas so comfortable is the fact that you are sitting on the mattress. There are four different types of mattress construction used (see images below):

• Pocket Spring – 7” pocket coil mattress (left)
• Excess Pocket Spring – 10” pocket coil mattress (left)
• Dual Pocket Spring – 7” pocket coil mattress with a 2” pillow top (center)
• No-Sag Spring – No-sag springs with two layers of foam (right)

There are also a few different mattress sizes across the different styles, they are all extra long:

• Twin Wide 45-47”W
• Full 55”W
• Queen 63”W

Splitback sofa and chair

Converting these sofas into sleepers is quick and easy. There is either a ratchet mechanism, like the Splitback sofa and chair shown above. Or it is as simple as lifting the seat up and out and flipping the back down, like the Dual Sofa with arms shown below.

LED FAQ's

What is LED lighting?

LED stands for Light Emitting Diode. In other words, it is a semiconductor that emits light when electricity is applied to it.

Are LED lights brighter?

Not really. For years we determined how bright a bulb was by looking at wattage (energy used) when using an incandescent bulb. But since LEDs use less energy you have to look at the lumens (measurement of lights brightness). In other words, you can get the same amount of light from an incandescent, the LED just uses less energy to do so.

What does that mean? You can get a brighter light with less wattage. Do you have a fixture that you wish was brighter but it is a 60 watt max? Well, with LEDs you can get a bulb that is a 100W lumen equivalent to an incandescent without hitting your max wattage and ruining your fixture.

Are LEDs blue light?

LEDs have a bad reputation for being "blue", and when they were first introduced to the public they did have a blue tint to them. But LED technology has come a long way in a short amount of time and this is no longer the case.

The color of the light is measured in Kelvin; lower numbers produce a warmer light (like incandescent) and the higher the number the whiter or cooler the light (like blue). LEDs are primarily available in two color temperatures; 2700K which is a warm light, like an incandescent bulb, and 3000K which is a whiter more neutral light, like you see with a halogen bulb. Some companies offer higher color temperatures as well, like 3500K or even 4000K if you want an even whiter light.

Technology is constantly advancing to where some even offer a warm dim option. What this means is that as you dim the light down the color of the light will get warmer, like an incandescent bulb.

Color Temperature Scale in Kelvin

What will LEDs do to the color of my room?

This is another bad reputation LEDs have, which was caused by everyone's first impression. When they first came out, they did make colors look different, like blues looked green or reds looked brown. This is because the light coming form the diode was missing sections of the light spectrum.

This has since been addressed by companies producing products according to the Color Rendering Index, or CRI. The CRI measures how accurately a light source renders color on a scale from 0-100, incandescent is 100. Most LEDs today have at least an 80 CRI, but with the constantly improving technology 90 CRI and higher options are becoming available.

Can I put LED in any fixture?

Yes and no. While LED technology has come along way since its beginning, there are still some limitations on what LED bulbs you can get or what bulbs can fit into your existing fixture. Standard sockets such as E26 (medium base) or E12 (candelabra base) are available in many different options. Other bases like small halogen bi-pin bulbs are now available, but many might be too large for your fixture. However, smaller ones are starting to hit the market in the past year.

Unfortunately there are still a few socket sizes out there that do not have a compatible LED bulb, YET.

What does "integrated LED" mean?

Integrated LED lights have the LEDs built into the fixture. They could be on a panel, strip, or disc, which is also called a LED module. The diodes are installed into the fixture, in other words you won't find a socket for a bulb. If there is a malfunction with the LED module, it can usually be replaced.

This is an integrated LED

Is LED dimmable?

While most LED lighting is dimmable, that is not the case with all LED. Lighting plays a very big role in your home, whether you know it or not, so if a fixture is dimmable is very important.

When purchasing an LED fixture check to see if it is dimmable. If it is you will prpbably need a True universal Dimmer, it works with both incandescent and LED bulbs. Most LEDs will work with an ELV dimmer. Some may require a different type so check before you purchase to see if you need a new dimmer.

How long do LEDs really last?

LEDs have a very long life span. LEDs typically have a life span of at least 30,000 hours. But most companies are pushing their technology and extending the life to 50,000 hours or more. A fixture that you use for a few hours a day with an LED bulb can last you 20+ years.

The life of an incandescent is 1,000+ hours, a CFL is 10,000+ hours, and most LEDs are 30,000+ hours.

Modern LED Fixtures Provide Sleek Design and Efficiency

Don’t let the folks at the Thomas Edison House hear this, but the old-fashioned filament lamp, known to most as the incandescent bulb, is on the road to obsolescence.  The Light Emitting Diode (LED) is really beginning to give it a run for its money. Most are familiar with LED from indicator lights on devices and theater aisle lighting. But LED technology has come a long way and now offers lighting designers more options than ever before.

Many consider LED “new” technology, but it has been around for over 50 years. The way they emit light is a relatively complex process of electroluminescence through semiconductor materials. “While it’s a complicated process, the technology has advanced so much recently that we’re really going to see an increase in their use for more home applications than ever,” said Larry Wolfe, Owner of Scorpio Interiors. Wolfe, a licensed architect, has built a career specializing in lighting design and keeps himself up-to-date with the most modern technology and applications. His showroom offers the city’s most extensive collection of contemporary lighting design items.

The new advantages to LED are that the color quality is comparable to incandescent, it’s becoming more affordable, and now they can even be put in fixtures that allow dimming. While the initial cost can seem high it pays you back with its nearly 50,000-hour life compared to 1,000 hour for the traditional incandescent. There are also savings on your energy bill and, depending on the fixture and location, can even save on your air conditioning as they put off very little heat.

Scorpio Interiors is one of the few dealer that represents Modern Forms by WAC Lighting, a manufacturer of fixtures that only uses LED luminaires, the first of its kind. “The unique thing about this line, from a design perspective, is that all the designs are based on the Golden Proportion, a universal principle that describes aesthetically pleasing forms,” said Wolfe. “They combine contemporary design with the efficiency and small size of the LED to creating stunning and sleek designs, some as thin as 7/8 of an inch.”

Another shift in the lighting industry is to the measurement of lumens instead of wattage to describe a bulb’s brightness. Wattage is actually the measurement of energy usage while lumens more accurately describes the amount of light the bulb emits. The FTC now requires packaging to include both measurements so consumers have the ability to compare the efficiency of other types of bulbs like compact fluorescent and LED.

As a result of its use of all LED luminaires, Modern Forms has fixtures that provide greater brightness and are 90% more effective than incandescent lighting because they provide more uniformity, consistency, and a fully saturated color spectrum.
