Actually what amount will LED bulbs honestly save you?

There is a great quantity of evidence pointing to the energy savings of LED bulbs but in contrast they do have a particularly high price tag. Another factor in their benefit is long life and high reliability so how do you evaluate whether they are worth purchasing? If you want to get a correct perspective on the commercials you need to work out the total cost of ownership and use of LED Bulbs and compare this to established incandescent light bulbs.

Total cost of ownership evaluation.

In order to perform this calculation it is prudent firstly, to add the purchase cost for the LED bulb to the working cost for this bulb. Now as LED bulbs will ordinarily last 30 times longer than a traditional light bulb then you then need to add the operating costs and 30 conventional light bulbs.

Candle shaped 3watt LED example.

A cost of 15 pence for every kWhour of electricity used has been assumed for these calculations.
The price of a 3 watt LED candle is approx. £15. The electricity fees over the life span of the LED bulb works out at £13.50. This leaves a total lifetime expense of £28.50.
This LED candle light bulb gives approximately the analogous lumens light output to a 25 watt traditional light bulb. A everyday bulb will have a lifetime of anywhere around1000 hours.
At 30 pence for each candle bulb then the cost of 30 equates to £24. To operate the candle light bulb for 30k hours costs £112.50. For 30000 hours this indicates that the traditional light bulb would have a total operating cost of £136.50.
The answer is a saving of a massive £108 by means of the purchase of the 3w LED candle bulb over the life of the bulb. This means that through the purchase of the LED candle bulb a huge saving of £108 is accrued over it’s lifespan.
I’m sure you will agree that this demonstates the astounding savings you get through using LED bulbs!

MR16 LED comparison for a 3 watt lamp.

The calculation for the 3 watt MR16 uses a similar logic so I will not go through each and every step. As the logic for the assessment for the 3 watt MR16 is identical I will not detail the entire calculation. The major consideration here is that the MR16 LED’s can be selected either as a 48 LED lamp or with high power LED’s. Here we need to accommodate for the difference in purchase expenditure with the 48 LED version costing mostly £10 and the high power version costing usually £15. The high powered LED’s will illuminate with a single or triple beam whereas the 48 LED lamps have 48 different light sources.
The price of the MR16′s is assumed to be 80 pence as with the candles which means that the lifetime savings are;
A saving of £113 is attained through the use of the 48 LED MR16 during its lifetime.
You can easily save £108 through the use of the high powered MR16 LED over their life.
Again the savings are monstrous and only vary by 4.5% across the different variants of LED bulbs.

Architectural Lighting

By Russell Neal

In today’s marketplace, general contractors, electricians and property managers are routinely engaged in competitive bidding on commercial construction and architectural lighting projects. Working with a commercial lighting distributor who specializes in architectural lighting and who represents multiple manufacturers, gives the commercial designer more freedom to bid specific items without fear of limited options, restriction to only one or two manufacturers, or equipment that fails to meet all necessary safety and light pollution regulatory codes.

Architecture lighting specialists will help you carefully balance the major considerations of safety, security, aesthetics, and regulatory code compliance by helping you precisely match fixtures to exact client specifications, and by accessorizing your system to remain as maintenance free and energy efficient as possible. Extensive planning and consultation with a specialist can be obtained at a small, reasonable fee if your team requires assistance with advance planning or ongoing consultation in developing the specifics of your proposal.

Architectural Area Lighting

Architectural area lights are heavily regulated due to their high lumens output and must illuminate only the intended area(s) without generating light pollution that will create a hazard or a nuisance to a nearby business or residence. It is generally advisable that you plan a proposed architectural area lighting system with specific guidance in the following general areas:

1. Parking lot lighting must meet local foot-candle minimums, minimize glare for motorists, and avoid shining lights into adjacent facilities. Working with a source that can accommodate the Spartan preferences of strictly industrial sites and the more decorative needs of municipalities, corporate headquarters, and hospitality clients can go a long way toward impressive line items that can tip a bidding war in your favor.

2. Parking garage lights must be configured in such a way as to balance vertical foot-candle intensity with horizontal foot candle intensity. This often requires working with a specialist who can input the dimensions of your garage into special software to help you determine which lamps, wattage outputs, and light fixture locations are required to achieve optimal, safe lighting levels in your garage.

3. Outdoor building lights must accent architecture without overpowering it. Different buildings may require anything from wall mounted architectural lights, canopy lights, and wall packs in a wide range of size, voltage, wattage, and color options.

4. Security lights of some sort should always be installed whenever architectural patterns vary or diverge and shadows form under eaves, canopies, walkways, or connecting structures can serve as a hiding place for criminal mischief.

Oftentimes, contractors are hired by offices, churches, municipal buildings, institutions, hotels, restaurants, resorts, and country clubs that require a highly customizes architectural lighting system that will speak to all the many considerations that contractors must factor into developing a truly effective outdoor lighting presentation. These clients often have tight budgets both for equipment and for power requirements, so it is necessary as well to have a wide range of line and low voltage options ready to offer the client at the line item level to make the invoice legally compliant with dark sky and foot candle regulations, practical safety and security concerns, decorative needs, and cost effectiveness through reduced power requirements and minimal long-term benefits.

In these situations, both pre-packaged kits and highly specialized architectural lighting equipment can often tip the balance in favor of a truly comprehensive architectural lighting design that goes beyond the basic cornerstone elements of standard configurations.

Sign and Building Edifice Lighting

Sign lighting can set the tone for the entire site’s lighting system and help your clients more effectively brand their facility. Larger buildings that feature the company brand or logo painted on the building wall itself can be lit with specialty edifice lighting fixtures that will highlight colors and lettering without creating light pollution for surrounding areas. Flagpole lights can be installed very cost effectively to showcase a client’s patriotism and keynote an important element of the landscape in general.

Architectural Landscape Lights

Architectural landscape lighting delivers a more robust illumination to larger campuses with a great deal of area between the property line and primary structure(s). Certain landscape features such as waterworks, decorative sculptures, outdoor break facilities, and recreational areas can be highlighted in such a way as to compliment the architecture of the main building.

Some commercial lighting vendors, such as Easy Rack in Houston, Texas, furnish architectural landscape lighting kits and specialized landscape and building exterior lighting fixtures appropriate for more high-end projects such as resort hotels, five star restaurants, country clubs, and outdoor recreational facilities.

Fabulous Crystal Chandelier Designs to die for

By Jo Williams

There is absolutely no denying the beauty of crystal chandeliers. These interior conversation pieces have been delighting the senses since the 17th century. While there are many different types of crystal available today, one crystal stands head and shoulders above the rest. Strass crystal, manufactured by Swarovski, is recognized the world over as the finest crystal known to man. This crystal is first machine cut, and then hand polished and coated with an invisible optical layer, creating a stunning effect. It is these Swarovski crystals that are used every year in the design of the unique Swarovski Crystal Palace Collections. These stunning crystal chandelier designs have been introduced since 2002, with the most recent unveiling occurring in April 2006. Let’s take a look at some of the stunning crystal chandelier designs that have been realized through the years.

Fashion designers Bruno Basso and Christopher Brooke designed a chandelier in 2006 called “Science & Fiction”. The shape of this chandelier was based on the Marie-Therese design, which is identified with the 18th century Empress of Austria. The beautiful Marie-Therese chandelier is noted for its ornate candle arms, and “Science & Fiction” made sure to pay homage to this old standard. The chandelier includes 111 crystals that feature a print of one of a kind design, and it is completed by 32 lit black candles.

Contemporary designer Ferrucio Laviani presented an amazing chandelier in 2005 that he called “Yoga”. He took over 100 crystals of differing pastel shades and enclosed them in a beautiful gold frame. “Yoga” is similar in shape to a standard children’s top, but this is one toy you would not want the children to play with. This marvelous chandelier is lit with halogens, casting off a gentle and hypnotizing glow of colors and crystal texture.

Gaetano Pesce introduced a beautiful chandelier in 2006 which he called “Mediterraneo”. This chandelier is a feast for the senses, as Pesce designed this chandelier in much the same style as a traditional old world chandelier – with a twist. The chandelier consists of 140 crystal strands, each one consisting of 87 Swarovski crystals lit up by LED’s that change the color of the design. In addition, “Mediterraneo” emits certain soothing smells and also changes shape before the viewer’s eyes. This is truly a unique and gorgeous crystal chandelier design.

Chris Levine was the mind behind the chandelier entitled “Vertigo”. This creation has the look and feel of old-time chandeliers similar to those you might see in ballrooms, but “Vertigo” is lit with laser lights throughout the rows of crystals. The result is a visually stunning display of what can be done with beautiful Swarovski crystals.

As evidenced by these original designs, the days of “run-of-the-mill” chandeliers are a thing of the past. As designers continue to experiment with the aesthetic beauty of crystals, the presentations will surely resemble the stunning crystal chandelier designs mentioned in this article. As a result, more and more people are sure to discover the beauty associated with crystal chandeliers.
