BulbAmerica Expands its Line of Halogen Mild Bulbs to Give Customers A lot more Alternatives for High Doing Energy Productive Lighting


Brooklyn, NY (PRWEB) December 14, 2010

Are environmentally friendly light bulbs doing consumers more harm than good? In the April/May 2010 issue of Architectural Lighting, Elizabeth Donoff, ALs editor, expressed uneasiness concerning the transition to eco-friendly lighting, stating, What is of greatest concern to me is that this switch in lighting sources can be simplified to an either-or proposition. Donoff observed that the attention and praise that CFL and LED bulbs have earned from the media and the public has forced a steady stream of technologically immature products onto the market while keeping higher performing lighting options from consumers views. One of the most consistently high performing and environmentally friendly light sources are halogen light bulbs, a technology often overlooked amidst demands for new eco-friendly lighting. As Donoff noted, and BulbAmericas lighting experts agree, the adoption of halogen bulbs is a step consumers can take toward home energy efficiency.

Lasting anywhere from 2,000 hours to 12,000 hours, halogen light bulbs achieve life hour ratings significantly better than incandescent bulbs but when compared to CFLs and LEDs underperform. BulbAmericas Lighting experts and industry leaders have found that this underperformance is often exaggerated because consumers have been encouraged to focus too much on how long a bulb lasts rather than its efficiency and disregard what the actual qualities of light of LED and CFL bulbs are. With regard to efficiency, or luminous efficacy (lm/W), halogen bulbs have an efficiency rating of between 10-30lm/W and LED light bulbs a rating of anywhere between 17 lm/W to 49 lm/W. This means that halogen bulbs can perform as well and sometimes better than LED bulbs. Though the efficiency of LED bulbs is promising, studies by consumer advocacy groups have found that there is little performance uniformity among LED bulbs: some are high performing whereas others do not even outperform incandescent bulbs. Though CFLs are more efficient than both halogen and LED bulbs, they use small amounts (1mg 5mg) of mercury, a neurotoxin, and thus present environmental concerns.

So where do halogen bulbs surpass LEDs and CFLs? BulbAmericas lighting experts observed it is in color faithfulness and their breadth of application. With regard to color faithfulness, or the color rendering index (CRI), LEDs and CFLs are inconsistent. A 2009 report by the Pacific Northwest Laboratory for the US Department of Energy found that LED replacement bulbs for directional MR16s and more diffuse light sources like A-shape bulbs had CRI scores at best 85 and at worst below 70. In other words, LED replacement bulbs may not be able to accurately display the colors in your home, restaurant, or store. Though CFLs fare slightly better than LEDs, halogens are by and large the best choice when color is important, such as in spaces like a kitchen or retail environment. BulbAmericas latest halogen bulbs from Philips, GE, Osram, Ushio and others are offered in nearly every shape from candelabra to T3 with CRI scores of 100 or very close to it, meaning that these bulbs portray color identically to daylight colors. Another advantage of halogens over LEDs and CFLs is that halogens produce a versatile light. In low voltage 12v MR16s, halogens can produce a highly focusable light perfect for spot or broader beams, whereas in PAR shapes halogen bulbs are exceptional for flood lighting and general illumination. LEDs have long struggled as general light sources and CFLs are inconsistent as directional light sources. Though LEDs and CFLs may be the longest lasting and most efficient, sometimes they are simply the wrong choice in certain applications and consumers lighting may suffer because of it. Halogens on the other hand are found in nearly all applications from stage & studio lighting to surgical and medical lighting. With respect to LED replacement bulbs, a 2010 report for the US Department of Energy on LED bulbs found that many of them do not correspond to the dimensions of the shapes they are replacing as specified by the American National Standards Institute (ANSI) codes. What this means is that an LED MR16 intended for a specific track lighting fixture may not fit it even though the LED MR16 has the same ANSI letter-code as the bulb it is replacing. Having been around for a long time, halogen bulbs conform to all industry standards and their use will certainly reduce consumers headaches in finding replacement light bulbs that fit their existing fixtures.

Which Energy Saving Light Bulbs are most effective?

There are a large number of different energy saving light bulbs on the market and it can be quite confusing deciding which ones are best for your particular needs. There are halogen, CFL and LED bulbs which all utilise specific technologies that give the products inherent characteristics and energy saving properties. This short and to the point article reviews the variants of energy saving light bulbs on the market to help you to select the appropriate products for your particular needs.

Looking at halogen bulbs

Halogen bulbs are essentially a high technology type of the original incandescent filament light bulb. The halogen energy saving light bulbs save as a rule 25-35% in electricity costs depending on the specific characteristics and have the advantage of being dimmable. Halogen energy saving light bulbs have simple elegant looks and are of a small size which means they have a great looking visual design.
For more innformation take a looks at energy saving light bulbs

Compact Fluorescent Lamps

Compact Fluorescent Lamp- CFL energy saving light bulbs which use a miniaturised type of the fluorescent tube technology are exceedingly efficient saving around 75% in electricity costs. Modern CFL’s shouldn’t suffer from the dullness and flickering issues that were intrinsic in the earliest CFL’s that hit the market. The main disadvantage of the CFL energy saving light bulbs is that its appearance can be poor, particularly where the fluorescent tubes are evident, but there are some very nice looking spherical shaped CFL’s available. One aspect is for certain and that is that the modern CFL is a considerable improvement on its predecessors.

LED bulbs and

Energy Saving Light Bulbs

LED light bulbs are the best type of energy saving light bulbs. With an energy saving of between 75% and 85%, LED’s are likely to offer the best in energy efficiency. LED bulbs have the further benefit of being incredibly eco friendly. Landfill is decreased because LED bulbs have a particularly long life and the carbon foot print is minimised due to the very low electricity consumption. The final aspect is the visual impression because LED energy saving light bulbs have a high technology visual look which it is important to accommodate as part of the interior lighting plan.

A Guide To Tanning Bed Bulbs And Lamps

By Ciara McNamara

Tanning bed lamps are used in every tan bed or suntan lamp. When purchasing new or used tanning beds, look at the lamps. Make sure they are good for tanning and meet FDA guidelines for safety. Another consideration is access. Be sure the lamps are easy to change when needed. Being able to easily perform the maintenance yourself is important when you buy a home bed.

There are differences in lamps used in conventional and high pressure beds. Make sure you are buying the right tanning bed lamps for your bed. They aren’t interchangeable. If purchasing replacement lighting bulbs on the internet, check the make and model of your bed carefully. Make sure the lamps you are buying are made for your bed.

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.

Green Light Know How: Your Guide to Energy-Saving Light Bulbs

It’s human nature. We’re always eager to explore the newest product, especially the ones touted to improve our lives. At the same time, we can be skeptical about new product technologies, and it can be hard to decide what, and whether, to buy. This is certainly the case with energy-saving light bulbs. The Energy Independence and Security Act, passed in December of 2007, started the clock ticking on the end of the inexpensive and reliable incandescent light bulb. While it’s true that a few bulb manufacturers have flirted with the idea of nudging the energy efficiency of Mr. Edison’s classic up enough to meet the law’s requirements, it now appears likely that U.S. consumers will need to convert to 21st century green light bulbs for most uses starting in 2012.

The mainstream media has been full of news about the coming light bulb revolution. In the last week of May alone, both The Wall Street Journal and The New York Times ran high profile articles addressing emerging trends on CFL (Compact Fluorescent Lamps) and LED (Light Emitting Diode) bulbs.

Since they cost more than traditional bulbs, most people buy energy-saving light bulbs for two main reasons: they save money in the long run and they’re better for the environment. Specifically, because green light bulbs use much less energy to produce the same amount of light, they reduce harmful gas emissions from coal-fired power plants (which generate 50% of the electricity used in the United States).

So consumers should immediately replace all their incandescents with energy-saving light bulbs, right? Well, not so fast. With lighting, quality matters especially in our homes where we gather, read, cook, eat, celebrate and entertain. There’s a perception that green light bulbs require sacrificing light quality. Don’t believe it. Many eco-friendly light bulbs cast soft, beautiful light. And no one should feel guilty about not switching out every fixture containing a regular light bulb. Invest first in replacing the bulbs used most frequently. Savings will be bigger and pay back periods shorter with this approach. And truth be told, there are scenarios where the best bulb is the old-fashioned incandescent.

7 Keys to Choosing the Best Green Light Bulbs for Your Home or Office

Choosing from the many energy-saving light bulbs on the market today can be tricky. Gone are the days when all that mattered was bulb wattage and shape.

By keeping these seven simple guidelines in mind, you’ll be on a path to making smart decisions about what to buy to meet your needs for energy-saving light bulbs in this new green age:

1. Pay more, not less – to save money in the long run, your new green light bulbs should be able to last for several thousand hours. If you buy the cheapest ones you can find, the odds are greater that they won’t.

2. Pick your spots – if a fixture is completely enclosed or is lit for less than 15 minutes at a time and less than two hours a day, CFLs are a poor investment. Low energy, mercury-free halogens are available that are worth a look in these situations. Wait until the existing bulb burns out (or hold onto it for later use – see #6).

3. Nobody likes the blues – the bluish light cast by many fluorescent tubes is not appealing to most homeowners. When buying CFLs and LEDs choose “warm white” or “soft white” labels for color that will look pleasingly familiar. Energy-saving light bulbs labeled “cool white,” “natural light,” or “daylight” are blue-hued and best for targeted applications like reading, task lighting and exterior fixtures, not for living areas, atmosphere or accent lighting.

4. Dimming for dummies – most CFL and LED bulbs can’t be used with dimmer switches. Look for green light bulbs that are boldly labeled “dimmable.” And while the industry has made great strides in recent years, most energy-saving light bulbs do not dim as well as traditional incandescent bulbs. However, the big energy savings are compelling for most homeowners. Making the switch to dimmable CFLs or LEDs in a busy family kitchen can be a real money saver, including reduced cooling costs because neither type generates as much heat as incandescents. Last point: the dimmer switch should be compatible with the green light bulbs you buy.

5. Let’s do the twist – spiral or “twister” CFLs are the least expensive type. If these green light bulbs are hidden behind a shade (though not totally enclosed), buying a spiral lamp will cut the payback period versus glass covered CFLs.

6. Stay out of the closet – most closets need short bursts of instantaneous light. This is usually true of powder rooms, basements, attics and garages. Among energy saving light bulbs, CFLs in particular aren’t suited for this purpose. Traditional bulbs (or again, low energy halogens) are best in these scenarios until something better comes along.

7. Innovative, intriguing, expensive – mercury-free LED bulbs are the future of lighting, case closed. These green light bulbs use less electricity than even CFLs and they last 30,000 hours or more. However, current prices per bulb are as high as $100, which means the payback period for most home-based uses is too long to justify the price. If you are curious about this new technology and live in an area with high retail electricity costs, you might consider LED replacement bulbs for one or two fixtures that get a lot of use (6+ hours per day). Re-read Key #1 before you invest in these types of energy-saving light bulbs.

Ignore the Naysayers – Green Light Bulbs Are Here to Stay

One last point: mercury makes CFLs (and fluorescent tubes for that matter) work. Some serious people, including syndicated columnist George Will, say we should avoid energy-saving light bulbs for this reason. We disagree. Coal-fired electricity generation is the largest contributor of mercury to the environment. Through reduced electricity consumption, a single CFL will keep a lot more mercury out of the environment over its lifetime than it contains. Still, releasing any mercury into the environment is a bad idea, so it’s important to recycle CFLs when they stop working. Recycling your used green light bulbs is getting easier all the time. Visit www.lamprecycle.org for resources.

Green light bulbs are here to stay. This is good news for our wallets and our world because the cheapest, cleanest kilowatt of electricity is the one that is never produced in the first place. Become smart enough to buy the right energy-saving light bulbs and don’t look back.

Crystal Glassware and Chandeliers are just Great and represent Crystal That Reflects and Reveals a Truly Well-dressed Table

By Allen Franklin

Choosing crystal glassware and chandeliers

Glass particulars applied in tableware settings are usually grouped as crystal glassware and are applied to identify the drinking vessels of a table setting. Additionally, the nomenclature is used to name objects fabricated from glass. In the catering industry, glassware commonly refers to any drinking vessel, even if it is made from plastic materials such as polycarbonate or polystyrene.

Most retail merchants nowadays extend four typecasts of crystal glassware in their product line-ups, specifically:

Barware beer mugs and pitchers

Crystal high-class processes of crystal glassware such as carafes and flutes

Usual crystal glassware the more general varieties of glasses employed for beer, iced tea, juice, or water

Stemware champagne and wine glasses

Whether a person opts to fuse contrasting characters of crystal glassware or purchase paired lots is purely a affair of personal penchant. Either path, there is no powerful and express rule about merging or not merging glassware in your accumulation. Reckoning on the types of drinks and foods you are planning to attend to, there is crystal glassware obtainable for all occasion. Being mindful of the all case of crystal glassware that you want is supreme when selecting the type of glassware you want for your table.

glassware Market Styles

Barely similar any other consumer industry, there are tried market Vogues to be alert of in the crystal glassware industry as well. Currently, the succeeding 4 Trends are apparent:

Cocktail glasses, whether they are the authoritative edition or vintage cocktail shakers, are advancing in popularity again. These are expended to make ambiance and supply a sense of glamour that stimulates savoring a drink more alike a joyous outcome or function.

Cut crystal manufactured in the 1930s carries on to be an brilliant purchase for gatherers. It is not unusual to notice sets in styles synonymous to the modern day collections. Due to the fact that it is more often second-hand quality rather than prehistoric, you wont have the overly raised cost tag that is attached to antique glassware.

fusing more spruce flairs the older typecasts is an more and more frequent course. For example, the industry has seen an growth in the buying of champagne bowls, both the more modern ones and those constructed in the 1950s. People would commonly exclusively buy champagne flutes in the past.

Bigger red wine glasses that were prevalent everywhere several years back are no longer as favourite as they once were. Individuals are commencing to envision that they can end a bottle of high-priced champagne or wine by filling a couple of these. Additionally, the add up of alcohol an individual can deplete without being affected also numbers into considerateness. Small glasses are hitting in popularity once again.

standard eccentrics of glassware

Although there are various schools of idea about the divergent categories of glassware, the succeeding is a list of the 7 most familiar families in the industry today:

Beer glassware

Coffee mugs

Drinking glasses

Shot glasses

Stemware

Tumblers

Wine glasses

Chandeliers

Crystal Chandeliers

At Last, be mindful of the fact that not all glassware is dishwasher secure and should solely be hand washed in order to manage for it the right way.
