A trio of environmentally-friendly artists, Jack Sanders, Robert Gay, and Butch Anthony have created a temporary public artwork in Rosslyn

Through Sept 1, 2007. The project, titled CO2LED, is erected in a the traffic island at near the Iwo Jima memorial. On display through Labor Day, CO2LED celebrates environmental stewardship and beckons the way to the second annual Planet Arlington World Music Festival.

552 solar-powered LEDs (light-emitting diodes) secured to rods of varying heights, each topped with a reused plastic drink bottle, illuminate the traffic island in an unmistakably beautiful way. The poles' slight flexibility, combined with the LEDs' nebulous glow underneath the ridged surfaces of the plastic drink bottles, create a soft, undulating cloud of light. A native American prairie grass, little bluestem, is planted beneath the poles and stands in contrast to the grid upon which the poles are installed.

At the end of the exhibit I hope someone finds a way to preserve this inspiring use of solar energy.

How to Choose the Right Light Bulb

Until recently, most of us have used the incandescent lighting, which renders the color of objects more closely to that of natural light, in our homes. Fluorescent light was harsh and cold and typically used in offices.

Light is categorized by its color rendering index, or CRI for short, and its color temperature.  CRI is how a light source, a bulb, causes the color of an object to appear to our eye and how well variations in color and shade are duplicated in comparison to natural light.

The CRI number is a rating from 0 to 100, the higher the CRI number the better the color. An incandescent bulb has a CRI of 100. Fluorescent lights can have CRIs of anywhere from 50% to 99%.

Color temperature is expressed on the Kelvin scale (K) is the color appearance of the bulb and the light it produces.

The color temperature of lamps makes them visually “warm,” “neutral” or “cool” light sources. The lower the temperature (2700-3000K) , the warmer the source, yellow-red colors. The higher the temperature(5000K) the cooler the source, green-blue color range.

How this all applies to us when we go to buy light bulbs at Home Depot is that  we generally want light that will  give us the best color rendering, a high CRI number, usually with a neutral or warm color temperature, a lower Kelvin number.

Originally these parameters’ were only met by incandescent lighting, but that is not the case anymore. The compact fluorescent bulbs available today have CRI numbers and light quality that closely matches that of incandescent bulbs. Although compact fluorescent light (CFL) bulbs tend to be more expensive they convert electricity into light much more efficiently than incandescent. The lower energy cost of the CFL can offset the higher cost of the bulb. Compared to incandescent bulbs,  fluorescent bulbs use less power for the same amount of light and usually last longer

An article in Wikipedia states that  ” In the United States, a compact fluorescent light  can save over $30 dollars in electricity costs over the bulb’s life time compared to an incandescent bulb and save 2,000 times its own weight in green house gasses. ”

Many compact fluorescents are designed to replace incandescent bulbs and can fit into most existing fixtures.

A problem with compact fluorescents bulbs is that they are made with a small amount of mercury. This mercury  requires that they be disposed through a hazardous waste disposal program, they cannot be put in the regular trash.

Another type of light is the LED. The LED appears to be the bulb of the future. Although expensive LED bulbs can produce light that is comparable to incandescent.

LED (Light Emitting Diode) last longer that compact fluorescents, they use less energy than traditional bulbs and potentially, compact fluorescents. LED lights are made in all sizes and shapes. LEDs do not contain mercury so their disposal is not a problem.

An article in the New York Times quotes Charles F. Jerabek, the president and chief executive of Osram Sylvania, a unit of Siemans as stating “In the US 78 percent of the public is completely unaware that traditional light bulbs will be phased out in 2012.”

As we all konw that light bulbs should be more energy efficient, and incandescent bulbs will be a thing of the past.

   

High Power LED Light Bulbs

LEDs are better! Light bulbs with high power LEDs provide long life. Light bulbs made with LEDs offer clean pure white light and great colors! LED light bulbs are shock and vibration resistant, and LED bulbs are direct screw-in replacements.
Please do yourself some good by reading the information we have provided here on high power medium Edison base LED bulbs to help you with selection of proper bulbs for the specific use they are intended for. The information will also tell you what kind of LED bulbs we offer, how the LED bulb you want operates with respect to light generated and how it is generated. Without this information, you will not know what LED bulb to buy, or if what you want to buy is the right LED bulb for you.

The color swatches are shown to give you an idea of what the white light color differences look like. They are NOT the actual light colors you will see.


High power LED Bulbs utilize the latest LED technology. These are the surface mount type or SMD LEDs. Small as they are, they generate high heat which must be dissipated or moved away from the LED in order for the LED to live the expected life time of 50,000 hours. To do that, most manufacturers have incorporated an aluminum body with fins to increase the total area that the heat can escape to and be dissipated. The higher the operating current, the higher the heat load to be dissipated. That means more fins, or more thin and longer fins are required. In the case of one newly developed design, the LED bulb incorporates water to assist with the dissipation of heat.

Heat is the enemy of a LED. It can tolerate only what the manufacturer builds into it. Without the means to dissipate the heat created by the actual operating current applied to the LED to generate light, the LEDs will die a premature death. The high powered LED bulbs will have currents of 350-700mA plus running through them. Its a small amount compared to a standard light bulb. But, it is applied to a tiny piece no larger than 5/16" in diameter. This small section of material must take on 350-700mA which is huge for its size. This why so much heat is generated from so little electricity. There is no place for the current to go back to or to run to.

View Angle. The high powered LED bulbs are offered within 10?to 60?and wider beam width or view angle of the LED. The total volume of light between a 20 degree view angle and a 60 degree view angle LED bulb is the same. But, the concentration of light with a narrower 20 degree view angle LED bulb makes them seem brighter because you see all of it in a smaller space. The wider view angle LED bulb will appear much less bright and that is because the same light volume has been spread wide. There is minimal light spread outside of the stated view angle.

Color Temperature.
White LED bulbs will be at 6000k plus (may have a bluish tint).
Daylight White LED bulbs will between 5000 and 5500k.
Cool White LED bulbs will be between 4200k and 4500k Color Temperature.
Warm white LED bulbs will be between 2800k and 3300k Color Temperature.
The larger the number, the colder or bluer tint to the light will be visible.

Standard Medium or E27 base LED bulbs are drop-in replacements for household sockets all over the world. Most of these high powered LED bulbs will operate on dual voltage - 85vac to 260vac making them universally applicable anywhere in the world.

MR16 type LED bulbs fit into two very small diameter holes in a flat socket spaced about 5cm apart. They will not fit into any other size MR socket. The same applies to the MR11 LED bulbs, or other type MR bulb.

The high powered LED bulbs are listed with the watts that the LED is rated to consume. That changes a bit as the electronics also require power and effect the actual watts consumed. But in general, they do not amount to much more than 1 watt total. With that said, we will also state the beam width or LED view angle, how many lumen and watts of light are generated buy these high powered LED bulbs. That is all the number information we will provide as any more than that confuses the subject of light volume or brightness.

Warranty. ALL high powered LED bulbs have a 1 year warranty against defect. Defect does not include or mean excessive voltage coverage. Dual voltage means the bulb will switch internally from 110/120vac to 220/240vac as is appropriate for the country it is used in. Voltage way above 130vac will still have the potential to burn out the LED.
