Solar Skylight: SunTracker brings in more light for more hours than any other daylighting system.
SunTracker uses a state-of-the-art solar powered GPS rotation control system to track the sun with a single mirror that effectively reflects sunlight into the building. The light passes through a thermal barrier, through a light well and a bottom light diffuser to effectively spread the light throughout the building.
The SunTracker tracks the sun from an hour after sunrise to an hour before sunset allowing the end user to turn the lights OFF during daylight hours.
Energy Efficient Lighting
The combination of lumen performance, low operating cost, long life cycle and much lower heat generation is what makes the system so energy and maintenance efficient. The system is warranted for 10 years.
High-end clothing manufacturer Patagonia, for example, installed Ciralight's SunTracker advanced daylighting system to reduce electricity consumption at their distribution center in Reno, Nevada.
The facility's requirements for artificial lighting dropped by two-thirds and operating costs, including for HVAC, fell by a third. The reason is that the spectral content of natural light produces about 2.5 times as many lumens per Btu of cooling load than electric lighting does.
That savings would avoid producing 618,200 pounds of atmosphere-warming carbon dioxide, 1,793 pounds of nitrogen oxides and 1,076 pounds of sulfur dioxide. Sulfur dioxide and nitrogen oxides pollute the air, creating smog. Nitrogen oxides harm the earth's ozone layer.

SOLAR POWERED LEDs - STREET LIGHTS
The market for low energy, highly efficient lighting products is enormous. Worldwide the LED market is estimated at $8 billion and growing at 20% annually. The LED lamp will have five to ten times the life, no mercury, and ultra violet or infrared radiation. It will require significantly lower amount of energy and may be qualified in various incentive programs.
For comparison purposes, an incandescent bulb has an efficiency of 10 lumens per watt. A LED has an output of nearly 80 lumens per watt and is expected to reach 150 lumens per watt in the very near future. It appears Incandescent is the past, CFL is the present and LEDs is the future? With Australia and now Canada banning incandescent bulbs, Compact Fluorescent Lamps (CFL’s) are becoming an important topic considering hazardous materials like Mercury, normally associated with fluorescent technology.
Technology leaders will also have to deal with (1) potential government legislation to tax carbon emissions and (2) incentive-based schemes to conserve energy, improve efficiency, no-emissions etc. to control pollution. Legislation means LEDs will become an even more significant issue to reduce local pollution and emissions of greenhouse gases. And in additions to evaluating various technologies, the incentive programs may need to be evaluated at the same time to make good financial sense for LEDs.
Few reasons to consider using LED’s as an option to Incandescent
SOLAR POWERED LED
Solar lights are immune to power outages and blackouts; there are no wires that thieves or terrorists can cut to darken all lights at once. The systems are dependable, vandal resistant, and have a battery backup.

FOLLOWING INFORMATION IS NEEDED FOR PREPARING A PROPOSAL
LEDs Technology: Light-emitting diodes (LEDs) differ from other light sources, such as incandescent and fluorescent lamps, in the way they generate white light. Unlike incandescent, fluorescent and HID sources, LEDs are near-monochromatic light sources. An individual LED chip emits light in a specific wavelength. This is why LEDs are comparatively so efficient for colored light applications. In traffic lights, for example, LEDs are rapidly replacing the old incandescent + colored filter systems. Using colored filters or lenses is actually a very inefficient way to achieve colored light. For example, a red filter on an incandescent lamp can block 90 percent of the visible light from the lamp. Red LEDs provide the same amount of light for about one-tenth the power (12 watts compared to 120+ watts) and last many times longer. However, to be used as a general light source, "white" light is needed. LEDs are not inherently white light sources.
COMMON LED TYPES & PACKAGES
LEDs come in two basic categories:
Low power LEDs commonly come in 5 mm size, although they are also available in 3 mm and 8 mm sizes. These are fractional wattage devices, typically 0.1 watt, operate at low current (~20 milliamps) and low voltage (3.2 volts DC), and produce a small amount of light, perhaps 2 to 4 lumens.
High power LEDs come in 1-3 watt packages. They are driven at much higher current, typically 350, 700, or 1000 mA, and—with current technology—can produce 40-80 lumens per 1-watt package.
High power LEDs come in many different shapes and sizes. Some current products from the leading LED manufacturers are shown below.
