I wanted to post a brief article on LED area site lighting to give an idea of where the concept is at and where it seems to be going. Currently, parking areas and outdoor site lighting is performed mostly with HID lighting. Both Metal Halide and High Pressure Sodium lamps are used. With trying to get average and minimum foot candles for projects, you get a variation in foot candles that can cause areas of too much light, areas with shadowing and even light spillage/trespass. Lighting designer engineers and manufacturer’s have done a good job with HID lighting but have pretty much hit the point where there is not more room for improvement due to the fixture and reflectors can’t get much more efficient with the light distribution.
This is where the power of LED’s comes into play. Sure it’s more energy efficient, but it’s in the ability to control the angle and direction of each LED in the array of an LED fixture that gives the major benefit. Why so? By controlling the angle, the variation of foot candles can be much lower overall than traditional methods and you can then base the lighting levels based on minimums instead the average. With LED site lighting you will get less shadowing, trespass, conserve light, and probably use less fixtures. The color rendering is better as well which is great for security.
The major players that seem to be emerging are Beta, GE, and Kim. Be on the lookout over the next 3 to 4 years in the industrial electrical products market to see more breakthroughs in LED site lighting!

People who enjoy indoor gardening are looking for good, bright light for their plants. In addition, they want light fixtures that are light in weight, yet offer excellent light coverage. All of these great features are available in the UFO LED. Although it looks small and round, rather like an unidentified flying object, this grow light provides amazing light at a cost-effective price.
Roughly the same size as a bread plate, the UFO LED light runs on only eighty watts of electricity yet puts out more bright light than a four-hundred watt high pressure sodium or metal halide lamp. HID, or high intensity discharge, lights, on the other hand, require seventy to eighty percent more electricity to run them at the same light capacity as the UFO LED.
Not only does it use a fraction of the energy that other grow lamps use, but it also runs very cool. This is because the UFO LED comes with three fans built in, so you will not need to purchase air-cooled ducting or reflectors and will dramatically reduce your air conditioning costs as well. A cooler running UFO LED light also ensures that you will not burn your tender plant foliage, a common problem with other types of grow lights.
Your plants will flourish under these small but very powerful lights. A UFO LED provides your indoor garden with eight times the light output that you would normally receive with an HPS or MH grow light. It does this through the use of several one-watt LEDs focused toward your plants, the light spectrums of the UFO LED grow light are in color temperatures and tones that your plants can actually use for photosynthesis. The light specrtrums output by the UFO LED is suitable for all phases of plant growth
With all of this remarkable lighting capacity, it is also encouraging to learn that the UFO LED light will last for eighty thousand and more hours, or the equivalent of seven to ten years of exceptional performance. The coverage area of this light is three feet by three feet, allowing you to grow a wide array of plants in that large growing space.
The UFO LED light is lightweight and very easy to use. It does not require any extra wiring or complicated setup, but can be used in the normal light sockets found in your home or greenhouse. So for high performance for low cost, the UFO LED grow light is a perfect choice. The UFO LED light is the indoor gardener’s best friend!
