I ran across a company last week called MaxLite. They had some extremely cool new lighting products that could be very applicable to the industrial and commercial electrical supplies market. I want to say upfront that I have not seen any of these products in a working environment, but I have seen the products work in a demo situation.
First, Maxlite has a high lumen CFL (compact fluorescent) for use as a field replacement for metal halide lamps all the way up to 400w (yes, 400w!). How it works is you replace the 175, 250, or 400w HID lamp with the high lumen CFL. The CFL typically seems to run about half the watts as the HID lamp. You bypass the HID ballast inside the ballast housing and, BAM, you have cut your watts in half without replacing the fixture.
Seems to good to be true huh? It seems very intriguing but there are a few things to consider. First, the lamp life is rated around 10,000 hrs. This is pretty low compared to HID or the other option of replacing the entire fixture with 46,000hr T8’s. Also the temperature rating is around 100 or 120 deg F which will be an issue in some areas and applications.
They did a very nice design with an integral heatsink and cooling fan, but be sure to consider the worst case temperature when looking at this. I think this could be a viable option for some circumstances, just be sure to look at all the application angles. T8 and T5 linear high bays or even 320w metal halide with pulse start will probably be a better choice for most applications, but this could be a fit for some.
They also have some other neat products, LED PAR replacements, LED light bars and my favorite…… a 2×4 LED lay-in fixture. This is the first LED 2×4 I have personally seen that works. It is not a bunch of LED’s formed to fit in T8 lamp sockets like some others have tried, it is an actual flat array of LED’s. Also, the profile is very, very slim, which is great for retrofit applications. The light output seemed adequate and the color seemed fine too.
The price is up there for the 2×4 and also the 2×2 (yes, they have a 2×2). They are probably selling in the field for around $600 for a 2×4. I’m not sure how many will be sold at that price, but it is an interesting option for those that are hooked on LED’s. Be sure to check them out or call your local lighting distributor for info.

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!

Light therapy is becoming the most popular skin care treatment, and it seems everyone wants to try it. Why this sudden eagerness ? Because of the many skin concerns it can improve, naturally, without pain or side effects. Results amazes scientists and users who can now own their personal light therapy device that employs the same technology spas and dermatologists are equiped with : Light Emitting Diodes(LED).
If other forms of light therapy are actually used, LED light therapy is associated to skin care. There are mainly two colors associated to light therapy for the skin, because there are principally two skin issues people want to improve : acne and aging. Red light therapy is used for skin healing, thus it is used for both skin concerns. For acne purpose it will help to diminish acne scars for example. If used for anti aging, it will regenerate skin cells. Blue light therapy is used for acne only, the blue light penetrates the skin and kills the P. acne bacteria (Propionibacterium acnes). Acne starts to disappear, and light treatments also prevent future breakouts.
Here are several light therapy benefits :
Minimizes fine lines and wrinkles like crow’s feet
increases collagen and elastin, resulting in a firmer skin
enhances circulation, this brings more nutritional elements resulting in a younger and smoother skin
Improves skin tone
heals sun-damaged skin
Tights pore size
Reduces redness (inflammation caused by acne)
minimizes brown age spots
Balances sebum production
Light therapy is also used, in another form than LEDs such as daylight spectrum, for stress relief, pain relief, affective disorders, mood balancing and more. In the future, light therapy may be used to treat more medical, cosmeceutical, psychological and every day life disorders.

Do you own any LED lights? Chances are you may have more of these highly efficient little light bulbs than you are even aware of. They show up as indicator lights in computer and electronic equipment, appear in flashlights and remote controls, exterior lighting fixtures and even holiday light strands. They are remarkably efficient and durable, which makes them suitable to a significantly wider range of applications than traditional light bulbs. A perfect such solution is obvious in gardening and the use of solar path lighting.
What are LED lights? A simple definition is actually not that easy to provide in brief, but basically LED stands for “light emitting diode” which are small electronic units that light up when electricity passes through them. Traditional light bulbs are radically different from LEDs, as they use a filament inside of the bulb which lights up when an electrical current is completed. Such light bulbs burn out rapidly and generate quite a bit of heat – in fact touching a lit bulb can lead to a burn. LEDs however stay relatively cool to the touch because they do not operate in the same manner, and are actually more like an old-fashioned transistor than a light bulb. What this means is that they use electricity far more affectively than their old-fashioned counter parts, and are far less likely to fail.
What are the benefits of LED lights? Their main benefit is their remarkable efficiency. While they may cost more at the initial point of purchase, LED lights will last for a very long time. They are resistant to blows, dropping and shock, they are relatively unaffected by continual dimming or turning on and off, they are much smaller and provide a wide range of uses. Additionally, they can appear in many colors through a manipulation of their diode and semiconductor materials, which eliminates the needs for special filters or color applications, which in turn greatly reduces the overall cost of the lighting fixtures in which they appear. Additionally, they do not contain the toxic elements and components of other lighting options, including such heavy metals as mercury which frequently appears in fluorescent lights.
How are LEDs used every day? If you take a quick car trip you will see exactly how LEDs are used in “every day” applications – they are in street lights, automobile signals and tail lights, billboards and signs, solar yard lights, exterior lighting such as spotlights on flag poles or strings of Christmas lights, and you may even notice them on security cameras where they are used for night vision purposes.
Clearly LED lights are all around, and their efficiency and ever decreasing costs will continue to make them a popular choice for home, commercial and technological applications.
