How LED Works
LED stands for Light Emitting Diodes. The diode is a simple semiconductor that has the ability to conduct electrical current. When electric current is applied, electrons are excited and able to recombine with holes within the device. This releases energy in the form of photons and thus produces light.
The LED chip has diodes arranged in arrays with a chemical protective layer placed over the top. The diodes are then placed on a metal plate to help conduct electricity. The chips are then connected to a power source to excite the electrons and produce light. In order to maintain a low temperature, the LED lighting unit employs a heat sink component to dissipate the heat produced by the device into the surrounding air.
LED lighting does not have a filament that will burn out. They also do not get very hot because all of the light is produced completely by the movement of electrons. This means a much higher percentage of electrical power is actually used to generate light rather than heat. Therefore, lights powered by LED chips last much longer and run more efficiently than standard incandescent or fluorescent lighting.
LED based lighting is highly efficient as measured by light output per unit of power input. However, the construction and quality of materials used vary widely and greatly impact the performance capability of the LED light. The Alta LED Chips used by American LED Company are the most reliable on the market...made in the USA with the finest materials.
The copper base plates allow almost one half the thermal resistance as aluminum. This provides a lower junction temperature and longer life. Our unique chip design has a 30% efficiency versus the industry standard of 15%. The LED chips also run cooler than the competition, have a luminance of over 110 Lumens per watt, and last for well over 100,000 hours.
Finally, the incorporation of single chip technology truly sets American LED Company apart from many other manufacturers of LED products. Single Chip LED offers a more powerful light, a more uniform spread of light, and more reliability when compared to Multiple Chip LED
LEDs have a wide variety of uses. Some applications include automotive lighting, digital electronics, traffic signals, transmission of information from remote controls, television, and just about any other lighting application. Recently, this technology is being used more and more for general lighting purposes. American LED Company specializes in various general lighting applications creating products to serve each of these specific needs. All lights can be manufactured to Kelvin temperature ranges from 3000K to 6500K.
Energy efficient and instant “on/off” time are vital solutions for lighting large spaces. Our selection of high-bay LED lights are perfect for any size warehouse and will save your business money.
Incorporating LED lighting into a retail location gives aesthetic appeal with a variety of colors and light fixture options. Use LEDs to showcase your products with style.

No matter the need, American LED Company has the product to suit your specific application. LED lighting is more efficient, saves money, is versatile in its uses, provides even cool lighting, and is long-lasting. After installing new LED fixtures you will enjoy all these benefits. Contact our sales staff for your personal consultation.
LED lighting runs more efficiently which means it uses less energy and saves you money. The efficiency of this type of lighting allows it to emit more light per watt when compared to incandescent or fluorescent bulbs. For example, a typical 400-watt warehouse high-bay light would be replaced by a 100-watt LED high-bay lighting fixture. That is an instant reduction of 75% in the energy consumed! Please visit the ALC Calculator to see how much your business could potentially save.
In addition, LED lighting fixtures have a lower operating temperature. For instance our 100 watt chips which have a light output of 11,000 Lumens run much cooler (about 120 degrees) when compared to a typical 400 watt metal halide (about 410 degrees) These heat differences when compared to regular lighting will reduce the demand on HVAC systems and therefore result in additional energy savings. An additional benefit includes no need for “warm-up” time for LED lighting...it is instant on and instant off. An investment in high-efficiency LED lighting will pay for itself before you know it!
Sustainable lighting solutions are necessary for continued protection of the environment. LED offers efficient lighting by saving energy, reducing CO2 emissions, and not filling landfills with extra waste. LED is not only the perfect solution for your business, but for the environment as well.
Buildings utilizing LED lighting will require less energy and be less of a burden on the producers of energy.
Consider: A typical 400-watt high-bay light is replaced by a 100-watt LED high-bay light...a reduction of 75% in energy used.
CO2 Emission Reduction
A building’s carbon footprint can have negative environmental impacts when one kilowatt-hour (kWh) of electricity will result in 1.34 pounds (608 grams) of CO2 emission.
Consider: A warehouse using 400-watt high-bay lights versus one using 100-watt LED high-bay light fixtures. If 20 lights were on for 10 hours a day, 80 kWh would be used per day and 29,200 kWh used per year. In one year, the 400-watt high-bay would emit 39,128 pounds (17,748 kg) of CO2. However, in one year the 100-watt high-bay LED would only emit 9,782 pounds (4,437 kg) of CO2. The emission reduction is drastic and the benefit to the environment is clear.
The very long lifetimes and low maintenance of LED lighting means you will replace your bulbs much less often. There are also no chemicals used, like the mercury in fluorescent bulbs for example, that require special disposal methods.
Consider: A standard incandescent bulb has an expected lifespan of 1,000 hours, but an LED lasts at least 100,000 hours and often far beyond that. Think about how many less light bulbs will be trashed when using LED.
Types of Bulbs:
There are many different types of lighting options available. Depending on the lighting source used, there will be varying levels of performance and lighting effects. Here is a brief description of some of the most commonly used bulbs:
Lighting Measurement Terms:
- Wattage - the amount of electricity consumed by a light source
- Lumens - the amount of light that a light source produces
- Efficacy - lumens per watt of a light source
- Footcandles - the amount of light reaching a subject
(1 footcandle = 1 lumen per square foot)
Light is produced when an electric current passes through a filament causing it to glow and thus making light. This is the classic “light bulb” that is readily available and inexpensive. These bulbs emit a warm, yellow-white light in all directions. Incandescent bulbs come in all shapes and sizes with a clear or frosted finish. Mostly used in the home for traditional lamps and recessed lighting.
There are also more specialized incandescents including reflectorized (reflective coating inside bulb reflects light in one direction) and tungsten-halogen (produce a brighter and whiter light than other incandescents). However, this type of lights are less energy efficient than others and best used for task lighting applications.
Light is produced when an electric arc passes between cathodes to excite mercury and other gases producing radiant energy. This radiant heat is then converted to visible light by a phosphor coating. Fluorescents use 1/5 to 1/3 as much energy and can last up to 20 times longer when compared to equivalent incandescents. There are many commercial and residential applications due to the wide selection of sizes available.
Compact Fluorescent Lamps (CFLs) can be used in most types of lighting fixtures and T8 bulbs are commonly used in larger ceiling fixtures. Despite their versatility, one of the major drawbacks of fluorescent bulbs is the disposal process. Because the bulbs contain mercury, proper disposal methods must be followed including finding an approved recycling location. There are also EPA recommendations to be followed if a fluorescent bulb were to break.
High-Intensity Discharge (HID)
Light is produced when an arc passes between cathodes in a pressurized tube causing metallic additives to vaporize. These types of lights are energy efficient and long-lasting. However, they do not produce the most pleasing light colors. Mostly used in high-bay commercial lights and for outdoor security and area lighting in residential places. There are four types of HIDs: Metal Halide, High-Pressure Sodium, Low-Pressure Sodium, and Mercury Vapor.
Light Emitting Diodes (LED)
Light is produced when voltage is applied to negatively charged semiconductors which causes electrons to combine and create a photon (unit of light). Simply put, an LED is a chemical chip embedded in a plastic capsule that is then connected to a power source. Generally, LED is longer lasting and more efficient than any other type of light source.
Currently the most popular use for this type of light are in under cabinet and select types of down lights. LEDs are being used in more and more applications as the technology continues to develop. However, the quality of LED chips is very important because this determines color quality (CRI), energy efficiency, and whether multiple chips are needed to produce a single light bulb. Alta LED chips have a mean CRI of 85, which is much higher than the industry average.
