LEDs are more beneficial than Compact Fluorescent Lamps (CFL) and Metal Halide Lamps in many ways
Energy conservation and saving the environment are hot topics in today’s society. ‘Green’ has become a popular word. By adopting the use of LEDs, local communities and government facilities can reduce the amount of money spent on energy bills and save energy at the same time. The use of LED lights by individual homeowners and private companies is a cost-effective way to save energy and money as well. Using LEDs in public lighting applications have many benefits including energy reduction, longevity, safety, high illumination, and environmentally friendly. For home and office use, replacing traditional lighting (CFL, incandescent, and metal halide lamps) with LEDs is simple. LEDs are high quality, affordable, and will illuminate indoor and outdoor areas with bright and warm lighting for decades.
LEDs are gradually becoming a new trend in many areas of expertise. LEDS are attracting worldwide attention with its features of long life span, environmental friendliness, and high efficiency. Even though the use of LEDs is a relatively new concept for common consumers, many people are paying close attention to the issues of energy conservation and saving the environment. Municipalities of major cities around the globe have already placed the energy saving issue at a national level. LEDs, as a revolutionary fourth generation lighting, is the best choice in supporting the effort in energy conservation.
Research shows that the lighting efficiency of LEDs is one times more than CFLs (usually seen with a spiral design) and its longevity is two times more than metal halide lamps. An LED can save energy of up to 50%, has no flicker, and no ultraviolet radiation.
All fluorescent light, including energy saving CFLs, contains 3 to 5 grams of the hazardous substance of mercury. Research shows that upon breaking a CFL, it would be impossible to remove all of the mercury from the carpet. The mercury will float in the surrounding air for several weeks before it goes away. Even if the consumer follows the guidelines on the operation of fluorescent lighting, breakage of the fluorescent light bulbs can still occur. Once the mercury escapes, it can be inhaled and absorbed through the skin. This makes these bulbs hazardous to the health of humans and animals.
Traditional lighting, such as incandescent, metal halide, HPS, etc., illuminates 360 degrees and part of the light is blocked off by the light source itself. Traditional light bulbs have low lighting efficiency and are not easy to use with different optical designs. The part of light that is shined upwards or trapped by light bulbs is reflected down using reflectors, which its efficiency depends on quality of finish, operating conditions, and ambient temperature. The intensity of light decreases as the quality of the reflector degrades over time. Traditional lighting compared to LEDs has a larger size and has a single source of light. An LED has a smaller size and several sources of light that allows better distribution of light, which shines in a downward direction, and has 55 to 60% of light efficiency. In LEDs, none of the light source is trapped or wasted and so, has a high light efficiency, which can reach up to 85% or more.
Consider the low maintenance costs of LEDs
The energy saving lamps on the market, such as metal halide or parking lot lights, have a shorter life span due to quality and technical issues. They have a life span of about 5,000 hours whereas LEDs can last for 30,000 to 50,000 hours.
Replacement and maintenance costs are not small expenses. Based on a man hour rate of USD $50 per hour and the retail cost of one energy saving lamp is USD $10, then the amount of money saved for replacing lights three times in one year equals to USD $180.
Switching LEDs on and off does not affect its lifespan. The frequent shut off and on of energy saving lamps will turn its filament black and it will break down. Metal halide lamps on average can be switched on and off 3,000 times until the lamp begins to turn black and breaks down.
LED garage lights turn on instantaneously. Metal halide lamps take up to 10 minutes to reach its normal brightness and during this time, it uses a large amount of energy. But, LEDs uses energy at a normal rate. The input voltage of LEDs can be between 90 to 265 volts. But, metal halide lamps will not start even with a input voltage of less than 185 volts and when it goes over 245 volts the power increases by 12%. This requires higher standards for the power lines of metal halide lamps.
The LED heat sink that cools the LED is very important and contributes greatly to the LED longevity, lighting color, and stability. ReneSola has independently developed a heat sink model that is the perfect fit with its LED lamp beads and achieves the best cooling effect. For LEDs at 10,000 hours, light fades at less than 5%. But, for metal halide lamps at 2,000 hours, light fades at 20% and higher. Solar panels can be easily combined with LED lighting to save energy and keeping a green environment.

LED lighting is accepted by many countries around the world for its high efficiency, long life span, and low maintenance costs. Choosing advanced and efficient lighting is the key to reducing maintenance costs. LEDs are suitable for use for home, businesses, and public facilities such as parking lot or garage lights where lighting is needed for 24 hours.
