Advantages of LED Bulbs
What is the advantage of using LED?
This directional lighting capability reduces wasted light and energy. Unlike incandescent lighting, LEDs don’t “burn out” or fail, they merely dim over time. Quality LEDs have an expected lifespan of Approximately 10000 Hours to 50,000 hours or even longer, depending on the quality of the lamp or fixture.
A Brief analysis about LED Lightings.
Learn why it makes sense to say goodbye to fluorescent, halogen and other technologies.
LEDs have swept the conventional lighting marketplace for a variety of reasons, most notably their extended lifespans, reduced energy consumption and lower maintenance requirements. By 2030, the DOE estimates that LED lighting could save 190 terawatt hours of electricity per year, which equates to a whopping $15 billion. As the purchase price of lamps and fixtures continues to fall, more and more facility managers are looking to upgrade their lighting systems with LEDs, given their many benefits compared to traditional technologies. Following are eight advantages for all store decision makers to consider:
Advantage of LED Bulbs
1 | Energy efficiency
LED lights use about 50 percent less electricity than traditional incandescent, fluorescent and halogen options, resulting in substantial energy cost savings, especially for spaces with lights that are on for extended periods. LEDs also aim light in a specific direction unlike conventional bulbs, which emit light—and heat—in all directions (because LEDs are mounted on a flat surface, they emit light hemispherically rather than spherically). This directional lighting capability reduces wasted light and energy.
2 | Extended life
Unlike incandescent lighting, LEDs don’t “burn out” or fail, they merely dim over time. Quality LEDs have an expected lifespan of 30,000–50,000 hours or even longer, depending on the quality of the lamp or fixture. A typical incandescent bulb lasts only about 1,000 hours; a comparable compact fluorescent lasts 8,000 to 10,000 hours. With a longer operational life, LEDs can reduce labor costs of replacing bulbs in commercial situations, achieving a lower maintenance lighting system.
3 | Cold temperature operation
LEDs love the cold unlike fluorescent lamps. At low temperatures, higher voltage is required to start fluorescent lamps, and luminous flux (the perceived power or intensity of light) is decreased. In contrast, LED performance increases as operating temperatures drop. This makes LEDs a natural fit for refrigerated display cases, freezers and cold storage spaces in addition to outdoor applications such as the parking lot, building perimeter and signage. DOE testing of an LED refrigerated case light measured 5 percent higher efficacy (the efficiency of a light source in lumens per-watt, like miles-per-gallon) at -5°C, compared to operation at 25°C.
4 | Durability
Without filaments or glass enclosures, LEDs are breakage resistant and largely immune to vibrations and other impacts. Traditional lighting is usually contained in a glass or quartz exterior, which can be susceptible to damage. LEDs, on the other hand, tend not to use any glass, instead they are mounted on a circuit board and connected with soldered leads that can be vulnerable to direct impact, but no more so than mobile phones and similar small electronic devices.
5 | Instant on
Most fluorescent and HID lamps do not provide full brightness the moment they’re switched on, with many requiring three minutes or more to reach maximum light output. LEDs come on at 100-percent brightness almost instantly however, and with no re-strike delay. This can be advantageous following a power outage or anytime employees open a building during early morning hours when it is still dark outside.
6 | Rapid cycling
Traditional light sources tend to have a shorter lifespan the more they’re switched on and off, whereas LEDs are unaffected by rapid cycling. In addition to flashing light displays, this capability makes LEDs well suited for use with occupancy or daylight sensors.
7 | Controlability
It can take more than a few dollars to make commercial fluorescent lighting systems dimmable, but LEDs, as semiconductor devices, are inherently compatible with controls. Some LEDs can even be dimmed to 10 percent of light output while most fluorescent lights only reach about 30 percent of full brightness. LEDs also offer continuous, opposed to step-level, dimming (where the shift from 100-to-10-percent light output is smooth and seamless, not tiered).
8 | No IR or UV Emissions
Less than 10 percent of the power used by incandescent lamps is actually converted to visible light; the majority of the power is converted into infrared (IR) or radiated heat. Excessive heat and ultraviolet radiation (UV) presents a burn hazard to people and materials. LEDs emit virtually no IR or UV. Rapid advancements in LED lighting technologies, with more improvements on the horizon, have resulted in lowered costs and increased reliability of LEDs.
LED lighting is currently available in a wide variety of home and industrial products, and the list is growing every year. The rapid development of LED technology leads to more products and improved manufacturing efficiency, which also results in lower prices. Below are some of the most common types of LED products.
Industrial and Commercial Lighting
The high efficiency and directional nature of LEDs makes them ideal for many industrial uses. LEDs are increasingly common in street lights, parking garage lighting, walkway and other outdoor area lighting, refrigerated case lighting, modular lighting, and task lighting.
Kitchen Under-Cabinet Lighting
Because LEDs are small and directional, they are ideal for lighting countertops for cooking and reading recipes. The color can appear more cool or blue than is typically desirable in a kitchen, and there can be some excessive shadowing in some fixtures, so it is important to compare products to find the best fixture for your space.
Recessed down-lights are commonly used in residential kitchens, hallways, and bathrooms, and in a number of office and commercial settings. DOE estimates there are at least 500 million recessed down-lights installed in U.S. homes, and more than 20 million are sold each year. Both CFL and LED technology can decrease down-lights wattage by 75% or more.
LED Replacement Bulbs
With performance improvements and dropping prices, LED lamps can replace 40, 60, and even 75 Watt incandescent bulbs. It’s important to read the Lighting Facts Label to make sure the product is the right brightness and color for the intended location. When chosen carefully, LED replacement products can be an excellent option.
LED Street Lights / Solar Street Lights
LED Street Lights are More convenient than traditional Street Lights. It Gives more Brightest Lights and consumes less power. Low Maintenance required and has long life span. Advanced Sensor Based Street Lights can reduce the requirements of Man power to Manually On or Off the Street Light when needed. But LDR (Light Dependent Resistor) Sensor Based Street LED Lights Automatically On when the sun light goes dark and also It will Turn Off Automatically when there is sufficient light available. It will Save a lots of Power Consumption Cost and Maintenance and Operation Cost Dramatically.
LED Holiday Lights
LEDs consume far less electricity than incandescent bulbs, and decorative LED light strings such as Christmas tree lights are no different. Not only do LED holiday lights consume less electricity, they also have the following advantages:
Safer: LEDs are much cooler than incandescent lights, reducing the risk of combustion or burnt fingers.
Sturdier: LEDs are made with epoxy lenses, not glass, and are much more resistant to breakage.
Longer lasting: The same LED string could still be in use 40 holiday seasons from now.
Easier to install: Up to 25 strings of LEDs can be connected end-to-end without overloading a wall socket.
