The main advantage of LED lighting is efficiency. In standard incandescent bulbs, the light-production process involves generating a lot of heat (the filament must be warmed). This is completely wasted energy, unless you’re using the bulb as a heater, because a huge portion of the available electricity isn’t going toward producing visible light. LEDs generate very little heat, relatively speaking. A much higher percentage of the electrical power is going directly to generating light, which cuts down on the electricity demands considerably.
• Use 36%- 74% less energy and are greater than 96% recyclable
• Last 50,000-125,000 hours with more even, cleaner light that stays bright longer
• Advance your company’s Green Business Rating
• Do not contain Mercury or any other toxic heavy metals
• Operate much cooler than traditional fluorescent and incandescent lighting, lower AC costs
• Are Instant On, Instant Off – no waiting for warm-ups or annoying flickering
• LEDs run quiet – no noisy ballast hum!
• Do not emit UV light or radiation, making them food safe
• Are excellent for cold temperature storage
LED lamps have several advantages over conventional incandescent bulbs. For one thing, they don’t have a filament that will burn out, so they last much longer. Additionally, their small plastic housing makes them a lot more durable. They also fit more easily into modern electronic circuits.
While all diodes release light, most don’t do it very effectively. In an ordinary diode, the semiconductor material itself ends up absorbing a lot of the light energy. LEDs are specially constructed to release a large number of photons outward. Additionally, they are housed in a plastic lens that concentrates the light in a particular direction. As you can see in the diagram, most of the light from the diode bounces off the sides of the bulb, traveling on through the rounded end.
Per-watt, LEDs output more lumens of light than regular incandescent bulbs. Light emitting diodes have a higher luminous efficacy (how efficiently electricity is converted to visible light) than incandescents — for example, Titan LED’s LED tube lamp produces over 100 lumens per watt compared to an incandescent bulb’s 17 lm/W. And they last: LEDs can have lifetimes of 50,000 hours or more [source: Design Recycle Inc]. Many Titan LED lighting products are rated for 90,000- 125,000 hours and come with all inclusive 5 year and 6 year warranties!
Up until recently, LEDs were too expensive to use for most lighting applications because they’re built around advanced semiconductor material. The price of semiconductor devices has plummeted since the year 2000, however, making LEDs a more cost-effective lighting option for a wide range of situations. While they may be more expensive than incandescent lights up front, their lower cost in the long run can make them a better buy. Several companies have begun selling LED light lamps designed to compete with incandescent and compact fluorescent bulbs that promise to deliver long lives of bright light and amazing energy efficiency.
