As more individuals become aware of the energy efficiency of LED lighting, the price of such items as LED bulbs will decrease in price. Currently, the price of one LED bulb is substantially higher than the price of incandescent or fluorescent lighting. However, the initial price for LED bulbs would more than pay for itself in the long run. On average, one incandescent 60-watt bulb lasts 1,000 hours whereas one 2-watt LED light bulb lasts 60,000 hours. Therefore, one would need to purchase 60 incandescent bulbs for every one LED light bulb.

Home LED lighting is a cut above the rest when it comes to energy efficiency. As compared to incandescent lighting, LED lighting wins hands down where energy consumption is concerned. For every 60,000 hours of usage, incandescent lighting uses approximately 3,600 kWh of electricity where LED lighting uses 120 kWh. Bottom line: energy efficiency equals a significant cost savings. LED lighting gives off directional light. Therefore, it is useful as a source of light for reading or spotlighting in the home. Its powerful light output also makes it great for outdoor floodlighting and path illumination. LED bulbs are now available that can replace most halogen or fluorescent light bulbs used in the home.

Although LED lighting may not be useful for all home lighting needs, replacing a few bulbs with LED bulbs would have a noticeable affect in the amount of electricity used.

LED light displays are already used in signs and videos in many indoor and outdoor sporting events and concerts. LED video displays and signs are often preferred because of their higher brightness, which is critical when people are viewing a sign or video from a long distance. Added advantages of LED video displays are their capacity to incorporate curves and 3-D design. This makes LED video displays technologically superior to currently available large screen displays. Research and developers in the consumer electronics space are eager to take advantage of this overwhelmingly useful technology in future products.

Other uses for LED lighting include LED flashlights and key chains, automobile taillights and interior lights, and LED based projection televisions. LED lighting is also being used in the military for LED flashlights that work with night-vision goggles, UV-LED canteen water treatment devices and the sterilization of surgical equipment.

With LED lighting being more energy efficient and technologically superior to many other light sources, numerous LED light applications are sure to evolve. Future generations can expect to consider LED lighting as the standard light source for most lighting applications.

Police officers, firemen, soldiers and other public safety professionals that rely on a flashlight regularly, seek out lights that are designed for their specific tasks. Since the late 1990’s, light emitting diode (LED) technology has improved significantly and today if you are looking for a flashlight, you will probably find more models with LEDs than models with older incandescent bulb technology.

Public service professionals have demanded that manufacturers produce flashlights that are brighter and have longer run times. The manufacturers have responded and today you will find flashlights that produce brilliant white light, or other colors if you need it, have runs times from one hour to sixty hours or more and have bulbs that never need to be changed. Some models have batteries that have a shelf life of ten years and some models require no batteries, you just shake or wind up the light and a chemical reaction produces battery power to run the light.

With the focus on emergency preparedness today, a flashlight is an essential piece of equipment in any home emergency kit. It is easy to convince yourself to find a light on a store shelf, spend a few dollars, and throw the flashlight in the kit, check it off the list and move on. However, when you really need that light, it will need to be charged up and ready to go, easily accessible and bright enough to lead you to safety. With all of the technology available today, you owe it to yourself and your family to shop around a bit and find a light that will last for years and be ready in an emergency.

LEDs use much less power than conventional incandescent light bulbs, therefore an LED can run a lot longer on the same size or smaller batteries. LED technology is quite different from incandescent technology in that an LED is a semi-conductor chip. The semi-conductor is made specifically to produce a certain color of light when a current is applied to it. An LED is much more efficient than bulbs and produces 95% light and only 5% heat, the exact opposite of incandescent bulbs. Also there is no filament to break; meaning an LED light is much tougher than an incandescent bulb. LEDs can last for several thousand hours and never burnout and never need to be changed.

When purchasing an LED light you will notice they are usually more expensive than an incandescent light. The cost is related to the quality of the LED in the light. If you are buying an LED light for only a few dollars, you may not be getting LEDs that were designed to produce usable light, but rather they are computer grade LEDs thrown into a flashlight. LEDs were originally designed to be indicator lights, signaling the status of something, usable as an indicator, but not as a primary source of light.

Many low end flashlight manufacturers take these “indicator” LEDs, place multiple LEDs into a light head and call them LED flashlights. By combining several LEDs into the light head the consumer gets misled into the “more must be better” mentality. In reality, there are several of the LEDs in the light to produce a glow bright enough to be considered usable light. These lights are OK for around the house when supplemental light is needed; but, in an emergency when you need a light source to replace all usable light, an LED designed specifically for the job is what you require.

So, know we know LED flashlights are brighter, tougher, more efficient and longer lasting than incandescent flashlights. Do yourself and your family a favor and replace those dead flashlights that are taking up space in your junk drawer. Replace them good quality LED flashlights and you will never find yourself in the dark again.
