These days, it’s hard to justify not switching to LED lighting; especially for larger projects that require many lights, where the lamps are hard to replace.
The longer life, cheaper initial as well as operating costs, and lower maintenance needs, make LED lighting the ideal choice for most businesses and home owners alike. Below, we explore just some of the many benefits that LED lighting has to offer.
LED Lighting Benefits Advantages, Pros, and Features
LED bulbs fit common lamp fixtures. You needn’t replace your standard light fixtures and lamps to take advantage of LEDs. With almost non existent heat output, LED lights can function in any place designed for a regular incandescent or CFL bulb, so long as the LED light itself physically fits into that space.
LED lighting saves much energy. This 80 to 90 percent less power consumption than incandescent bulbs makes LED bulbs a blessing for aging and under-rated power grids worldwide. By reducing energy consumption by this high extent, we can avoid (or at least delay) costly upgrades to city power distribution circuits. These savings can also reduce dependence on foreign oil and overly rapid depletion of domestic natural resources.
Less temperature sensitive. LED bulbs emit the same amount of light for a given voltage, over a wider range of temperatures than compact fluorescent lamps. This provides vastly more consistent light spectrum output.
Increased reliability. LED light bulbs have come a long way in recent years. The fail less often, last longer, emit a more solid, flicker-free, fuller spectrum light, and more of them these days last as long as or longer, than advertised. They endure better than incandescent lamps and compact fluorescents when frequently switched on and off.
LED lights produce less heat. Since more of the energy they draw is converted into useful, visible light, less is transmuted into wasteful heat. This can lower air-conditioning costs in establishments and homes that replace many incandescent and CFL bulbs with LED lighting units.
Silent operation. LED lighting demonstrates virtually noise free operation. Even when fed from a light dimmer, buzzing, ringing, or whistling of any kind is virtually unheard from most modern day LED bulbs.
Produce less EMI and RFI. The 120 volt LED bulb units feature a series string of individual LED lamps inside. By connecting them in series, the total input voltage required to fully light these lamps increases as more lamps are added. Design with the right lamp count, and you get an integrated lamp unit that operates directly from the 120 volt line; requiring no electrical conditioning except for perhaps, the conversion from AC to DC. Components to accomplish this are simple to arrange, and no switch mode power supply drivers are needed. Thus, less to no electromagnetic and radio frequency interference is generated during normal operation.
LED lighting is getting cheaper. As the LED production technology matures, prices are falling, and you can now buy packs of two or more bulbs for significantly lower prices than buying each lamp separately.
LED lighting technology provide MUCH longer lamp life. Though some LED lights fail before reaching life expectancy, as we’ve experienced in recent years, in theory, LED lamps should outlast incandescent bulbs by several to as much as fifteen times if properly cared for.
LED bulbs come in a wide variety of color choices. Unlike incandescent bulbs, LED lamps are available in just about any color from low red to high blue. E.g. Examples such as the 2700k (warm white), 3000 K (less warm white), 5000 K (cool white), 6500 K (daylight white, which is a sky-blue shade of white), and the deep sort of blue you see in Christmas decoration displays. Manufacturers attempted this with incandescent lamps but never got the colors above 3000 K or so, to work nearly as well. Efficiency and life span of incandescent bulbs drop as you move their color output more toward blue. LEDs are highly efficient however, regardless of color temperature output.
LED lighting offers Instant, full brightness. Whether hot or cold climates, LED lamps illuminate to full brightness instantly upon energizing. No warm up time required, and they provide steady, fluctuation free lighting. Usually no flickering. If you do observe flicker, you may be running a dimmer on a non dimmable LED light. Also, flickering is a sign that the bulb itself may be burning out. This makes LEDs great for outdoor applications such as the headlights in cars, street lighting, and residential porch illumination.
Less long-term brightness reduction. While tungsten deposits accumulate on the inner walls of incandescent lamps over many hours of operation, and cause notable reductions in light output, LED light bulbs suffer far fewer of these difficulties. Typically, they burn nearly as brightly at the end of their lives as at the beginning, although some solarization and other deteriorations of the plastic housing and reflective surfaces may cause noticeable dimming and color changes over time.
Long extinguishing time. Some of today’s LED lighting features an interior phosphor that continues emitting usable light for a few milliseconds after power has been switched off. Then, the output dims down that same way and incandescent bulb does as its filament cools off once turned off. This helps further solidify the light by safeguarding against AC flicker that it so often seen in those old technology fluorescent lamps.
LED lighting is physically and electronically more rugged. No delicate glass tubes to break. LED globes are typically constructed of thick metals and hard plastics, that resist shattering. Also, with less supporting electronics in the 120 volt varieties, LED bulbs tend to fail less frequently than CFLs or incandescent lighting.
More Environmentally Safe. Since LEDs should be recycled, and since appropriate recycling stations have not yet been set up in many market areas, the consumer must store them until such facilities become available. Fortunately however, since LED bulbs contain no hazardous gasses, and since they’re difficult to break accidently, long term storage until neighborhood recycling becomes widely available should pose few if any problems.
Improved even light distribution. Modern LED lamps radiate their light about equally well in all directions (omnidirectional) as candles and incandescent bulbs. Uniform solid state lighting.
Improving LED lighting technology. Over time, efficiencies in LED lighting have risen, in terms of energy consumption as well as initial purchases prices. This trend will likely continue for the foreseeable future. So obsolescence should not occur for at least a decade, and probably more.
