In recent years, many have switched from old incandescent or halogen bulbs to LED, with one main reason being the longer lifespan of this technology. The average lifespan of an LED light is a whopping 50,000 hours, whereas many traditional bulbs only last a few thousand.
The average lifespan of an LED is often rated up to 50,000 hours. This is about 50 times longer than a typical incandescent, 20-25 times longer than a typical halogen and 8-10 times longer than a typical CFL. If used 12 hours a day, an LED rated at 50,000 hours will last more than 11 years.
Most LED bulbs boast a lifespan of up to 50,000 hours, which means that you may not have to splash out on LED replacement bulbs for up to 10 years after your original purchase. Incandescent bulbs and halogen bulbs will probably only last for 1000 - 2000 hours, compared to up to 100,000 hours for dimmable LEDs.
Longevity. LEDs have an unbelievably long expected life-span, compared to both incandescent and fluorescent lights. With an average life-expectancy of some 50,000 hours, LED strip lights will still be burning bright in 17 years' time, long after their traditional counterparts will have expired.
Unlike incandescent light bulbs, LEDs don't produce light using heat. This is part of what makes them so energy efficient. The downside is that their components can be sensitive to overheating, which can cause them to burn out prematurely.
Overheating is one of the reasons a bulb could start a fire, but that is highly unlikely to happen with LED lights. They may feel hot to touch, but they produce light at a significantly lower temperature than other bulbs.
LEDs, however, do not contain a filament and instead illuminate using a semiconductor. So instead of just instantly burning out like traditional bulbs, LED lights age over time and progressively get dimmer until they stop working altogether. This is what we call “lumen degradation” or “LED degradation”.
LEDs use between 25- and 80-percent less energy than incandescent lights. According to the DOE, the annual energy cost of a 60 W incandescent light is $4.80, but the comparable cost of a 12 W LED, providing the same light as a 60 W incandescent light, is $1.00.
LED lights are definitely cheaper than their counterparts. Not only do LED's consume less energy, but the bulbs also use energy more efficiently, which saves a lot of money.
With LED lights, though, they don't necessarily “burn out.” Instead, they fade or dim until they no longer produce enough life for your taste. So, when the light in your home becomes too dim, it's time to replace them.
To put it simply, well-manufactured LED lights are extremely long-lasting and can be left on 24 hours, 7 days a week. This is because, unlike conventional types of light, LEDs produce minimal amounts of heat, which means they are unlikely to overheat or set on fire.
The operating life of a LED is unaffected by turning it on and off. While lifetime is reduced for fluorescent lamps the more often they are switched on and off, there is no negative effect on LED lifetime.
Lighting accounts for around 15% of an average home's electricity use, and the average household saves about $225 in energy costs per year by using LED lighting. if you are still using incandescent light bulbs, switching to energy-efficient lighting is one of the fastest ways to cut your energy bills.
LED clearly is a very energy-efficient technology. Look at other household equipment – say you change your fridge or freezer to an A+ rated appliance. This would save around 20% energy, while LEDs are 10 times more efficient than the bulbs they replace.
The average LED light bulb costs $1.83 per year to operate if it on an average of 5 hours per day. Here's a further breakdown of costs: Cost per hour: $0.001. Cost per day: $0.005.
They Don't Burn Out
LED bulbs don't burn out like regular bulbs, which simply stop working abruptly when they run out of power. Instead, LED bulbs slowly degrade over time. After several years, their brightness dims.
If the LEDs will not light up at all, then this could be down to a faulty power supply. Solution: If you have several power supplies, then try a different power supply onto the same strip to see if this now works. If it does, then you have a faulty power supply and will need a new one.
XED lights are better in terms of spectral contents, power consumption as well as total running life hours. They produce less glares and are clearer under foggy weather. Moreover, the XED lights don't have excess blue emissions like LED lights.
The light from LED bulbs does not create additional heat in a room, but some parts of them can get hot, so be careful when you touch the base around an LED bulb that has been on for a while.
Yes, new technology LED lighting can and will get hot, but when compared to the lighting of the past, temperatures are much safer. The heat from the lighting will also warm your surrounding environment but in comparison to old incandescent lighting, this ambient heat is greatly reduced when using LED lighting.
Yes, it is very safe. And that's because the only demerit that LEDs have is that some of them emit blue light. But: You should also consider the fact that you get exposed to blue light from other sources including sunlight, your smartphones/tablets, computers, TVs and so much more.
Chronic exposure to LED lights can speed up the ageing of retinal tissue, leading to a decline in visual acuity and an increased risk of eye diseases such as age-related macular degeneration (AMD).
Yes, flickering lights can be a warning sign that there is a fire hazard in your home. When lights flicker all over the house and are not associated with a large or major appliance, such as an air conditioner, turning on it could mean that there is an issue with the wiring, which could cause a fire.
