Advantages of LED wall-washer lamps compared with traditional lamps
Edit:Zhongshan Lighting Technology Co., Ltd.   PublicDate:2018-04-14

LED Wall Washer Lamphas been there for several years, but until recently prices have become very cheap and the quality of light has improved greatly.

In the past few decades, we have been accustomed to the light bulb, each lamp life of about 1000 hours.

The the 1970s energy crisis and environmental campaign stimulated the development of more energy-saving technologies. But in recent years consumers have begun to touch these energy-saving technologies.
Fluorescent lamps (CFL) first appeared in stores in the mid 1990s, replacing incandescent bulbs as more energy-efficient lights.

Although fluorescent lamps are very energy-efficient, they have been unpopular because of the dim light of fluorescent lamps, which take a while to glow, and contain mercury inside, which needs to be handled more carefully if broken.
Most companies have eliminated fluorescent lamps because of better performance and cheaper led wall-washing lamps.
Now LEDs can emit a full spectrum of colors, and for most people, a good LED bulb emits light that is no different from incandescent bulbs.
How much money can the LED lamp save?
LED bulbs are still much more expensive than incandescent bulbs. A 100-watt incandescent bulb, for example, costs about 0.75 dollars, consumes 0.1 degrees per hour, and lasts about 1000 hours per bulb. By contrast, a 23-watt fluorescent bulb produces a similar mass of light, but costs about 3 dollars, consumes 0.23 watts per hour, and lasts 8,000 hours. To achieve the same level of illumination, 14 watts of LED bulbs are required, costing 6 dollars, 0.014 degrees per hour, and a life of around 25,000 hours.
So, even though the LED bulbs themselves cost more, they live longer and consume less power.
According to the above light bulb calculation, according to each electricity 1 yuan electricity tariff calculation, an LED light bulb use period, the user altogether needs to pay 350 yuan electricity bill. By contrast, the electricity costs of incandescent bulbs at the same time are as high as $2500. Saving 2000 dollars doesn't sound very appealing to consumers, but if you take into account a family may have two bedrooms, a living room, there is a kitchen and a bathroom, at least 5 lights, if all are LED bulbs, then at least save 10,000 yuan, this is not a small number.

Also, LED lamps produce less heat than incandescent bulbs, which can reduce the need for air-conditioning in hot summer months and save a lot of users.
Should we replace the LED bulb?
The answer to the question is clear. Although LED bulbs are relatively expensive, the one-month savings will be enough to offset the cost of electricity.
If you are using fluorescent light now, then do not have to rush to replace, wait until the bulb is dead and replaced more cost-effective.
LED light bulbs can not only help people save the cost of living, more conducive to the environment. The U.S. Department of Energy estimates that 2014 LED lights save about 41 billion kw/h, more than a nuclear power plant output. If all lighting is converted to LEDs, the power saved will be more than 30 times times. The study also shows that led bulbs have a much smaller impact on the environment than incandescent and energy-saving lamps.
Because LED bulbs use less energy and produce less heat, LED bulbs are also safer. Incandescent bulbs produce heat enough to cause fires under certain conditions, while LED bulbs cannot reach such temperatures. LED wash wall lamps made by high-power led, the requirements of waterproof grade in IP65 above is the best, led wash wall lights illuminate light than hard light bar of the light, the area should be wide. LED wash wall lamps are generally used for outdoor landscape lighting, projecting distance of up to 2-50 meters.
