Advantages And Drawbacks Of LED Floodlights


LED Floodlights is a kind of floodlighting fixtures which offer even illumination across a wide space such as the yard, square, stadium, stage or other large areas. Once in a time, metal halide and high pressure sodium are commonly used in for floodlight sources.

Many home owners do not think about putting much into bathroom lighting. Anytime it comes to the living room or kitchen, however, it seems people can never spend enough.

Light Emitting Diode are brought into this area recently due to the quick development of LED manufacturing and packaging. Compared to conventional lighting options, LED has unprecedented benefits which accommodates the requirements for energy-saving and less maintenance.

This article would explain the benefits of LED flood lighting system in detail and some drawbacks will also be mentioned for your quick reference.

Benefits of LED Floodlights:

LED flood lighting, no matter the lamps or the integrated fixtures are compatible to regular flood lamps or fixtures. It indicates that you can buy a LED flood lamps and install it in a short time. Or if you want to use a LED flood light fixture, you simply need remove the old fixture and replace it with the new one simply.

They don't yield too much heat. Due to the lighting mechanism, LEDs have no IR emission, which increases the ambient temperature swiftly. It means less cost for air conditioning. Moreover, there is no dangerous UV radiation and the fixture body maintains at an acceptable temperature due to the high-efficiency of LEDs.

As outlined above, LED is the most efficient lighting source than the ordinary metal halide or high sodium. The lumen per watt record are frequently in labs all over the world. And LEDs in mass production may reach around 90~100 lumen per watt. The value already exceeded that of HPS (High Pressure Sodium) and Metal halide, which was the most efficient light sources formerly.

Long life-cycle is the most amazing benefit of LED lighting. The rated life of LED is about 50,000 hours, which is the period from initial 100% lumen output to 50%. The lifetime is 10~50 times of the ordinary lighting sources. Moreover, LED floodlights use chips that assembled with tens of single LEDs or integrated high energy emitters. There is no impact on the functions if one or several lighting units damage. So it's more robust than other ordinary lamps.

The unique feature of LED allows it to produce different colors readily without filters. This gains an extra energy-saving as there is no waste because of filtering. In addition, LED floodlights are more compact in size and integrative without extra optical fixtures.

Most metal halide lights utilized in the home nowadays are installed where bright light is needed for instance a kitchen or restroom. However if you are intending to make use of this kind of lighting in your house there are certain safeguards that need to be undertaken.

Downsides of LED flood lights

The initial cost is higher than regular lamps. Generally, LED lights are 3~5 times more costly than conventional bulbs. While the operation cost may be much less, as there are much less energy bills, fees of frequent light replacement and labor of maintenance.

LED flood lights are not potent enough for some critical applications that require extra-high lumen. Due to heat sinking limitation, a LED flood light fixtures may not exceed 200 Watts very easily. So it's difficult to reach 10,000 lumens for LED flood lights. In this aspect, HPS or metal halide can reach the goal readily as there is not too much concern of heat dissipation for them.

Among the issues of LED lights, dimmability is one of the latest conflicts still yet to be fully solved. Dimming LEDs is basically easy, because analogue dimming, that is the adjustment of electricity, has long been a preference.

In short, LED flood lighting system can replace conventional lights for floodlights applications in many cases. The new LED technology are the eco friendly solutions that gains in less power intake and less maintenance. The barrier to mass application mainly comes from the high initial cost and limited total lumen output.

Is LED High Bay Light Suitable For You?
LED high bay fixtures can be noticed in houses as well as in lavishly sprawled out places like a sports stadium. Their remarkable technology is a great augury for the future as they are quite unlike the pernicious conventional lights. Their emission rate is remarkably low.

Why LED Lights Are Becoming So Popular
Did you know that Light Emitting Diodes, known as LEDs, are being increasingly used for various lighting applications? The reason for their getting so trendy is their energy efficiency.

Basic Things You Need To Consider When Selecting Appropriate Outdoor Lighting
When choosing the right outdoor flood lights, there are some things you need to consider. Take into account the quality, company, design, energy consumption, maintenance and durability. These are just the basic points you need to consider when buying proper outdoor lighting.

Installing LED Lamps Can Be A Big Contribution Towards Protecting The Environment
Many environment-friendly NGOs are doing their best to protect the environment, while we all are standing still, cheering for them and supporting them verbally. What many don't understand is that everyone of us can collaborate in this movement without being associated with those.

Why You Need To Have LED Lights On Hand
No matter where you live in the world, there's often some risk of disasters or tragedies caused by man or Mother Nature. It could be hurricanes, floods, tornados, train derailments, electricity outages, storms, cyclones, earthquakes, sinkholes or anything else.

Why Customers Are Opting For LED Lights
