Basic things to consider when choosing LED Flood Lights

Flood lights, also known as security lights, offer homeowners a more practical option to incorporating bright exterior lighting to their home exteriors without having to buy very expensive fixtures and numerous bulbs. By strategically installing flood lights, you not only extend the hours which you can use your porch, basketball hoop, or swimming pool, you also dissuade intruders as well as wild animals from entering your home.
 If you are in the process of selecting flood lights for your home, you might be overwhelmed by the wide range of options that are available to you. Having a clear idea of your lighting objective and a thorough knowledge of the various products in the market will enable you to choose the appropriate flood light for your home. Here are some things to consider when buying flood lights:
LED Flood Lights
If you are looking for the most cost efficient exterior security lighting option, go for light emitting diode or LED bulbs. They may cost a bit higher compared to CFLs and other bulb types, but the savings on your electricity bill and their relatively longer lifespan will prove that LEDs offer long term savings. These bulbs consume less energy compared to fluorescent bulbs and have a longer lifespan, lasting as long as 50,000 hours or 46 years, if used 3 hours a day and are kept in good condition. LEDs also produce maximum brightness instantly once the switch is turned on or the sensor is triggered, so there is no delay.
Location
When deciding where to install your flood lights, you will have to remember three things. First, the bulbs should point downward at a 22-degree angle so the flood lights shine brightly on the target without blinding anyone. Second, the light should not be pointed towards a neighboring home as this would not only annoy your neighbors, it can also be taken as an invasion of their privacy. And third, the flood lights should be mounted at least 9 feet from the ground so that it is kept out of reach and to prevent any potential hazards which may be caused by very hot bulbs when touched or tampered.
Motion Sensors
Flood lights with infrared sensors have a 180-degree range of motion, picking up on heat waves when someone or something within this range is in motion. Depending on the sensor, the light will remain active for 1 to 10 minutes and then shut off automatically. This is a great safety feature which also helps save energy in cases when the homeowner forgets to turn the lights off.
Dusk to Dawn Lights
If your primary concern is security, dusk to dawn lights are the best available option for you. These security flood lights automatically turn on once the sun begins to set and off again as the sun rises in the morning. If you do decide to utilize this type of flood lighting, you will need to be extra cautious and consult with your neighbors, making sure that an all-night light would not disturb them in any way.
Finish

Lastly, you will also need to take into consideration the aesthetic features of the flood lights that you will be purchasing. There are many different finishes available. Popular choices include copper, stainless steel, and colored lacquer on top of aluminum. The general rule of thumb is, pick a finish that matches the color or the style of the home.

The incredible rise of the LED

While scientists discovered the phenomenon of electroluminescence — where a material gives off light when an electric current or field is passed through it — more than one hundred years ago, it wasn’t until the 1960s that LEDs as we know them today started to appear. However, 1960s LEDs were a far cry from the ones now used to light houses, streets, television screens, and mobile devices. In fact, it’s only really in the last ten years that LEDs have matured enough to underpin the wide-scale luminescent revolution now taking place. So how do LEDs work, and what’s the story of their rapid rise to prominence?

How LEDs work
LEDs work differently from incandescent or fluorescent lighting. Traditional incandescent lighting works by heating a material up to make it glow. Fluorescent lights use electrical current to make mercury vapor emit ultraviolet (UV) light, which in turn causes a layer of phosphor on the inside of the light tube to glow.
LEDs, on the other hand, contain a piece of semiconductor material made up of two distinct sides – one positive and one negative – known as a p-n junction. The positive side has “holes” in it that catch electrons as an electrical current is passed through the material. When the electrons are driven to fall into the holes, they release energy as light. The color of the light given off depends on the wavelength of energy the electrons release, which is determined by the materials the semiconductor is made of. As a result, the development of different colors of LED is closely tied to materials science and the development of semiconductors that enable ever-shorter wavelengths to be released in a very precise and controlled way.

Where to next?
LED technology has evolved incredibly fast over the last few decades, going from being the standby light on your television to the light behind the display itself. With Haitz’s law continuing to hold, expect to see better, brighter, and more affordable LEDs permeating into every corner of our lives. So the next time you buy a smartphone, computer, TV or bulb, think back to earlier versions that you’ve bought. Marvel at what an incredible difference LEDs have made to the size and power requirements of artificial light in a remarkably short space of time.

How energy efficient are led lights

LEDs can brighten a dimly lit house.
If your living space is short on light fixtures and lamps, you can use LEDs to brighten interiors by selecting a watt equivalency that’s higher than that of the old bulbs, says New Haven lighting designer Mark Loeffler. Many fixtures contain a warning not to use anything higher than a 60-watt bulb because the fixture can’t take the heat higher wattage bulbs generate, and it would therefore be a safety hazard. But there’s no problem using a 100-watt equivalent LED bulb, which is only about 17 watts and therefore well under the safety limit of a 60-watt maximum fixture. You get lower energy bills and also two times more light output (measured in lumens, also labeled on product packaging), possibly saving you from buying expensive new floor lamps or installing additional hard-wired fixtures (at $300 to $800 each).

LED bulbs come in a wide range of colors.
Take a look at the LED packaging to see the product's K ratings. K stands for Kelvin, a measure of “color temperature” (the color of light), and you can find bulbs anywhere from 2,700 to 6,500 Kelvin. In general, bulbs up to 3,000k produce warm (slightly yellow) light that’s relaxing and therefore ideal for general living spaces; bulbs from 3,200k to 4,500k are cool (white) light that’s perfect for workspaces such as kitchens, bathrooms, and garages; anything over 4,600k is considered daylight and is best used for outdoor and security lighting. Another measure of color quality is CRI—color rendering index—which indicates how accurate colors look in the light from the bulb. Make sure LEDs you buy have a CRI of 80 or higher.
