It's well known that a bright light deters would-be thieves and ne'er-do-wells, but home dwellers either had to have wiring experience or pay a professional electrician to install outdoor lights until the advent of solar-powered lighting. Today's solar flood lights open up a whole new world of illumination—they're affordable, powerful, and many are a snap to install. In the past few years, the solar flood light market has exploded, with manufacturers offering brighter lights in smaller packages. The best solar flood lights for your home will depend on the size of the area you want to illuminate and whether you want the lights to remain on or if you prefer they come on only when motion is detected. I was also looking for a number of other factors that indicated quality when testing solar flood lights. I carefully inspected each light right out of the package to determine whether it contained durable materials and to see if it was well made. Each was rated on a scale of 0 to 4, with 4 being the best rating.The testing process involved mounting the lights on a non-moving object, such as a building or a tree, and noting how easy it was to install. Again, points were given for straightforward installation and whether all of the supplies needed for installation were included in the package. After the lights were mounted, I tested their various modes—some were strictly dusk-to-dawn models while others featured motion detection. Some were adaptable to either. I noted when the dusk-to-dawn models came on after dark. I tested those with motion sensors by seeing how close I needed to get before the sensors detected my presence and came on.I recorded how long it took for the lights' rechargeable batteries to run out, and I tested all additional functions, including the use of remote controls and on-light adjustments. While solar flood lights are not complex items, they do vary quite a bit in intensity and design. During testing, we experienced sleet and a snowstorm that left the lights covered in a thin layer of ice for almost 48 hours, so I could see whether the inclement weather impacted their performance. After testing, I added up the points for each light and then determined the individual awards depending on their strongest points.

When you're in the market for solar flood lights, you need to look at more than just the price. Expensive doesn't mean better, and cheap doesn't automatically equate with poor quality. Solar security lights consist of several parts, including solar panels, sensors, fixtures and casings. When you want to buy solar flood light, look at what the manufacturer uses in its design and what kind of lumens output it generates. There are three things to look for in the solar panels – type, wattage and size. Amorphous solar panels have the lowest efficiency levels, around 10%, and are used mainly to change low-power electronics (cell phones, for example). The panels are found in inexpensive, lower-power solar lights. Monocrystalline solar panels are the most effective solar panels, with an efficiency range of 15% to 21%. However, they are very costly. Powerful solar lights tend to use monocrystalline solar panels. Polycrystalline solar panels have a 16% cell efficiency and are less expensive to make. What makes these panels different from other panels is that the solar panels come in a dark blue color. The monocrystalline and polycrystalline panels are installed on commercial buildings and houses where large solar systems are desired. These panels have a high cell efficiency and are seen with powerful solar lights. The wattage is the most important solar panel measurement. It demonstrates the amount of power the panel generates when the conditions are right. For instance, a 10W solar panel will produce 10 watt-hours of electricity each hour. The more powerful the light is, the higher the wattage panel needs to be to produce the light. A 1.5-watt solar panel can generate several hundred light lumens; bigger lights need 10 to 20-watt solar panels. A solar panel's size is dependent on the amount of power the light has and the panel's material. Monocrystalline solar panels of a thin-film solar panel design generate the same power amount as it does from the smaller panel. Before you buy solar lights, consider the area it'll be installed in and if it'll get enough sunlight.

Outdoor floodlights are exposed to the elements – wind, rain, snow, ice, etc. Therefore, you must make sure that the lighting is covered in a weatherproof casing. Casings of floodlights comprise primarily two materials – aluminum and plastic. Most high-power floodlights are made with aluminum casings to give the parts inside the best possible protection from the outside elements. Cheaper floodlights use plastic but don't always have the quality protection aluminum does. Manufacturers use durable plastic for their housing to ensure water damage and extreme temperatures. Be sure to do your homework. Even if a manufacturer uses aluminum, it doesn't matter if it will not withstand the elements. An important element to keep in mind when looking at a fixture's durability is its IP rating. The rating shows the amount of protection a fixture has from water and dust. For outdoor solar lights, you want rating protection of IP65.There are several kinds of solar flood lights, such as pole-mounted lights and ground-mounted lights. See what kind of mount is warranted for your area of installation. Some manufacturers offer an option to buy different kinds of mounting hardware. You also want to consider a fixture's cable length – the cable that attaches the fixture to the solar security light. You also need to consider the length of the area the lighting will be installed. If a cord is not long enough, you can buy extension cords. However, the longer the cable is, the more it affects the solar floodlights.

Lumens measure a fixture's light output and indicate how bright the fixture will be. Watts measures the amount of work the electricity does in a second. For instance, 100W of energy can light 100W for 60 minutes. When looking at the brightness of a solar flood light, look more at the lumen rating, not the wattage. Each type of bulb produces different lumens. LEDs are three times more efficient but consume a similar amount of energy that Halogen bulbs produce. Special equipment is necessary to get the lamp's right lumen measurement. However, many manufacturers do not use the tool to get their lumen rating, so the ratings they list aren't always accurate. For not-so-reliable brands, this is particularly important. The average solar-powered floodlight will have a lumen of 300 to 800. Color temperature relates to the color appearance a lamp produces; or the light of color the lamp generates. This measurement is in Kelvins. Solar security lights should have a kelvin rating of 5,000K to 6,500K.

Sensors play an integral role in solar lighting products because they help in battery conservation and turning on the light when it's time. The two important sensors are motion sensors and photosensors. What do they do? As the name implies, the light will turn on when the sensors detect movement around a certain area. There are three typical types of motion detectors – active sensors, passive infrared sensors, and combined sensors. The PIR sensor is usually manufactured in the motion-activated solar light and won't pick up random movements such as windblown objects or tree branches. A prudent feature of a solar floodlight is the photosensor (or the dusk-to-dawn sensor). This sensor detects when the light is fading, and dark is imminent, turning the light on automatically when it reaches the set level of darkness. When the morning comes, the light will turn off, saving energy and battery. If a solar floodlight does not have this sensor, you will have to turn on and off the light automatically. When looking for solar flood light with this sensor, you must do your homework and read the description. If the manufacturer claims it's a dusk-to-dawn light, you can feel assured it's got a photosensor.
