How to Choose the Right LED Area Lights
LED Area Lights are ideal for outdoor areas including streets, roadways, parking lots, and pedestrian areas. Well-designed LED outdoor fixtures can provide the required surface illuminance using less energy and with improved uniformity. These LED luminaires also have significantly longer life and offer better lumen maintenance, energy efficiency, durability, color quality, light distribution, thermal management, and low costs.
With new light bulbs, shopping by lumens is more important than shopping by watts when choosing which energy-efficient bulb to purchase. While wattage measures the amount of energy required to light products, lumens measure the amount of light produced. This means that the more lumens the product has, the brighter the light source is. Instead of buying products based on how much energy they consume (watts), consumers should consider how much light they give us (lumens).
Wattage is the measure of the bulb's energy consumption - not how much light it puts out. Energy-efficient bulbs use fewer watts to give off the same amount of brightness (lumens). Because of this, LEDs (which have typically low wattages when compared with lumens) not only help reduce energy usage but also lower electric bills.
Color temperature refers to the color appearance of the light that comes from a light source. It's an important performance characteristic to asses when evaluating bulbs because the color temperature creates the mood of the space you are lighting and can thus influence buying behavior or work performance. The apparent color of a light source is measured in Kelvin. The higher the Kelvin temperature, the whiter the light.
When a fixture is DLC Listed (stands for Design Light Consortium) it may qualify for energy rebates by your local utility which can significantly reduce the cost of ownership. The qualified products list is a resource for program administrators, to help them decide which solid state lighting products to include in their energy efficiency promotions.
