LEDs are environmentally friendly on many fronts. First, unlike HID (High Intensity Discharge) lamps LEDs contain NO mercury. In addition, some LED luminaires are RoHS (Restriction of Hazardous Substances) compliant and have been designed to provide more than a decade of near maintenance-free service. That means no re-lamping which means no waste.
LEDs began to be used in the lighting industry in the late 1990's typically in aesthetic, effect, or specialty lighting applications, including architectural highlighting. The use of LED luminaires in applications such as street lighting, area lighting, parking structures, security lighting, and even general lighting for interior spaces.
Many people have a bad impression of LED from early versions of the technology in which, yes, the light did tend to have a blue tint to it. But the industry is constantly developing and LEDs are now being designed to meet our expectations for the lighting we’d want in our homes. The color of light produced is measured on the Kelvin scale, where a lower number equates to a warmer light-the higher the number, the whiter, (and, yes, eventually bluer) the light will be.
As we become more attuned to the role lighting plays in our homes, many of us want to make sure fixtures are dimmable, and this has been a concern with LEDs. While most newer LED technology is indeed dimmable, that’s not the case across the board. Before you purchase an LED fixture, make sure to find out if it’s compatible with a dimmer, and be aware that most dimmable LED fixtures will require specific types of dimmers.
LED spotlights output a narrower beam of light, typically less than 45 degrees wide. Most of the light from a spotlight is concentrated onto a relatively small area producing a bright spot. Led floodlights output a wider beam of light, up to 120 degrees, so the light from a floodlight is spread out over a much larger area.
Because the light is more concentrated, a spotlight will appear brighter than a floodlight but only within its narrower beam. A spotlight is more suited to illuminating objects and a floodlight is more suited to illuminating areas.
