Lighting That Reduces Guesswork

摘要

These lighting products are essentially staple LED lamps and luminaires that enable performance parameters to be simply adjusted in the field during installation. For indoor lighting, this is typically either light output or correlated color temperature (CCT) and light output, although some products also offer a selection of light distribution. For outdoor lighting, it typically involves light output, but it may also include other parameters such as CCT. As a result, a field-adjustable LED trof-fer might be available with a choice of low (3,350), medium (3,850) and high (4,350) lumen output with an associated range of wattages and a choice of 3.500K, 4.000K and 5.000K CCTs. A floodlight might offer a choice of three lumen outputs from around 5,500 to 11,000 lumens, choice of CCT from 3.000K to 5.000K and an integral photocell field-selectable as on or off.
