High-CRI LED lighting is a light-emitting diode (LED) lighting source that offers a high color rendering index (CRI). CRI is a quantitative measure of a light's ability to reproduce the colors of objects faithfully in comparison with an ideal or natural light source.
The useful daylight illuminance calculation is based on three factors—the percentage of time a point is below, between, or above an illuminance value. The range for these factors is typically 100–2,000 lux. Useful daylight illuminance is similar to daylight autonomy but has the added benefit of addressing glare and thermal discomfort. [44]
Photoflood lamps are a type of incandescent light bulb designed for use as a continuous light source for photographic lighting. [1] The filaments of such lamps are operated at much higher temperatures than is the case for standard, general lighting service lamps. The result is a brilliance of light much higher than the lamp's wattage rating ...
A floodlight is a broad-beamed, high-intensity artificial light. It can provide functional area lighting [ 1 ] for travel-ways, parking, entrances, work areas, and sporting venues to enable visibility adequate for safe task performance, ornamental lighting for advertising, façades, monuments, or support perimeter security.

Calculating daylight factors requires complex repetition of calculations and thus is generally undertaken using a complex software product such as Radiance. This is a suite of tools for performing lighting simulation , which includes a renderer as well as many other tools for measuring simulated light levels.
