<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 2rem; color: #1d2623;">Luminaire</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">A complete lighting unit consisted of a light source and driver together with parts to distribute light.</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 2rem; color: #1d2623;">SSL</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">Solid State Lighting. Refers to a type of lighting that uses semiconductor light-emitting diodes (LEDs), organic light-emitting diodes(OLED), or polymer light-emitting diodes (PLED) as sources of illumination.</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 2rem; color: #1d2623;">LED</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">Light Emitting Diode is a semiconductor light source.</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 2rem; color: #1d2623;">OLED</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">Organic Light Emitting Diode is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds which emits light in response to an electric current. This layer of organic semiconductor material is sandwiched between two electrodes. Generally, at least one of these electrodes is transparent.</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 2rem; color: #1d2623;">Lm</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">Luminous flux (lumen). the basic unit used to measure the flow of light in the SI system, equal to the amount of light emitted through a solid angle of one steradian by a light source with the intensity of one candela (0.0015 watt)</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 2rem; color: #1d2623;">Cd</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">Is the SI base unit of luminous intensity; that is, power emitted by a light source in a particular direction. A common candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured.</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 2rem; color: #1d2623;">Watt</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">Is a derived unit of power in the International System of Units (SI)</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 2rem; color: #1d2623;">Efficacy - Lm/Watt</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">Luminous efficacy is a figure of merit for light sources. It is the ratio of luminous flux (in lumens) to power (usually measured in watts).</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 2rem; color: #1d2623;">CCT</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">Color correlated temperature is the color temperature of a black body radiator which to human color perception most closely matches the light from the lamp. Color temperature is a characteristic of visible light that has important applications in lighting, photography, videography, publishing, manufacturing, astrophysics, and other fields.<br />The eight ANSI defined MacAdam ellipses (2700k, 3000k, 3500k, 4000k, 4500k, 5000k, 5700k, and 6500k)<br /> <br />There are also:<br />Amber or "Wide life", Tunable white that has controllable range from warmer to cooler CCTs RGB - color changing or color tunable light based on tree colors Red, Green and Blue RGBW - that adds white component to RGB system RGBY - with Yellow component to accentuate orange and yellow colors, that otherwise are not easily achievable with standard RGB.<br /> <br />Warm dimming LED - contrary to standard LED which keeps practically the same CCT when dimmed, the warm dimming simulates incandescent lamp when dimmed down, by warming light - changing CCT from usually 3000K or 3500K or 4000K to less than 2400K.</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">&nbsp;</div>

<div style="font-size: 2rem; color: #1d2623;">CRI</div>
<div style="font-size: 2rem; color: #1d2623;">&nbsp;</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">Color rendering index, or CRI, is a measure of the quality of color light, devised by the International Commission on Illumination (CIE). It generally ranges from zero for a source like a low-pressure sodium vapor lamp, which is monochromatic, to one hundred, for a source like an incandescent light bulb, which emits essentially blackbody radiation.</div>
<div style="font-size: 1.3rem; color: #6c7c7b;">It is related to color temperature, in that the CRI measures for a pair of light sources can only be compared if they have the same color temperature. The highest attainable CRI is 100. Lamps with CRIs above 70 are typically used in office and living environments. LED source 80 CRI minimum (indoor).</div>

The method restricts which values can be used in the calculation based on the sample size, number of hours and intervals tested, and test suite temperature. It also limits the extrapolation for max hours to 6X the hours tested.</div>
