For instance, a single 10-watt LED that puts out 800 lumens of light (lumens are units of brightness for a light source -- more on that in just a bit) will add about $1.20 per year to your power
A high CRI number is like a high grade point average for color quality. While most LEDs score in the 80s (a solid B average), both the Cree TW Series and the GE Reveal LEDs score in the 90s
At zero (0), all colors look the same. A CRI of 100 shows the true colors of the object. Most LED lights produce a score of about 80-90 on the chart. The result is a brighter room, but with a much more natural, accurate output of light. As a rule, a CRI of 90+ is considered excellent, and anything below 80 is considered mid-range to low.

Incandescent lights have the worst lifespan of any bulb on the market (roughly 1,200 hours). Typical lifespan values for an HID bulbs like HPS or CFL are around 10,000-24,000 hours (10-20 times as long). LEDs last 2-10 times as long as HID bulbs which means they last roughly 50-100 times as long as incandescent.
The difference between CRI and CCT explained. As explained above, CCT and CRI measure two different aspects of color. CCT tells us the color of the light emitted by the light bulb, and is immediately visible to the casual observer by looking directly at the light source. On the other hand, the CRI value does not tell us the color of the light
Color Rendering Index (CRI) describes a light source's ability to reveal an objects' colors as they would appear under natural light. An LED bulb with a low CRI value (less than 80) would cause colors to appear quite different from how they would appear under natural light, while another LED bulb with a high CRI value (95 or higher) would show
In short, a non-incandescent bulb (e.g. an LED A19 bulb) with a 2700K color temperature rating, will have a light color similar to an incandescent bulb. If you like the color of the traditional incandescent bulb, 2700K is the color temperature you need. 2700K provides a very nice and warm atmosphere, and is a great choice for living rooms and
3000K or 4000K for a Kitchen. Both 3000K and 4000K are suitable for kitchens. 3000K is slightly more yellow and 4000K will start to be more cool. Kitchens typically need a bright light with cool tones. That said, 4000K would be preferred in most kitchens. Pay attention to your kitchen design.
For example, a 9 watt LED bulb and a 60 watt incandescent bulb will both produce the same lumen output. Most LED light bulbs will also be labeled with the wattage equivalent for easy comparison. Color Rendering Index (CRI) CRI is a measurement of how light affects the appearance of color.

The Color Rendering Index (CRI) is a scale from 0 to 100 percent indicating how accurate a “given” light source is at rendering color when compared to a “reference” light source. The higher the CRI, the better the color rendering ability. When digitizing negative film with a digital camera, having a high CRI light source is VERY important.
Featuring 120 LED beads this palm-sized panel kicks out an impressive 1580Lux (which you can dial down to avoid blinding your subject). If you’re shooting with a group then you can promote a friend to the role of ‘light stand’ and get them to position the light to illuminate your subject while you focus on directing and composition.
The CRI ratings cast a huge impact on the way lighting appears. You can clearly see the stark difference between the luminance levels of lights with different CRI ratings. Higher CRI ratings of any light denote a better color rendition that makes the color, details, and texture of the object clearly discernible to the human eye.
Typically, LED lights have a CRI rating between 70 to 98. We suggest going for LED panels with 95+ CRI if you want to light for camera work. Though they’re a bit expensive, the results are stunning. In residential and commercial use, 70-85 CRI works perfectly. You can learn more about the color rendering index (CRI) here.
