Photometric Testing Data and IES File Downloads
We believe in quality, education, and transparency with everything we do.
The good thing about light quality is that it's measurable.
How do Flexfire LEDs make the highest quality LED strip light?
Photometric Test Sheet Downloads
Below you can download comprehensive photometric test results for each LED strip light. The strips are tested using a goniophotometer to measure lumen output, efficacy, correlated color temperature (CCT), color rendering index (CRI), and light distribution patterns, providing complete performance data.
- Lumen output (lm): Unit of measurement for light brightness. It helps you choose the right LED strip for your needs.
- Watts or Wattage (W): It’s a unit that measures power consumption—how much electricity your LED strips will use. The higher the number, the more energy they need.
- Luminous Efficacy (lm/W): A measure of how well a light turns energy into brightness. It’s calculated by dividing brightness levels by the wattage (power) used.
- Luminous Intensity Distribution Diagram: A graphic representation that shows how a luminaire's light is distributed in different directions. In other words, it determines the angle of an emitted beam of light.
- Isocandela Diagram: Graphic representation of the light intensity (candela) distribution of your LED lights in different directions.
- Cone Diagram: It shows how many foot-candles (brightness measured on a surface) will be emitted from the LED strip at a specific distance, for example, one (1) meter.
- Color Rendering Index (CRI): A measurement of color rendering based on 8 color samples. It's how true-to-life colors appear under your LED lights. It’s rated on a scale from 0 to 100: 80+ is standard in most uses, while 90+ is ideal when color accuracy is key.
- Fidelity Index (TM-30): It's also a measurement of color rendering, but it's measured using 99 different colors to check for color accuracy. The higher the score, the more true-to-life the colors look.
- Gamut Index (TM-30): A measurement of color saturation. It tells how intense the colors will look under your LED lights.
- Color Vector Graphic (TM-30): It's a graphic representation of how saturated or desaturated colors will appear under your LED lights and whether there is a hue shift in any of the 16 color bins.
- Color Quality Scale (CQS): A way to measure how well a light brings out colors, using 15 highly saturated colors. It helps assess how accurately and pleasantly colors appear under your LED lights.
