Millicandela to Lumens Calculator
Convert luminous intensity (mcd) to luminous flux (lm) by choosing a beam angle.
How to Convert Millicandela to Lumens
To convert millicandela (mcd) to lumens (lm), you need to consider the light’s beam angle. Lumens measure the total light output, while millicandela measures light intensity in a specific direction. The wider the beam, the more the light spreads out, changing the lumen value.
Millicandela to Lumens Formula
The standard formula for converting millicandela to lumens is:
Lumens = (Millicandela × Beam Angle in Steradians) ÷ 1000
Where the beam angle in steradians is calculated as:
Steradians = 2π × (1 − cos(θ ÷ 2))
Here:
- Millicandela (mcd) = intensity of light
- Beam Angle (θ) = width of the light beam
- 1000 = converts mcd to candelas
Millicandela to Lumens Conversion Chart
Below is a quick reference table for common conversions at a 30° beam angle:
| Millicandela (mcd) | Lumens (lm) |
|---|---|
| 2100 mcd | 1.72 lm |
| 10000 mcd | 8.18 lm |
| 12000 mcd | 9.81 lm |
| 15000 mcd | 12.27 lm |
| 20000 mcd | 16.36 lm |
Note: Values may vary depending on beam angle.
Examples
- 12000 mcd to lumens – With a 30° beam angle, 12000 mcd converts to about 9.81 lumens.
- 2100 mcd to lumens – With the same angle, you get around 1.72 lumens.
- 15000 mcd to lumens – This equals about 12.27 lumens.
- 10000 mcd to lumens – Comes out to roughly 8.18 lumens.
- 20000 mcd to lumens – Works out to 16.36 lumens.
