- Optimizing plant lighting for horticultural purposes.
- Safety engineering involving illumination measurements.
Tips & Best Practices
- Always verify the unit of your input value before converting.
- Use common units like Lux or Foot-Candle for standard applications.
- Consider the environmental factors since illumination can vary with angle and reflectance.
- For scientific measurements, use smaller units like Microlux or Millilux as needed.
- Apply rounding consistent with industry precision requirements when necessary.
Limitations
- Measured illumination can change depending on angles, surfaces, and light distribution which the conversion does not account for.
- The tool assumes uniform illumination across the measured area.
- Does not support automatic detection or batch conversion of values.
- Conversions rely strictly on exact conversion factors without adjustment for real-world variations.
Frequently Asked Questions
- What units can this converter handle?
- It converts between a variety of illumination units including Lux, Kilolux, Phot, Milliphot, Foot-Candle, Nox, Lambert, Millilux, Microlux, Lumen per Square Meter, and Lumen per Square Foot.
- Is the conversion precise?
- Yes, conversions use exact luminous flux and area conversion factors with optional rounding to suit lighting industry standards.
- Can this tool account for variations in measured illumination due to environment?
- No, the converter assumes uniform illumination and does not consider factors like angle, reflectance, or light distribution.
Key Terminology
- Lux (lx)
- The SI unit for illuminance, representing lumens per square meter.
- Foot-Candle (fc)
- U.S. customary unit equal to one lumen per square foot.
- Phot (ph)
- CGS unit of illuminance equal to 10,000 lux.
- Millilux (mlx)
- One thousandth of a lux, used for measuring low light levels.
- Nox (nx)
- Very low illumination unit equal to one millilux.
