What Is This Tool?
This converter transforms values measured in nox, a unit for very low illumination, into lumen per square foot, a common measure for illuminance in lighting design and practical applications.
How to Use This Tool?
- Enter the illumination value in nox into the input field.
- Select nox as the source unit and lumen per square foot as the target unit.
- Click convert to get the equivalent illuminance in lumen/square foot.
Key Features
- Converts nox, a specialized unit for low light levels, into lumen/square foot.
- Browser-based and easy-to-use for quick illumination unit conversions.
- Supports lighting-related contexts such as astronomy, architectural design, and photography.
Examples
- 10 nox equals 0.00092903 lumen/square foot.
- 100 nox equals 0.0092903 lumen/square foot.
Common Use Cases
- Describing very low natural lighting conditions such as moonlight and starlight.
- Planning exterior lighting to minimize stray light for dark-sky preservation.
- Characterizing low-light test settings for optical sensors or imaging equipment.
- Specifying indoor lighting for offices, classrooms, and retail as lumen/square foot.
- Controlling photographic, stage, or display lighting with familiar practical units.
- Managing grow-light intensity in horticulture and museum exhibit illumination.
Tips & Best Practices
- Use the tool for converting specialized low-light units into common lighting measures.
- Apply the conversion primarily when transitioning between scientific and applied lighting contexts.
- Be aware that converted values might be extremely small due to the nox measuring very low illumination.
Limitations
- Conversion outputs are often very small, possibly below typical measurement sensitivities.
- Nox is a largely historical or niche unit, so conversions may be rarely required outside specialized studies.
- Lumen per square foot is intended for practical lighting levels generally higher than nox measurements.
Frequently Asked Questions
- What does the unit nox measure?
- Nox measures extremely low levels of illuminance, equivalent to 1 millilux, often used for night-time or near-dark conditions.
- Why convert nox to lumen per square foot?
- Converting nox to lumen per square foot translates very low illuminance values into a more commonly used lighting unit for practical design and validation purposes.
- Is lumen per square foot the same as foot-candle?
- Yes, lumen per square foot is equivalent to the foot-candle, a standard unit utilized in lighting practice.
Key Terminology
- Nox
- A historical or specialized unit of very low illuminance, equal to 1 millilux.
- Lumen per square foot (lm/ft^2)
- A measure of illuminance representing luminous flux incident on one square foot, also known as foot-candle.
