## What is Luminous Intensity Conversion?

Luminous intensity measures the power of light emitted in a specific direction, fundamental to lighting design and photometry. Our converter handles modern SI units and historical units still found in specifications.

// Common Luminous Intensity Units Explained

export const Candela (cd)

// The SI base unit of luminous intensity. Originally based on candle flame brightness. A typical candle emits about 1 candela.

export const Lumen per Steradian (lm/sr)

// Equivalent to candela. Shows the relationship between lumens and solid angles.

export const Candlepower (cp)

// Historical unit approximately equal to one candela. Still used in some flashlight specifications.

When to Use This Converter

Our luminous intensity converter is essential for lighting designers specifying fixtures, automotive engineers designing headlights, photography lighting technicians, and anyone working with directional light sources.

## Frequently Asked Questions

01 ### Q: What is the difference between lumens and candelas?

/**

Lumens measure total light output; candelas measure brightness in a specific direction. A focused beam has higher candelas but same lumens as a wide beam.

02 ### Q: How bright are car headlights?

/**

Low beams are typically 20,000-30,000 candelas; high beams can reach 100,000+ candelas for visibility at distance.
