Convert illuminance in lux to luminous intensity in candela (cd), based on the distance from the source.
Formula:
Candela (cd) = Lux × Distance²The Lux to Candela Calculator is an essential tool for converting illuminance (lux) to luminous intensity (candela). Whether you're designing lighting systems, evaluating beam intensity, or working in photography or theater lighting, understanding the relationship between lux and candela is crucial.
Lux (lx) is a unit of illuminance. It measures how much luminous flux is spread over a given area. One lux is equal to one lumen per square meter. Lux tells you how brightly an area is lit.
Candela (cd) is the SI base unit of luminous intensity. It represents how much light is emitted in a particular direction. It’s commonly used for measuring focused light sources like LEDs, laser beams, and flashlights.
Converting lux to candela helps in:
The mathematical formula to convert lux to candela depends on the distance from the light source:
Candela = Lux × (Distance)2Where:
If the illuminance is 100 lux at 2 meters from a light source:
Candela = 100 × (2)2 = 100 × 4 = 400 cdHere’s how professionals use lux to candela conversions in different fields:
| Lux | Distance (m) | Candela |
|---|---|---|
| 50 | 1 | 50 |
| 50 | 2 | 200 |
| 100 | 1.5 | 225 |
| 200 | 3 | 1800 |
No. The conversion requires distance in meters from the light source to the illuminated surface. Without that, you can’t accurately determine candela.
Yes. For more accurate real-world calculations, the beam angle of the light source should be considered, especially when designing spotlights or directional lighting. However, for basic lux-to-candela conversion, only the lux and distance are needed.
The Lux to Candela Calculator is a powerful resource for lighting designers, engineers, photographers, and hobbyists. By simply inputting the lux and distance, you get accurate candela readings, allowing you to make smarter lighting decisions for energy efficiency, safety, and visual comfort.

It’s important to note that several factors can affect your lux to candela calculations:
If your target is to meet specific candela requirements for safety or design purposes, reverse engineering from lux values using this calculator is effective. You can adjust light intensity, beam focus, and fixture placement to achieve desired candela levels.
Lighting manufacturers and product engineers often use lux to candela calculations in the design phase of devices like:
Accurate light intensity predictions help reduce energy consumption, improve safety, and ensure compliance with lighting standards.
