Light Pie 4+

Lighting calculations and all supporting theory in the palm of your hand!

Lighting calculations made easy!

As with all our Apps this App provides the underlying maths and theory behind the calculations together with worked examples. This will allow you to not just get an answer, but more more importantly, to understand how the answer was derived.

Light Pie is written to allow you to undertake fundamental lighting calculations with ease. The following three features are available within the App:

Foot-candle Lux:

Upon entering an illuminance level in either Lux or Foot-candles this feature converts the provided value into its corresponding Lux or Foot-candle value.

Installation Lifetime:

Upon entering the luminaire or lamp life together with the installation’s annual operating hours this feature will calculate the installations lifespan, i.e. the time from new until either relamping or new luminaires are required.

Lumen Method:

Upon entering the required illuminance, room area, average luminous flux of the lamp, luminaire utilisation factor, and luminaire maintenance factor, this feature calculates the number of luminaires needed to achieve the required illuminance.

Room Index:

Upon entering the room length, room width, and the luminaries height above the working plane, this feature calculates the Room Index (K).

Maintenance FactorRoom Index:

Upon entering the Lamp Lumens Maintenance Factor (LLMF), the Lamp Survival Factor (LSF), Luminaire Maintenance Factor (LMF), and Room Surface Maintenance Factor (RSMF), this feature calculates the lighting installation Maintenance Factor (MF).
