Lumens per Litre (LPL):

Calculation Formula

LPL = Total Lumens / Volume (Litres)

Where:
LPL: Lumens per Litre (the result we calculate)
Total Lumens: The total light output in lumens
Volume (Litres): The volume of the space being lit in litres

Lumens per Litre Calculator Usage Guide

Learn how to use the Lumens per Litre Calculator and understand its applications in various lighting scenarios.

How to Use This Calculator

  1. Enter the total lumens value for your lighting source (this is typically provided by the manufacturer)
  2. Enter the volume of the space you're measuring in litres
  3. Click the "Calculate" button to determine the lumens per litre value
  4. The result will be displayed in lm/L (lumens per litre)

Understanding Lumens per Litre

Lumens per litre (lm/L) is a measure of the light intensity per unit volume. It's particularly useful in:

  • Aquarium lighting: Helps determine if your lighting is sufficient for your fish and plants
  • Grow rooms: Assists in optimizing light for plants while minimizing energy consumption
  • Water treatment: Used in UV sterilizers and other lighting-based water treatment systems

Interpreting Results

The higher the lumens per litre value, the more intense the lighting in the given volume. Different applications have different optimal ranges:

  • Freshwater aquariums: 10-30 lm/L
  • Marine aquariums: 30-60 lm/L
  • Plants (low light): 20-40 lm/L
  • Plants (high light): 50-100 lm/L

Note: These are general guidelines, and specific needs may vary based on your particular setup.
