The formula to calculate the Lumens Per Watt is:
\[ LPW = \frac{L}{W} \]
Where:
Lumens per watt is a measure of the efficiency of a light source. It indicates how much light (in lumens) is produced for each watt of electricity consumed. Higher lumens per watt values indicate more efficient lighting, as more light is produced with less energy. This is an important metric when comparing different lighting options, especially for energy-saving purposes.
Example:
Step 1: Calculate the Lumens Per Watt:
\[ LPW = \frac{800}{10} = 80 \text{ lm/W} \]
