Explanations on energy consumption:

• HPS/MH lamps consume 8% more energy than nominal power.
• LED lamps consume the same energy as nominal power.
• CFL lamps consume 40% less energy, as manufacturers specify internal rather than external power.

This calculator was designed for users who want to accurately estimate the energy consumption and costs of using different types of lamps for indoor plant growing.

The calculator allows you to choose a lamp type (HPS/MH, CFL, LED), enter nominal power, number of lamps, hours of operation per day, and number of usage days.

After entering the current rate per kW/h (in USD or EUR), the calculator precisely calculates the total energy consumption and cost.

By using this tool, you can easily understand how different types of lamps impact energy consumption and identify potential savings by choosing more efficient lighting. This is an invaluable tool for anyone looking to optimize indoor plant growing costs and manage electricity bills effectively.
