Aquarium Electricity Calculator
3
Use this calculator to help determine how much money you currently spend to run and maintain your existing aquarium lights and compare that with what it would cost to convert your lights to LED. LED light fixtures can have a relatively high up front cost, but they also generate cost savings through reduced consumtion of electricity and eliminating the need to replace bulbs annually. Enter the values in the input section and the spreadsheet will provide your calculations in the Output section. Please do not type anything in the output section.
