LED Calculators: Energy Consumption, Savings, and Return on Investment
A responsible consumer strives to reduce energy consumption whenever possible. A great way to do this is to replace in-efficient lighting systems with ones that are more efficient. Switching to LED light sources is a great start. Even though some initial investment is needed, the energy and maintenance savings pay off that investment in a relatively short time.
The following calculators provide some very useful estimates. The first calculator simply estimates the cost of any lighting system (regardless of lamp type). The second calculator allows you to compare the costs of an older system with a newer LED system. The third calculator gives you an estimate on the payback time when you invest in an LED system.
