What is the LED Calculator?
The Jands LED Calculator is a quick and easy tool to quantify the electricity cost savings by using efficient LED fixtures. By comparing conventional fixtures against their LED equivalent, a dollar figure can be produced to quantify savings both on a yearly basis and across a period of 10 years. The essential part of the Jands LED Calculator is that it also takes into account the relative purchase price of LED fixtures (which is usually significantly higher) and can make an estimate as to the time required to pay for the initial investment. This is a calculation that is often forgotten in the discussion between LED and Conventional.
How does it work?
The LED Calculator requires the user to first select their location (State/Territory) in order to determine the average electricity price. The user must then input operational data for both Conventional and LED fixtures for the purpose of comparison. You can add multiples of both Conventional and LED fixtures to create a complete real world rig.
The operational data covers the following headings:
- Fixture Type - This specifies the fixture for comparison.
- Quantity - Specify the total quantity of the fixture.
- Hours/Week - Specify the total hours of use per week.
- Operating Level (Conventional Only) - Specify the average operating level of the fixtures e.g. if you only ever use these fixtures at 40%, input that data here.
- Notes - You can add any notes that relate to your fixture.
This data is then calculated against the electricity cost to produce a series of results for both Conventional and LED.
- Annual kWh - Provides a calculation of the annual kilowatt hours of electricity required to power the specified quantity of fixtures for the specified operational time.
- Annual Electricity Costs - Provides a calculation of the total annual electricity cost for the operation of the specified fixtures.
- Annual Lamp Cost - Provides a calculation of the annual cost for the replacement of lamps (bulbs) in the specified fixtures. For Conventional fixtures this is calculated at a 450 hour burn time.
- Total Purchase Price - Provides a calculation of the total initial purchase price for the specified fixtures.
- Total Cost Per Year - Provides a calculation of the total running cost for the fixtures for 1 year. Including lamp cost and electricity.
The LED and Conventional data is then combined to produce a summary of the combined operational savings garnered by using LED over Conventional.
- Total Yearly Operational Savings - Provides a summary of the total operational savings over one year between the specified Conventional and LED fixtures.
- Total Operational Savings Over 10 Years - Provides a summary of the total operational savings over ten years between the specified Conventional and LED fixtures.
- Payback Years (Factoring in initial purchase price) - This provides the total period in years until the operational savings pay for the initial purchase costs of the LED fixtures.
What doesn't get factored in?
There are a number of factors when calculating the savings when using LED fixtures that are extremely hard to quantify. These include labour costs (gel changes, bulb changes), gel purchase costs and air conditioning costs. This calculator focuses only on electricity and lamp costs as these are general factors and can be calculated without specific situational requirements.
