How Much Could Your Lighting Upgrade Save?

Match your existing lamps with a compatible GY replacement and estimate the annual impact before you buy.

1

Tell us what you are replacing

We use this to estimate the closest output range.

2

Describe your project

Choose a common value or enter your own.

Tariff presets are rounded starting points. For the most accurate estimate, enter the rate shown on your electricity bill.

Method and assumptions

Estimates depend on operating hours, electricity tariffs and the actual lamps being replaced.

Annual saving = (old watts − recommended watts) ÷ 1,000 × hours per day × operating days. Project saving multiplies this by the number of bulbs and your electricity price.

Country presets are indicative household rates and can differ from your contract. Product matching uses typical wattage equivalence; always confirm lumen output and fixture compatibility. Results exclude product purchase, installation, maintenance, taxes and future tariff changes, and are estimates rather than guaranteed savings.
