Switching to LED lighting saves significant energy thanks to far higher lumens per watt. This tool compares your current (old) and new (LED) lighting's wattage, count and daily usage hours to calculate yearly kWh, cost and kg CO₂ savings, plus a payback period based on an investment amount you optionally enter.
