INVERTER POTENZA 300 Watt Effettivi Convertitore Da 12v A 220v
The old technology of tungsten incandescent bulbs only had an efficacy of about 15 lumens/watt. Depending on the bulb and the manufacturer, LED technology typically produces 75-110 lumens/watt. So, LEDs are generally about 7 times more efficient at producing light than incandescent bulbs. Use a 7:1 ratio as a rough guide when selecting an LED.
