Convert between lumens and watts for incandescent, halogen, CFL and LED lightbulbs. Lumens is a unit of luminous flux (brightness), watts is a unit of power.
This free online calculator will help you convert lumens to watts and vice versa. So you can calculate how many lumens the new LED lamps should have based on your previous lights. If you already have some LED lamps on your shortlist, you can convert their lumen value into the output (in watts) of previous lighting.
23 Οκτ 2024 · Learn how to convert lumens to watts, choose the right LED bulbs, and maximize energy efficiency with our detailed guide and conversion charts.
This lumens to watts calculator estimates the power required to achieve your chosen lumen level. Enter the lumens, then either choose the most appropriate light source from the list or enter the lumens per watt of your light source, to get the power in watts result.
Step-by-Step Lumen to Watt Calculation. Identify the luminous flux in lumens (Φ) and the luminous efficacy in lumens per watt (η) for the light source. Apply the formula: P = Φ η. The result is the power consumption in watts (P).
