Lumens to Watts Calculator For All Types of Bulbs
500W halogen bulbs emit approximately 9,000 to 10,000 lumens. How many watts is 1600 lumens? It depends on bulb type. Approximate values:
The lumens to watts calculator allows you to convert luminous flux (lumens) to electric power (watts), considering the luminous efficacy of the light source. Ideal for comparing LED, fluorescent, incandescent, halogen, and CFL. Useful for energy saving and lighting projects.
Let's say you need 900 lumens of light for a room: Power needed: 900 / 90 = 10 watts Compare this to an incandescent bulb with 15 lm/W: Power needed: 900 / 15 = 60 watts This clearly shows the energy efficiency advantage of LED over traditional bulbs. Here's a helpful reference table for quick conversions:
100 lumens is the measure of brightness, not power consumption. If you're using LED bulbs, 100 lumens typically requires around 1-2 watts. For incandescent bulbs, it would take about 15 watts to produce the same 100 lumens of light.
Watts = Lumens / Luminous Efficacy (lm/W) For example, if an LED bulb provides 900 lumens and has a luminous efficacy of 100 lumens per watt (lm/W), it uses only 9 watts of power. By using this formula, you can easily determine the most energy-efficient option for your lighting needs.
