Convert Lumens to Watts
Watts = Lumens ÷ Lumens per Watt. Lumens per Watt (lm/W) depends on bulb type. For example, 800 lumens to watts for an LED (100 lm/W) = 8
A 1000W metal halide bulb typically produces around 90,000 to 110,000 lumens, depending on brand and age. How many lumens is a 500 watt halogen bulb? 500W halogen bulbs emit approximately 9,000 to 10,000 lumens. How many watts is 1600 lumens? It depends on bulb type. Approximate values: What's the most efficient lighting option?
The basic lumens to watts formula is: Watts = Lumens ÷ Lumens per Watt Lumens per Watt (lm/W) depends on bulb type. For example, 800 lumens to watts for an LED (100 lm/W) = 8 watts. Here's a quick guide using LED bulbs at 100 lm/W: Also see: Lighting Converters Found this tool helpful? Share Mainconverter with your friends!
To convert 500 watts to lumens: Find the type of bulb to determine its luminous efficacy. Then multiply the wattage of the bulb with its luminous efficacy to obtain lumens. For example, if our 500 watts bulb has a luminous efficacy of 40 lm/W: The amount of light it can produce will be 500 × 40 = 20,000 lumens.
For an LED bulb with an efficiency of 90 lumens per watt: For a CFL bulb with an efficiency of 60 lumens per watt, the wattage required would be: Different bulb types have different efficiencies. Here are the typical efficiencies for common lighting technologies: When selecting the right bulb, consider the following factors:
