When buying lightbulbs, you'll see commonly see several measurements listed on the packaging. Perhaps the most recognisable one, which has existed for decades, is the wattage. However, times are achanging, and innovation has led us into updating how we rate and reference our bulbs. Enter the lumen.
The Watt is a unit of power. The Lumen is a measurement of light output. For our lightbulbs, the lumen defines the perceived brightness of a specific bulb (such as an LED fixture). In the past, we commonly bought conventional bulbs on the basis of wattage. We knew that a 75W lightbulb produced more light than a 40W bulb. Over time, the technology i...
lm/W stands for lumens per wattand is a unit measuring luminous efficacy and energy efficiency - how much visible light is produced for a given amount of electricity. As an example, a 60W incandescent light bulb may produce around 900 lumens, giving it a luminous effacy of 900/60 = 15 lm/W.
When swapping out your old incandescent or halogen bulbs for more energy-efficient CFL or LED bulbs, you may wish to have a comparison to ensure you get the same level of brightness (lumens) from your bulb. To assist you, we have provided a handy conversion table below. Note that efficacy can vary, often wildly, between manufacturers. So, do check ...

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. Lumen Watt Calculator.
Deciphering the Chart. A conversion chart for lumens to watts provides lumen values alongside their respective wattage equivalents. This helpful table assists individuals in picking the right bulb type between LED, CFL, and incandescent by giving them a direct read on what wattage should be used depending on the desired brightness (lumens).
May 3, 2024 · 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.
Oct 31, 2023 · Our lumens to watts conversion chart below simplifies the correlation between these two light measurements, ranging from 100 to 10,000 lumens. Armed with this knowledge, as business owners and homeowners, you'll be able to compare and contrast the main types of lighting in terms of watts and lumens.
