As lumens are now the accurate measurement for light bulb brightness, this lumens chart compares bulb types with their watts vs lumens for quick selection.
We all know how much light a 60-watt bulb will produce. But the brightness of new CFL and LED lightbulbs are measured in lumens, not watts, so here’s a handy chart to help you do the conversion. Lightbulb Watt-to-Lumen conversion chart
So, if you previously bought incandescent bulbs measured in watts, here's a handy guide showing how many lumens you might need and the wattage conversion. Note that these conversions use a set average figure for lumens per watt (lm/W), based upon data from the Energy Saving Trust and Energy Star.
To make sure you get the same brightness from your energy efficient bulbs, use this chart to compare the wattages of different technologies.*. Using the chart we can see that if you want to replace a 40W incandescent light bulb with a compact fluorescent (CFL), you will likely need a 7W CFL.
Lumens measure the amount of light created by a bulb, whereas watts measure the energy used by the bulb to produce lumens. Traditionally, we’ve referred to light bulbs by their watts because most people used incandescent light bulbs and knew difference between a 60 and 100 watt bulb.
1 ημέρα πριν · 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.
lm/W stands for lumens per watt and 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.
