As LED is the predominant choice for light bulbs since they are more energy-efficient than incandescent and CFL (compact fluorescent) options, this LED lumenschart makes comparisons from the brightness in lumens to LED and other common types of light bulbs. Simply find the type of your bulb choice on the left, and use its wattage to find the corres...
When shopping for light bulbs, you may have come across the terms “watt” and “lumen.” But what do these terms mean? A watt (W) is a unit of power that measures how much energy a bulb uses. A lumen (lm), on the other hand, is a unit of measurement that describes the actual brightnessof light coming from a bulb. So in other words, the watt tells you ...
So although wattage is not the most accurate of measurements for brightness anymore, it’s been used for so long as the main way to compare bulbs that the old incandescent watts to lumens comparison is still helpful to visualize the brightness of each lumen level, to aid your comparisons. Here is a breakdown of traditional watt light bulbs and the a...
However, lumens are only part of the story, the type of bulb you choose will also affect the look and feel of the light. The brightness of a light bulb also depends on its color temperatureand beam spread. A colder light (with a higher color temperature) will appear brighter than a warmer light, even if they have the same number of lumens. Similarl...
Oct 31, 2023 · Here are some basic equations for each major bulb type: LED: Lumens = Watts x 80. CFL: Lumens = Watts x 70. Halogen: Lumens = Watts x 20. Incandescent: Lumens = Watts x 15. Metal Halide: Lumens = Watts x 60. Note that these equations reflect the average lumens produced per watt for each bulb type.
