When you purchase an light bulb, you must understand the difference between watts and lumens as each of these units of measurement measure a different aspect of the light bulb. Watts measure the amount of electricity that the bulb consume, while lumens measure the amount of light that the bulb emits. Many people in the past used the wattage of a light bulb to determine the brightness of that bulb.
However, because moddern light bulb are more efficient, the wattage of the bulb is a less accurate measurement of the brightness of the light bulb. When determining the brightness of a modern light bulb, people should use the lumens measurement to determine the brightness of the light bulb. If you look at a conversion chart for different types of bulb, you can see which bulbs use more watts then others.
Watts and Lumens: How to Choose the Right Light Bulb
Incandescent bulbs use a high number of watts to produce the same amount of lumens as LED bulb. LED bulbs use a low number of watts to produce the same amount of lumens as incandescent bulbs. Using less watt to create the same amount of light means that LED bulbs are more efficient than incandescent bulbs.
Efficiency for light bulbs can be defined as the ability of a light bulb to convert it’s electrical energy into visible light while wasting as little electricity as possible. When you are shopping for a light bulb, you should first determine the level of lumens that you need for you space. This will allow you to purchase a light bulb with the correct brightness for your needs while also minimizing the amount of electricity that it consumes.
People should also consider the efficacy of the light bulbs. The efficacy of a light bulb is the amount of lumens produced per watt of electricity consumed. Light bulbs with high efficacy emit much lumens per watt of electricity used.
These types of bulb will save money on electricity bills due to the low amount of power that they require to create the brightness that they emit. Not all areas of a house require the same type of light. For example, a reading lamp may require a higher level of lumens than a hallway in the same house.
Similarly, the kitchen may require a certain amount of lumens for food preparation. In addition to lumens, people should also consider the color temperature of the lights in the home. For instance, warm lights are best used in bedrooms while cool lights are better for offices.
People should also consider the color rendering index of the bulbs. Color temperature defines the color of the light that the bulb emits. Color temperature can range from 2700K for warm white light to 6500K for cool daylight bulb.
A color rendering index of 100 will allow an object in the light to appear in its true colors while a lower color rendering index will make the colors of the object look dull. Finally, people should also consider the long-term cost of a light bulb. While LED bulbs cost more initially when purchased, they last for many thousand hours longer than incandescent bulbs.
Additionally, LED bulbs use fewer watts of electricity. Therefore, not only will you save money on your electricity bill, but you will also save money on the number of bulb that you have to purchase and replace. Thus, when purchasing a light bulb, you should focus on the lumens specification to determine the brightness of the bulbs and focus on the wattage to determine the efficiency of the bulb.
