What? 2700K is the most common “warm” color sold. The lower the temperature Kelvin the warmer the shade of white. the K stands for Kelvin, and it is a measure of color temperature. Next lets answer “how bright is 3000K?” “How bright is 2700K?”, “How bright is 3500K?”, ‘How bright is 4000K?”, “How bright is 5000K?” K has absolutely nothing to do with brightness. So, what is the answer to the question “how do you convert lumens to watts?” It depends. Most LED light fixtures are between 130-150 lumbens per watt. Fixtures are typically more efficient than bulbs. Recently some manufacturers have come out with 6 Watt, 800 lumen bulbs. First, an A19 LED bulb that is a 60W equivalent is about 9W and is 800 lumens. The reality is that the brightness is correlated to wattage, but as we get more efficient LEDs the number of lumens per watt delivered by an LED diode is getting higher.
We have perpetuated this incorrect association by putting 100 Watt equivalent on common light bulb packaging (A19 LEDs, BR30 LEDs, etc). A 100 Watt incandescent bulb was about 1600 lumens.
When we used incandescent light bulbs we incorrectly described brightness as wattage. Changing all three elements of the bulb will substantially alter the aura in your space.The first question - How do you convert lumens to watts? The answer is that you don’t. When you dim a light bulb, it lowers the wattage, decreases the Kelvin temperature (to a red/orange hue), and reduces the lumens on the brightness scale. A dimmer will let you change the ambiance of a room immediately. Sometimes, you want your living room to exude a chic, cozy vibe, but other times, you need to provide a well-lit space for dinner parties and other big events.

Although the whiter lights will appear “brighter” than those of a lower Kelvin reading, the amount of lumens on the brightness scale does not change, and true brightness is not affected. Generally, the higher the Degrees Kelvin, the whiter the color temperature of the bulb. In addition to determining lumens on a brightness scale, you also want to figure out the color of your light bulb. A 100 square foot bathroom, however, will need 7,000 lumens total, distributed between all the light bulbs.
A 100 square foot bedroom, for example, will need about 1,000 lumens total, dispersed between all the light bulbs in the space.
In order to decide how many lumens you need to light a room, you should consider the general rule that designers and architects use:īedrooms and living rooms need about 10-20 lumens per square foot, while kitchens and bathrooms need around 70-80 lumens per square foot. When you’re trying to figure out the appropriate lumens on the brightness scale for your bulbs, that’s a whole other animal. You may already know about the different types of light that you need to layer to properly light a room, but we’re not here to talk about ambient, accent, and task lighting!
