This will help moderate the light intensity of your LED bulbs both during the day, and at night. To do these three layers well, you’ll need to understand the terms used to describe light bulbs: Kelvin: A scale of measurement for the “color” a light produces. Hence, determining the Watt for each bulb isn’t the problem. It is described as the brightness of a light bulb measured from a distance of one foot. The foot-candle requirement varies between rooms depending on the purpose and type of room being considered. To get the square footage, all you need to do is multiply the length of the room in feet by the width of the room in feet. Accent (for highlighting a piece of art or focal point). The reason why the lumen is so important is; Watts simply tell you how much power is consumed by a bulb. With Dimmers, the same light fixture can be high intensity for tasks in the day, and low intensity for nights. eval(ez_write_tag([[300,250],'lampslab_com-box-4','ezslot_11',111,'0','0'])); As we stated earlier, the wattage is not a measure of brightness, but a measure of the amount of electricity a bulb consumes in order to reach its claimed brightness. However, people often make the mistake of assigning the same wattage LED bulbs to these rooms. eval(ez_write_tag([[580,400],'lampslab_com-large-mobile-banner-2','ezslot_9',117,'0','0'])); As a precaution, when purchasing a light bulb, it is best if you also get a dimmer.
