![]() The lumen-to-watt ratio varies depending on the type of light sources, such as LED, fluorescent, halogen, or incandescent bulbs. Wattage measures the electricity or energy a light bulb consumes to produce its lumen output. Below we will use lumens as a measurement to ensure we have enough light for a space. Light sources such as LEDs, Fluorescents, Halogens, and Incandescents have different lumen-per-watt ratios. Wattsīulb brightness is not measured it is the amount of electricity (or energy) a bulb consumes to reach its claimed brightness. LED lights have a higher Color Rendering Index (CRI), meaning they more accurately reveal the subject's colors being lighted but do not provide more light. This means 600 LED lumens provide the same light as 600 incandescent lumens. A standard 100-watt incandescent light bulb produces around 1,500-1,700 lumens. Lumen output measures the brightness or light output emitted by a light source. Feel free to contact us with any questions.“How many lumens do I need to light a room? ” is a frequent question. Each of our fixtures is handmade just for you, and we welcome any questions about which design will be right for your space. Choose from different fixture sizes, customize with different colors, or pick several fixtures to complement one another. We offer a variety of chandeliers, flush mounts, pendants and sconces for traditional, modern and mid-century styles to illuminate your space. ![]() Choose a fixture from Dutton Brown, and we'll help you make it perfect for your space. If this isn’t enough, consider a fixture with more sockets or consider installing additional track lighting, lamps, or sconces. For example, a fixture with 4 sockets installed with 800 lumen bulbs will produce 3200 lumens. Pay attention to the number of sockets on the fixture you purchase and note also the lumen count on the bulbs you purchase. In general, using more sources of light with bulbs that are less bright is better than using fewer sources of light with bright bulbs, because bright bulbs may cause eye strain. The first way is to add more sources of light (or more bulbs), and the second way is to use brighter bulbs. There are two ways to add light to a space. Choose a fixture and bulbs that achieve the calculated amount of lumens For example, for a bathroom that is 64 square feet with a foot-candles range of 70-80, you’ll need from 70圆4 to 80圆4 lumens, or 4480 – 5120 lumens. To estimate the number of lumens your space will need, just multiply the square footage of your room by the number of foot-candles required for the space. Lumens are a measure of brightness, or the amount of light emitted per second by a light source. Establish how many lumens will be needed to light your space You can see, for example, that a kitchen or bathroom will require more light than a hallway or bedroom.ģ. The below table summarizes approximate light intensity ranges using foot-candles for several spaces. A foot-candle measures light intensity and is defined as the number of lumens cast on a one square foot area. Whether you plan to light the room for task work or for ambience, you can get a good idea of how bright a space should be by using a unit called a foot-candle. 2. Determine the "foot-candle" factor by room type.ĭifferent rooms need different amounts of light depending on how the rooms are used. Say the bathroom you are installing a light fixture in is 8 feet long by 8 feet wide (8 x 8 = 64). Multiply the length by the width of the room to determine the square footage. The size of your room affects how much light your space requires. Calculate the square footage of your room Or for a quick summary of three important points to consider, check out our video from our series "Get Lit" below.ġ. ![]() Follow our guide below to calculate how much light your space needs so the light fixtures you choose are sure to be the right ones. ![]() ![]() One of the most common questions about lighting regards whether a light fixture will be bright enough for a space. ![]()
