550 lumens in watts

In recent years choosing light bulbs has become far more confusing — you knew roughly what you were getting with a 40, 60 or wattage filament bulb. Nowadays, energy saving bulbs produce far more light, less heat, whilst consuming less energy Watts. Defining the brightness, or light output of bulbs is changing from wattage equivalents to lumens. Lumens is an accurate way of measuring the light output of bulbs — brightness is what we perceive, luminance is what we measure. However, this can be a little confusing! Most of us have a preconception of how bright a watt incandescent bulb is even though this can vary tremendously between soft white and clear glass bulbs. On average, an incandescent bulb produces around 14 lumens per watt, compared to 63 lumens for energy saving compact fluorescents CFL and 74 for LED bulbs. Some of the most energy to light efficient LED bulbs are now reaching over lumens in Energy Star tests. A 40 watt incandescent filament bulb produces roughly lumens. An equivalent compact fluorescents CFL bulb in light output lumens should consume only around 7 watts and LEDs approximately 6 watts. The colour of light can also affect how bright a light appears, even if the lumens are the same.

Lumens is a unit of luminous flux brightnesswatts is a unit of power. Bulb efficiency may vary.

But as energy-efficient, low-watt light bulbs like CFLs and LEDs have become readily available, watts have become an unreliable metric for selecting bulbs. Instead of focusing on wattage, which measures power or energy use, manufacturers are indicating the brightness of their energy-efficient bulbs according to lumens, which measure light output. So while we may be accustomed to shopping for bulbs according to wattage, lumens are actually a more accurate measurement of how bright your light will be. How many lumens are in a watt? Because lumens measure brightness and watts measure energy output, there is no simple method for converting wattage to lumens. With energy-efficient lighting like LEDs and CFLs, how many lumens are in a 60W bulb or W bulb depends on the lumen output of the bulb, not its energy use. Measuring and labelling light output instead of energy use actually makes it easier for you to find the right energy-efficient bulb for your space.

Philips Hue offers different ranges of brightness in its smart bulbs so that you can get the perfect amount of light for any room in your home. Use this guide to learn more about lumens and smart bulbs, how to convert from lumens to watts, and how to choose the right brightness. Lumens measure how much light the human eye can see coming from light source — the brightness of a light bulb, for example. The higher the lumen rating, the brighter the light appears. This measurement is different from watts, which indicate the input power of a light bulb rather than its light output. You may see the numbers , , , , , , , and when shopping for Philips Hue bulbs. Some will reference K, which is a bright white light. Others will reference K or K, both of which are warmer and more golden.

You can use our lumens to watts calculator to calculate the efficiency of different bulbs and low wattage LEDs based on their brightness to power ratio, known as luminous efficacy , where the brightness of the light is in lumens and its power, in wattage. You can then compare your LED bulb wattage with other light bulbs to observe how much electricity you'll save. Omni's electricity cost calculator will make the task even easier. And to further reduce your electricity bill, you may try our outstanding appliance wattage calculator. Furthermore, we will tell you how to calculate lumens to watts using a formula and show you a comparison chart of LED wattage consumption against other bulbs. We can use this lumens to watts calculator to find the required LED bulb wattage , i. You can also use it to find the luminous flux , i. Finally, we can find the luminous efficacy , i. For reference, the sun at noon measures about 1.

In case of LED lamps and luminaires, the specified wattage plays only a subordinate role. In recent years choosing light bulbs has become far more confusing — you knew roughly what you were getting with a 40, 60 or wattage filament bulb. For Professionals. You will find the 60 watt bulb in the 3rd row of the 2nd column. The tools in this website are provided "as is" without any warranty of any kind. You can simply replace your existing lamps or upgrade to the latest versions if you're feeling green. The process of identifying which fluorescent tube you require can be a bit of a minefield, but if you follow our step-by-step guide, yo When we pay our electric bill, we pay for the number of watts we use. Home solar panels and battery energy storage explained. We knew that a 75W lightbulb produced more light than a 40W bulb. Shop Now. From abacus to iPhones, learn how calculators developed over time. June 2, Posted by Sonja Dean. To find LED lamps with the correct brightness, you should use the lumen value of the old lighting as a starting point.

How bright is lumens? Just what is that level of light good for? We give you real life applications and comparisons to help you understand what levels of brightness certain quantities of lumens will deliver.

Continue Shopping. Converting Lumens to Watts How many lumens are in a watt? Description Can be switched on and off frequently without affecting the lifetime of the LEDs Equivalent to watt incandescent while only consuming 7 Watts of energy Rated for damp locations where protected from direct contact with water Dimming feature allows you to control the lighting level as needed Presenting a bright Kelvin daylight white color, this PLTL LED BR20 bulb is excellent for use in task lighting applications. Lumens is an accurate way of measuring the light output of bulbs — brightness is what we perceive, luminance is what we measure. The values are average values of the respective lighting technology and vary by manufacturer. February 1, Posted by Sonja Dean. Using the ratio, simply divide 60 watts by 7 to get roughly 9 watts. We offer guarantees on all our products and if things aren't quite right - you can return your items to us quibble free within 14 days of receipt. October 12, Posted by Sonja Dean. For the comparability of LED lamps the actual brightness is indicated in lumens. Please share.
