Watts measure the amount of energy required to light products, whereas lumens measure the amount of light produced. The more lumens in a light bulb, the brighter the light. We all know how much light a 60 – watt bulb will produce. But the brightness of new CFL and LED lightbulbs are measured in lumens, not watts, so here"s a chart to help you do the conversion. Lumens and watts are different, which can make it harder to figure out what type of bulb to buy. And while a standard 60 – watt incandescent bulb has 870 lumens, a halogen bulb of the same wattage has 960 lumens and lasts three times as long! In the past, we bought lightbulbs based on how much energy, or watts, they use.
For decades, we have been buying light bulbs based on how much energy they consume ( Watts ) — no matter how much light they give us ( Lumens ). As a consumer, can you really understand what it means to purchase a 60 – watt CFL or incandescent bulb against a 12 lumens LED? You can roughly know about how many watts in a bulb can produced the required brightness only by plugging it in the socket. The light bulb makers actually pushed – lobbied – for the passage of the new Energy Act because while most of us were making. But one of the newest LED bulbs, the Cree Standard 60W Replacement LED, puts out 800 lumens with only 9 watts of power. Buy 60 – watt Incandescent bulbs now! With traditional incandescent light bulbs it was simple to make sure you were getting the right light bulb.
With newer types of bulbs, it takes far fewer watts to create just as much light, so wattage ratings are no longer very useful. Each type of bulb is different, and the whole idea. Measuring and labelling light output instead of energy use makes it easier for you to find the right energy efficient bulb for your space. For example, if you typically purchase 60W incandescent.
Again, comparing the lumen output of your old bulb (if you still have an original package) to the lumen output of the CFL you plan to purchase should help you to avoid purchasing an inadequate. The info is usually on the boxes though. Anyone at home have some spare light bulbs in their boxes that can check the lumen ratings of 40 and 60 watt bulbs ? This is in reference to your "normal" light bulb. Also, if anyone can check on wattage ratings. Common terms are "soft white 60," "warm light 60," and " 60 watt replacement. Sometimes a diagram will show two images or an equal sign, much like the packaging image to the right. To save energy, find the bulbs with the lumens you need, and then choose the one with the lowest wattage. If you used to buy this in incandescent, Look for this much light in lumens, LED (most efficient), CFL (more efficient), Halogen (more efficient incandescent).
The relative efficiency of different lightbulbs can be gauged by comparing how many lumens they produce for every watt of electrical power. The WATTS is a measure of the amount of energy used by bulbs and the LUMENS is the measure of brightness provided by a light bulb (the higher the lumens the brighter the bulb ). Those 60 watt bulbs you used to get now have a new label on them, revealing how many “ lumens ” a light may provide. The new light bulbs use less power to give off the same amount of light. Therefore, consumers will no longer be buying bulbs simply.
In the near term, manufacturers are including claims like "replaces 60W bulb " or "13 W = 60 W " for a 13-watt CFL that gives off as much light as the old. LED equivalent is on the high end of the scale. The figures used above are for comparison only, and are not exact. Residential energy costs among the various states range from 28. Whats the difference between Watts and Lumens. Manufacturers are still working on fitting all the chips and circuitry needed to produce enough lumens into a standard-size bulb . The quality of light is warm and natural, much like sunlight. For years, people have chosen light bulbs by the watt, learning over time about how bright a typical 40-watt or 60 – watt bulb is. But wattage tells you only how much energy a bulb uses — not how bright it is.
With newer light bulbs designed to use less energy, wattage is no longer a reliable way to gauge a. Many people are finding that choosing the right light bulb has a steep learning curve. An incandescent 60 – watt bulb, for example, gives off 800 lumens of light. But with so many types of bulbs with different price points and life spans now on the market, many consumers are confused.
