Look for these labels, and try to judge bulbs by lumens instead of watts. The FTC,В in particular, has worked to create new labels with a вЂњBrightnessвЂќ heading that provides the lumens for customers. Which is brighter today, a 40-watt fluorescent or a 60-watt incandescent? ThereвЂ™s no reliable way to tell.ДЄs a result, manufacturers are now focusing more on lumens as a way to tell customers how bright a bulb is. LEDs, fluorescents, and more-efficient incandescents all have varying levels of wattage, and that wattage is no longer tied to brightness. A 60-watt bulb would always produce a certain amount of light, a 100-watt bulb would be reliably brighter, and so on and so forth. In the old days, you had certain categories of incandescent lightbulbs that were measured in watts, and those watts could also be used to tell the brightness. Why is this? Because the market is now more varied, and products have grown far more efficient. Lumens are quickly becoming a more useful measurement for products like lightbulbs. How does this help you? LetвЂ™s go by device This wear and tear affects projector bulbs in particular, and weвЂ™ll talk a little more about that below. However, bulbs and diodes donвЂ™t stay the same forever: Some - particularlyВ the brightest bulbs - will decrease in lumens over time as they wear out, no matter how many watts of energy theyвЂ™re using. In other words, a certain amount of watts will produce a certain amount of lumens in brightness for a given bulb. Technology aside, lumens have a close-to-linear relationship with watts. but lumens are particularly useful for measuring light in common products like bulbs. There are many other ways to measure brightness - lux, nits, etc. In science-speak, the luminous flux produced by one candela across a solid angle of one steradian equals one lumen. A bulb with a hood that only shines light in a singleВ direction will technically produce far fewer lumens than that same bulb shining light in every direction at once. Lumens also take into account how the light is projected. They tell you the visible light intensity that is produced by a bulb or other lighting device. This is quickly changing in todayвЂ™s market, however. However, for a long time dimmer bulbs required a lower number of watts than brighter bulbs, so we got used to using watts as a sort of shortcut to describe brightness. Interestingly, watts do not measure brightness, nor does the number of watts say anything about brightness at all.

So, a 100-watt bulb that you turn on for 10 hours uses around 100 watts constantly, or 1,000 вЂњwatt hours.вЂќ This is also known as a kilowatt, which is a common measurement for the expenditure of energy in your house. One watt equals one joule per second ( you can go down that physics rabbit hole if you want to). Watts are all about real power, which means they measure the rate at which energy is consumed. Watts are a measurement of energy, specifically the energy needed to power electronic devices like lightbulbs. Olegdudko/123RFWatts and lumens - they both describe lightbulbs, but do you know what they actually mean? Did you know that wattage is no longer a reliable way to tell how bright a bulb is? Do you know what makes lumens a worthwhile successor? LetвЂ™s talk about the two most famous light specs, and how they affect your search for the best bulbsВ on the market.
