watts chart below to shop for the right light bulb for your space. For example, if you typically purchase 60W incandescent bulbs, which produce about 700-800 lumens, consider purchasing a lower energy alternative like a 42W halogen bulb, 12W CFL, or even a 10W LED bulb to achieve the same brightness.Ĭlick the equivalent wattage in the lumens vs. Use this chart to determine how many lumens you’ll need from your next light bulb. That’s roughly how bright the sun looks from earth. The IMAX projector’s xenon arc lamp is capable of 600,000 lumens. Household fixtures are commonly found in color temperatures on the Kelvin scale of 2700K (warm incandescent), 3000K (warm white halogen) and 3500K (household fluorescent). LUX and Lumens are related but are critically different. Save for extremely bright, cloudless days, such a portable projector will work superbly at night and quite well during daytime. A typical commercial movie theater projector ranges between 40,000-60,000 lumens. LUX There is no standard that reports the Lux measurement of a projector. That’s why it’s vital you go with at least 500 lumens when choosing a portable projector for external, outdoors use. With energy-efficient lighting like LEDs and CFLs, how many lumens are in a 60W bulb or 100W bulb depends on the lumen output of the bulb, not its energy use.ĭon’t despair! 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. Because they’re projecting on a huge screen, movie theater projectors need to be extra bright. 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. 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. 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. 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. Lumens are the new unit of measurement for light bulbsįor decades, we’ve been buying light bulbs according to wattage. The entry level cost, combined with the high lumen performance, make E-Vision laser projectors perfect for venues with larger screens, as well as venues with. If youre on the move or use a projector across a number of meeting rooms and dont know what level of ambient light youre likely to encounter when you set up your projector, opt for a high brightness projector (4,000 ANSI lumens or more).
