Nettet1 ft LED strip = 450 lumens = 1-ft T8 Fluorescent. 4-ft T8 fluorescent lamps emit approximately 3000 lumens. However, because it emits light in all directions, much of it is "lost" in the fixture. When replacing T8 fluorescent lamps with an LED solution such as LED strip lights, we recommend budgeting 450 lumens per foot as a direct replacement. Nettet29. mai 2015 · 1 Answer. Lumens do add up. So if you have one n lumen flashlight and another m lumen flashlight the total luminous flux will be n+m. However interestingly our eyes (and ears) don't operate on a linear scale. 2x the lumens will not be perceived as 2 times the brightness because our eyes and ears work on a logarithmic scale. NettetLysutbytte (lm/W) Dette er hvor mye lys du får sammenholdt med energien som brukes. Glødelamper hadde et lysutbytte på litt under 15 lumen/watt. Halogenpærer ligger 30 til 40 prosent høyere. Utviklingen av LED nærmer seg nå 100 lumen/watt, slik at dette er langt mer effektivt for belysning enn tradisjonelle lyskilder. motel\\u0027s wh
