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. NettetLuminous efficacy is a measure of how well a light source produces visible light. It is the ratio of luminous flux to power, measured in lumens per watt in the International System of Units (SI). Depending on context, the power can be either the radiant flux of the source's output, or it can be the total power (electric power, chemical energy, or others) … henry belin du pont
