Un ikviens, kas iesl\u0113dz gaismu, parasti iesl\u0113dz spuldzi ar 2700 W gaismas punktu. Kelvins<\/a> a - vai v\u0113l slikt\u0101k: energotaup\u012bbas spuldze, kas kaut k\u0101 sp\u012bd da\u017eos spektros... katastrofa!<\/p>\n

T\u0101p\u0113c, druk\u0101jot izm\u0113\u0123in\u0101juma eksempl\u0101ru, vienm\u0113r rodas metamerisms. Ofseta druka<\/a> b\u016btu j\u0101sal\u012bdzina.<\/p>\n
