Vyzeral fantasticky a k existuj\u00facemu n\u00e1bytku sa \u00fa\u017easne hodil. Zdobil strop ob\u00fdvacej izby a v rovnakej miestnosti sa k tomu nach\u00e1dzala aj stojaca lampa s textiln\u00fdm tienidlom a prekr\u00e1sne biele tapety s ve\u013emi jemn\u00fdm vzorom. Miestnos\u0165 bola zariaden\u00e1 ve\u013emi vkusne a ten luster v nej navy\u0161e poskytoval naozaj mnoho svetla, preto\u017ee sa v ka\u017edej jednotlivej obj\u00edmke nach\u00e1dzala \u017eiarovka s volfr\u00e1mov\u00fdm vl\u00e1knom s pomerne vysok\u00fdm pr\u00edkonom. U\u017e si presne nepam\u00e4t\u00e1m, o ak\u00e9 \u017eiarovky i\u0161lo, ale domnievam sa, \u017ee 60 alebo 100 W. Ak tam boli \u017eiarovky 100 W, dohromady teda tento luster vy\u017eadoval pr\u00edkon 600 W, \u010do na vtedaj\u0161iu dobu konca osemdesiatych rokov zodpovedalo pribli\u017ene prev\u00e1dzke klasickej \u017eehli\u010dky. Len\u017ee v tom \u010dase bola cena elektrickej energie niekde \u00faplne inde. Nebol teda probl\u00e9m ka\u017ed\u00fd de\u0148 svieti\u0165 t\u00fdmto lustrom napr\u00edklad po dobu \u0161iestich hod\u00edn, \u010do denne spotrebovalo 3,6 kWh elektrickej energie. V s\u00fa\u010dasnej dobe je v\u0161ak tak\u00fd sveteln\u00fd zdroj ne\u00fasporn\u00fd a jedn\u00e1 sa o zbyto\u010dn\u00e9 plytvanie peniazmi, preto\u017ee je mo\u017en\u00e9 nahradi\u0165 v takom lustre existuj\u00face \u017eiarovky LED \u017eiarovkou 12v 5W so z\u00e1vitom E27, ktor\u00e1 pri zhruba zhodnom svetelnom toku vy\u017eaduje iba 5W.\u013dahko si potom spo\u010d\u00edtate, \u017ee za t\u00fdch \u0161es\u0165 hod\u00edn denn\u00e9ho svietenia spotrebuje tak\u00fd luster iba 0,18 kWh. Najv\u00e4\u010d\u0161ia \u00faspora elektriny sa prejav\u00ed v dlhodobom horizonte, teda napr\u00edklad za jeden rok ka\u017edodenn\u00e9ho svietenia po\u010das \u0161iestich hod\u00edn spotrebuje p\u00f4vodn\u00fd zdroj celkom 1 314 kWh elektriny, zatia\u013e \u010do LED \u017eiarovky iba necel\u00fdch 66 kWh elektriny. Tu je vidite\u013en\u00fd obrovsk\u00fd rozdiel, ktor\u00fd sa u\u017e v pe\u0148a\u017eenke prejav\u00ed ove\u013ea viac.
