Zrazu sa za\u010dalo objavova\u0165 osvetlenie v uliciach a v dom\u00e1cnostiach a \u013eudia u\u017e neboli z\u00e1visl\u00ed na petrolejov\u00fdch lamp\u00e1ch a voskov\u00fdch svie\u010dkach. M\u00f4\u017ee sa v\u00e1m to zda\u0165 ako hl\u00fapos\u0165, ale sk\u00faste si niekedy by\u0165 nie jeden de\u0148, ale cel\u00fd t\u00fd\u017ede\u0148 bez elektriny a svi\u0165te doma svie\u010dkami. Spo\u010diatku sa v\u00e1m upokoj\u00ed myse\u013e a budete ma\u0165 viac \u010dasu na seba a budete sa treba aj \u010dastej\u0161ie milova\u0165 alebo hra\u0165 spolo\u010densk\u00e9 hry, ale po t\u00fd\u017edni sa v\u00e1m to u\u017e za\u010dne zajeda\u0165 a svit svie\u010dok \u010di petrolejky v\u00e1m bude pripada\u0165 nedostato\u010dn\u00fd. Edison n\u00e1m teda priniesol volfr\u00e1mov\u00fa \u017eiarovku. S tou sme svietili mnoho rokov, v podstate takmer cel\u00e9 dvadsiate storo\u010die a e\u0161te p\u00e1r rokov po tom, k\u00fdm sa neza\u010dalo masovo vyr\u00e1ba\u0165 LED osvetlenie. V roku 1993 u\u017e bola vyn\u00e1jden\u00e1 ch\u00fdbaj\u00faca modr\u00e1 di\u00f3da a bolo teda mo\u017en\u00e9 zostavi\u0165 spolu s \u010dervenou a zelenou di\u00f3dou biele svetlo. Akon\u00e1hle bolo biele LED svetlo k dispoz\u00edcii, volfr\u00e1mov\u00fdm \u017eiarovk\u00e1m postupne odzvonilo. Nev\u00fdhodou volfr\u00e1mov\u00fdch \u017eiaroviek je ich ne\u00fasporn\u00e1, teda ve\u013emi drah\u00e1 prev\u00e1dzka. Ak napr\u00edklad osad\u00edte klasick\u00fd stropn\u00fd luster \u0161iestimi \u017eiarovkami s pr\u00edkonom 100 W, m\u00e1te razom odber 600 W a to sa potom v\u00fdrazne prejav\u00ed na spotrebe elektriny v dom\u00e1cnosti. Ke\u010f ale namontujete do tohto lustra \u0161es\u0165 LED \u017eiaroviek E27 s pr\u00edkonom iba 7 W a rovnakom svetelnom toku, ak\u00fd maj\u00fa tie volfr\u00e1mov\u00e9 \u017eiarovky, spotreba elektriny klesne na 42 W a to u\u017e je pozna\u0165. Obrovskou v\u00fdhodou modern\u00fdch LED \u017eiaroviek je ich kompatibilita s osvet\u013eovac\u00edmi telesami star\u0161ieho d\u00e1tumu v\u00fdroby. Tak\u017ee napr\u00edklad v tom \u0161es\u0165ramennom lustre s obj\u00edmkami E27 m\u00f4\u017eete ma\u0165 modern\u00e9 \u017eiarovky, aj ke\u010f samotn\u00fd luster poch\u00e1dza z roku 1989. My si tak\u00fd luster zaobstarali na novoman\u017eelsk\u00fa p\u00f4\u017ei\u010dku, bol kr\u00e1sny a keby ho m\u00f4j syn nedemontoval, mal by som ho v byte dodnes. A pr\u00e1ve Edisonov z\u00e1vit na \u017eiarovk\u00e1ch E27 je pozostatok a spomienka na vyn\u00e1lezcu Thomasa Alva Edisona, ktor\u00e9ho genialita umo\u017enila \u013eudstvu \u00eds\u0165 cestou technick\u00e9ho pokroku.
