Pravidla pro obaly úsporek, LED i halogenů
Je to už nějaký ten pátek starší, nicméně víte, co lze najít na obalech světelných zdrojů? Respektive, co tam musí být?
Takže první je na úsporkách matematický nesmysl – např. 7W = 35W. Jakoby přepočet zářivkových watů na watty žárovky. Realita je jinde, ale budiž.
Důležitý je i světelný tok v lumenech. الكوتشينة كام ورقة To už je důležitější hodnota… نادي اتلتيكو čím více tím lépe.
Dále životnost zdroje…Berte dost z rezervou desítky tisíc u LED zdrojů, či úsporek…realita je zcela jinde.
Teplota chromatičnosti – dobrý údaj, čím více KELVInů, tím bělejší světlo.
Počet spínacích cyklů pro danou životnost. العب واربح المال Třeba pro zářivku se udávalo 7 krát za den znamená 100% životnost.
Měl by tam být i údaj o obsahu škodlivin (rtuti), zda jde stmívat…
Hitem je energetický štítek, prohlášení o shodě a použitá patice zdroje.
Je to již jasnější? 🙂
