Jedovate svetlo LED?

[Zuffa Jan]

Mna napada, ze LED svetlo nie ucinne
nici bakterie a tie su potom povodcom
spominanych problemov.
V ordinaciach sa bezne pouziva UV svetlo
na dezinfekciu (v case ked tam nikto nie je :) )

Trochu jsem to nepochopil. To má jako králíkům vadit že ledky nemají UV záření? Všude se to uvádí jako výhoda a pokud se to někomu nelíbí, může si k tomu přidat pár UV ledek. Pán by měl s pokusama pokračovat a pár králíkům svítit žárovkama. U ledek se uváděl jiný problém, že mají výraznou spektrální čáru na modré. To byl problém luminoforů, které dosahují CRI okolo 80. Nové typy luminoforů s CRI okolo 95 už mají tohle maximum dost dobže potlačené a na modrozelené taky není ta díra ve spektru, co bývala. I barevně se tyhle ledky v barevné teplotě 3000K dost podobají žárovce.
