Effects of Blocklight Energy on People
Blocklight energy os emitted by blocklight lomps isolso emitted by sun ond sky lights ond is lherefore onoturol componeni of our environment. Blocklighlenergy from filtered noturol lighl or blocklighl lomps,couses the eye medio to fluoresce producing senso-tions thot hove been described os unusuol or uncom-fortoble. The fluorescence of the eye medio istemporory, existing for lhe time of exposure ondproducing no known ofter effects.
Fixh.rres for Blocklight Blue lomps
Blocklight lomps ore equivolenl to other fluorescenllomps in eleclricol ond physicol choroclerislics. Theyoperote in the some circuits ond with lhe someequipmenl os equivolent wottoges of regulor fluores-cent lomps. BrileBlue
