A'oa'o e uiga i le Apogee SQ-640 Quantum Light Pollution Sensor ma ona fa'aoga i totonu o siosiomaga i lalo ole LED. O le tusi lesona a lenei tagata e aofia ai foliga, faʻamatalaga faʻapitoa, ma taʻiala faʻaoga o le SQ-640 faʻataʻitaʻiga. Maua sa'o fua fa'atatau o le fe'avea'i o photon fa'atasi ai ma lenei fa'ata'ita'i fa'aopoopo fa'atele.
A'oa'o e uiga i le Quantum Light Pollution Sensor - Fa'ata'ita'iga SQ-647 mai Apogee Instruments, Inc. O lenei fa'alauteleina o le PFD sensor e fa'amalieina fa'atonuga a le EMC ma le RoHS. Saili aoga o le fuaina o fa'avevela fa'a photosynthetically fa'atasi ai ma lenei fa'ailoga fa'aleaga.
Ia maua le mea sili mai lau Apogee Instruments' SQ-644 Quantum Light Pollution Sensor ma lenei tusi lesona a le pule. E tusa ai ma tulafono a le EU, o lenei tusi lesona e aofia ai vaega uma o le faʻaogaina o le SQ-644 e fua ai faʻamalositino faʻamalositino faʻamalositino ma mataʻituina le filogia o le malamalama.
O lenei tusi fa'aoga e maua ai fa'atonuga mo Apogee SQ-642 ma SQ-645 Quantum Light Pollution Sensors. O oloa e ogatasi ma fa'atonuga a le EU ma e le o iai ni mea mata'utia. O lo'o fa'apipi'i fo'i i le tusi lesona le fuaina o fa'avevela fa'aola fa'a photosynthetic ma ona a'afiaga i tali atu i la'au.
