1. Usayizi omncane, ukushabalaliswa kokushisa kanye nokubola kokukhanya kuyizinkinga ezinkulu
I-Lightmanukholelwa ukuthi ukuze kuthuthukiswe isakhiwo se-filament sezibani ze-filament ze-LED, izibani ze-filament ze-LED okwamanje zigcwele igesi engasebenzi kahle yokushabalalisa ukushisa kwemisebe, futhi kukhona igebe elikhulu phakathi kokusetshenziswa kwangempela nomphumela wokuklama. Futhi, njengoba i-filament ye-LED iyi-chip ngesimo sephakheji ye-COB, ukusetshenziswa kwezinye izindlela zobuchwepheshe ezisebenzayo zokunciphisa ukukhiqizwa kokushisa noma ukuqhutshwa kokushisa okusheshayo kuyisiqinisekiso sokubola kokukhanya okuphansi kanye nokuphila isikhathi eside kwesibani se-filament se-LED, njengokwenza ngcono isimo se-substrate kanye nezinto ze-substrate. Ukukhetha, imodi ye-thermoelectric shunt, njll.

2. Ayikwazi ukuqeda ngokuphelele i-stroboscopic
Ngokuphathelene nenkinga yokukhanya kwe-stroboscopic kwezibani ze-LED filament, i-lightman ikholelwa ukuthi izibani ze-LED filament zincane ngobukhulu futhi zincane endaweni yokufaka. Isikhala sokufaka esilinganiselwe sinezidingo eziqinile kakhulu kumthamo wezingxenye, futhi okwamanje singasetshenziswa ngamandla aphansi kanye nendawo encane yokufaka. Ukukhanya okuphezulu komkhiqizo kuphela okuhlangabezana nale mfuneko. Ngenxa yomphumela "wembobo" obangelwa ukulingana okuphezulu kwamandla kagesi ekuhambeni okusheshayo kwamandla kagesi, kunzima kakhulu ukufeza i-stroboscopic flash ngamandla amakhulu okukhiqiza ngaphansi kwesisekelo sokuthi ubuchwepheshe bokunxephezela abunazo izindlela zobuchwepheshe ezinhle. Akukho nhlobo i-stroboscopic futhi akukho sixazululo esiphelele. Izindlela zobuchwepheshe kuphela ezingasetshenziswa ukunciphisa umphumela "wembobo" nokulawula i-stroboscopic ku-ext ethile.
