1. Te rahi iti, te wera wera me te pirau marama he raruraru nui
Maamaawhakapono e ki te whakapai ake i te hanganga kakawaea o rama kakawaea arahina, kua ki tonu i tenei wa rama kakawaea arahina ki hau inert mo te tohanga wera radiation, a reira he he āputa nui i waenganui i te tono tūturu me te pānga hoahoa.Ano hoki, i te mea he maramara te kakawaea LED i te ahua o te kete COB, ko te whakamahi i etahi tikanga hangarau whai hua hei whakaiti i te whakaputanga wera me te tere o te waiariki he tohu mo te pirau marama iti me te roa o te ora o te rama kakawaea LED, penei i te te arotautanga o te ahua o te tïpako me te rauemi tïpako.Te kowhiringa, te aratau shunt thermoelectric, etc.

2. Kaore e taea te whakakore rawa i te stroboscopic
Mo te raruraru o te stroboscopic rarapa o rama kakawaea arahina, whakapono Lightman he iti i roto i te rahi me te iti i roto i te wāhi tāutanga rama kakawaea arahina.Ko te iti o te waahi whakaurunga he tino kaha nga whakaritenga mo te rahi o nga waahanga, a ka taea te whakamahi i tenei wa me te iti o te mana me te waahi whakaurunga iti.Ko te ahorangi teitei anake o te hua ka tutuki tenei whakaritenga.Na te kaha o te "poka" i puta mai i te raina ngaohiko teitei i roto i te tere tere o te waa, he tino uaua ki te whakatutuki i te stroboscopic flash i roto i te kaha o te whakaputa nui i raro i te whakaaro ko te hangarau utu kaore he tikanga hangarau pai.Kaore rawa he stroboscopic, kaore he otinga tino.Ko nga tikanga hangarau anake ka taea te whakamahi hei whakaiti i te paanga "poka" me te whakahaere i te stroboscopic ki tetahi atu
