Ko te rama mura he momo pūtake rama hiko e whakamahana ana, e kanapa ana hoki te kaiārahi hiko i muri i te rere o te iahiko mā roto. Ko te rama mura he pūtake rama hiko i hangaia i runga i te mātāpono o te irahiko wera. Ko te momo rama mura māmā rawa ko te tuku i te iahiko nui mā roto i te miro kia mura ai, engari he poto te ora o te rama mura.
Ko te rerekētanga nui i waenga i ngā pūangi halogen me ngā pūangi incandescent ko te whakakīia o te anga karāhe o te rama halogen ki te hau halogen (ko te tikanga he iodine, he bromine rānei), e mahi ana penei: I te wera o te miro, ka mimiti ngā ngota tungsten ka neke ki te pakitara o te ngongo karāhe. I a rātou e whakatata atu ana ki te pakitara o te ngongo karāhe, ka whakamataohia te mamaoa tungsten ki te 800℃ ka honoa ki ngā ngota halogen hei hanga i te halide tungsten (tungsten iodide, tungsten bromide rānei). Ka haere tonu te neke o te halide tungsten ki waenganui o te ngongo karāhe, ka hoki ki te miro kua waikurahia. Nā te mea he matū tino kore pumau te halide tungsten, ka whakamahanahia, ka pirau anō hei mamaoa halogen me te tungsten, ka whakatakotoria ki runga i te miro hei whakakī i te mimiti. Mā tēnei tukanga hangarua, ka roa ake te ora o te miro (tata ki te 4 ngā wā i tērā o te rama mura), ā, nā te mea ka taea e te miro te mahi i te pāmahana teitei ake, ā, ka nui ake te kanapa, te pāmahana tae me te pai o te kanapa.
He mea nui te kounga me te mahi a ngā rama me ngā rākau waka mō te haumaru o ngā waka, i te tau 1984 i whakatakotohia e tō tātou whenua ngā paerewa ā-motu e ai ki ngā paerewa o te ECE Pākehā, ā, ko te kimi i te mahi tohatoha mārama o ngā rama tētahi o ngā mea tino nui o aua paerewa.
