1. Te Rerenga o te Hiko (F)
Ko te tapeke o te pūngao e tukuna ana e te pūtake mārama, ā, e riro ana i ngā kanohi tangata, ko te rerenga mārama (wāhanga: lm(lumen)). I te nuinga o te wā, ko te teitei ake o te mana o taua momo rama, ko te nui ake o te rerenga mārama. Hei tauira, ko te rerenga mārama o te rama mura noa 40 he 350-470Lm, ko te rerenga mārama o te rama mura ngongo tika 40W he tata ki te 28001m, arā, 6~8 ngā wā o te rama mura.
2. Te Kaha o te Kanapa (I)
Ko te rerenga mārama e tukuna ana e te pūtake mārama i roto i te koki totoka kotahi i tētahi ahunga kua hoatu ka kiia ko te kaha mārama o te pūtake mārama i taua ahunga, ā, ka kiia ā-tika ko te kaha mārama (ko te waeine ko cd (kanera)), 1cd=1m/1s.
3.Te Whakamārama (E)
Ko te rerenga mārama e whiwhihia ana mō ia waeine o te horahanga e whakamāramahia ana e kiia ana ko te whakamārama (ko te waeine he 1x（lux）, arā, 11x=1lm/m². Ko te whakamārama whenua i te poutumarotanga me te hihi kaha o te rā i te raumati he tata ki te 5000lx, ko te whakamārama whenua i te rā paki i te takurua he tata ki te 20001x, ā, ko te whakamārama whenua i te pō marama mārama he tata ki te 0.2lX.
4.Te kanapa (L)
Ko te kanapa o te pūtake mārama i tētahi ahunga, ko te waeine ko nt (nits), ko te rerenga kanapa e tukuna ana e te waeine horahanga e whakaatahia ana me te waeine koki totoka o te pūtake mārama i taua ahunga. Mena ka kiia ia mea he pūtake mārama, ko te kanapa e whakaahua ana i te kanapa o te pūtake mārama, ā, ko te māramatanga e whakaaro ana i ia mea hei mea e whakamāramahia ana. Whakamahia he papa rakau hei whakaatu. Ina pā tētahi hihi mārama ki tētahi papa rakau, ka kiia ko te nui o te māramatanga o te papa, me te nui o te mārama e whakaatahia ana e te papa ki te kanohi tangata, ka kiia ko te nui o te kanapa o te papa, arā, ko te kanapa he rite ki te māramatanga e whakareatia ana ki te whakaata, i te wāhi kotahi i roto i te rūma kotahi, he wahi kakahu mā me tētahi wahi o te He rite te māramatanga o te mākete pango, engari he rerekē te kanapa.
5.Te Whaihua o te Pūtake Mārama
Ko te ōwehenga o te rerenga mārama katoa e tukuna ana e te pūtake mārama ki te mana hiko (w) e pau ana i te pūtake mārama ka kiia ko te Whaihua mārama o te pūtake mārama, ā, ko te waeine ko ngā lumens/watt (Lm/W)
6.Te Mahana Tae (CCT)
Ina tata te tae o te mārama e tukuna ana e te pūtake mārama ki te tae e tukuna ana e te tinana pango i tētahi pāmahana, ka kiia te pāmahana o te tinana pango ko te pāmahana tae (CCT) o te pūtake mārama, ā, ko te waeine ko K. He whero te tae o ngā pūtake mārama he pāmahana tae kei raro iho i te 3300K, ā, ka mahana te tangata. Ina neke atu te pāmahana tae i te 5300K, he kikorangi te tae, ā, ka mātao te tangata. Ko te tikanga, ka whakamahia ngā pūtake mārama he pāmahana tae neke atu i te 4000K ki ngā wāhi he teitei ake te pāmahana. Ki ngā wāhi iti iho, whakamahia ngā pūtake mārama kei raro iho i te 4000K.
7.Taupū Whakatakotoranga Tae (Ra)
Ka whiti te hihi o te rā me ngā rama mura i te whānuitanga tonu. Ka whakaatu ngā mea i ō rātou tae tūturu i raro i te hihi o te rā nui me ngā rama mura, engari ina whakamāramahia ngā mea e ngā rama tuku hau whānuitanga korekore, ka rerekē ngā nekehanga o te Whakapōturitanga o te tae, ko te nekehanga o te pūtake mārama ki te tae tūturu o te mea ka huri hei whakaputanga tae o te pūtake mārama. Hei ine i te whakaputanga tae o te pūtake mārama, ka whakaurua te ariā o te taupū whakaputanga tae. I runga i te mārama paerewa, ka tautuhia te taupū whakaputanga tae ko te 100. Ko te taupū whakaputanga tae o ētahi atu pūtake mārama he iti iho i te 100. Ko te taupū whakaputanga tae ka whakaatuhia e Ra. Ko te nui ake o te uara, ko te pai ake o te whakaputanga tae o te pūtake mārama.
8.Te Ora Toharite
Ko te roanga ora toharite e pā ana ki te maha o ngā hāora e kā ana te 50% o ngā rama i roto i tētahi puranga rama ina pakaru.
9.Te roanga o te oranga ōhanga
Ko te roanga o te ora e pā ana ki te maha o ngā hāora e whakaitihia ana te putanga hihi whakauru ki tētahi ōwehenga, me te whakaaro ki te kino o te pūrama me te whakaiti i te putanga hihi. Ko te ōwehenga he 70% mō ngā pūtake mārama o waho, me te 80% mō ngā pūtake mārama o roto.
10.Te Whaihua o te Kanapa
Ko te whai huatanga o te kanapa o tētahi pūtake mārama e pā ana ki te ōwehenga o te rerenga kanapa e tukuna ana e te pūtake mārama ki te mana hiko P e pau ana i te pūtake mārama.
11.Mārama kanapa
Ina tino kanapa ngā mea i te tirohanga, ka kore e pai te tirohanga, e kiia ana he mārama kanapa. He mea nui te mārama kanapa e pā ana ki te kounga o ngā pūtake mārama.
