ʻO ke kukui incandescent kahi ʻano kumu kukui uila e hoʻomehana a ʻālohilohi i ke alakaʻi ma hope o ke kahe ʻana o ke au ma o ia mea. ʻO ke kukui incandescent kahi kumu kukui uila i hana ʻia e like me ke kumumanaʻo o ka radiation thermal. ʻO ke ʻano maʻalahi o ke kukui incandescent, ʻo ia ke hoʻouna i ke au lawa ma o ka filament e hoʻolilo iā ia i incandescent, akā he pōkole ke ola o ke kukui incandescent.
ʻO ka ʻokoʻa nui ma waena o nā kukui halogen a me nā kukui incandescent, ʻo ia ka hoʻopiha ʻia ʻana o ka pūpū aniani o ke kukui halogen me kekahi kinoea elemental halogen (ʻo ia hoʻi ka iodine a i ʻole bromine), e hana ana penei: Ke wela ka filament, ua mahu ʻia nā ʻātoma tungsten a neʻe i ka paia o ka paipu aniani. Ke hoʻokokoke aku lākou i ka paia o ka paipu aniani, ua hoʻomaʻalili ʻia ka mahu tungsten i kahi o 800 ℃ a hui pū me nā ʻātoma halogen e hana i ka tungsten halide (tungsten iodide a i ʻole tungsten bromide). Ke hoʻomau nei ka tungsten halide e neʻe i waenakonu o ka paipu aniani, e hoʻi ana i ka filament oxidized. No ka mea, he hui paʻa ʻole ka tungsten halide, ua hoʻomehana ʻia a ua hoʻoheheʻe hou ʻia i loko o ka mahu halogen a me ka tungsten, a laila waiho ʻia ma luna o ka filament e hana no ka mahu ʻana. Ma o kēia kaʻina hana hou ʻana, ʻaʻole wale ka hoʻolōʻihi nui ʻia ʻana o ke ola lawelawe o ke filament (ʻaneʻane 4 mau manawa o ke kukui incandescent), akā no ka mea hiki i ka filament ke hana i kahi mahana kiʻekiʻe aʻe, no laila e loaʻa ai ka ʻōlinolino kiʻekiʻe, ka mahana kala kiʻekiʻe a me ka pono luminous kiʻekiʻe.
He mea nui ka maikaʻi a me ka hana o nā kukui kaʻa a me nā kukui no ka palekana o nā kaʻa, ua hoʻokumu ko mākou ʻāina i nā kūlana aupuni e like me nā kūlana o ka ECE ʻEulopa i ka makahiki 1984, a ʻo ka ʻike ʻana i ka hana hoʻolaha mālamalama o nā kukui kekahi o nā mea nui loa i waena o lākou.
