Hiki mai nā kukui lalo i nā ʻano nui like ʻole e kūpono i nā hiʻohiʻona noiʻi like ʻole a me nā koi hoʻolālā. Eia kekahi mau laʻana maʻamau:
Nā kukui pōʻai lalo:
ʻO nā anawaena maʻamau ka Φ50mm, Φ65mm, Φ80mm, Φ100mm, Φ150mm, Φ180mm, a me Φ200mm.
ʻO ke kiʻekiʻe maʻamau mai 45mm a 250mm.
Nā kukui lalo honua huinaha:
Loaʻa nā nui mai kahi liʻiliʻi 100x100mm a hiki i kahi 300x300mm nui.
ʻO ka mānoanoa maʻamau mai 50mm a 90mm.
Nā kukui ma lalo o ka honua ʻehā:
'Oko'a ka lō'ihi-a-elike me 200x80mm, 300x90mm, 600x100mm, a me 1000x100mm.
ʻO ke kiʻekiʻe maʻamau mai 60mm a 70mm.
Nā kukui ma lalo o ka honua i hoʻohālikelike ʻia:
Ma waho aʻe o nā ʻano poepoe a me nā ʻano huinaha maʻamau, aia kekahi mau kukui maʻamau -lalo o ka honua, e like me nā ʻano curved a polygonal, i hana ʻia i nā pono kikoʻī.
Pili kēlā me kēia nui i nā wattage like ʻole a me nā hiʻohiʻona noi. No ka laʻana, kūpono paha kahi kukui liʻiliʻi ma lalo o ka honua no ka hoʻomālamalama ʻana i kahi wahi liʻiliʻi e like me ke alahele a i ʻole ka lihi o kahi moena pua; ʻoiai hiki ke hoʻohana ʻia kahi mea nui no nā wahi nui e koi ana i ka mālamalama ikaika, e like me nā plaza a me nā wahi kaʻa.
Eia kekahi, ʻo ka nui kikoʻī o ke kukui o lalo e pili pū i ka nui o ka wehe (ʻo ia ka nui o ka lua i mālama ʻia i ka lepo), he mea koʻikoʻi no ka hoʻokomo ʻana. ʻO ka hōʻoia ʻana ua koho ʻia ka nui kūpono o ke kukui ma lalo o ka honua a ua ana pono ʻia nā ana wehe ʻana a hoʻomākaukau ʻia nā mea e pono ai no kahi hoʻonohonoho maʻalahi.
