Me ka ulu ʻana o ka ʻenehana LED, ua maʻa mau ke kiʻekiʻe lumen output led tube e ʻike, no laila ke manaʻo nei ka mākeke no ka mana haʻahaʻa akā me nā huahana lumen kiʻekiʻe.

I Sepatemaba 2013, ua hoʻolaha ʻo Endo Lighting i nā kukui kukui o Iapana i kahi paipu LED me ka maikaʻi o ka lumen o 140lm/W, kahi i hoʻohālua ʻia ai ke kūkākūkā a me ka paʻi!ʻOiai ua hoʻonui nui ʻia ka maikaʻi o ka lumen o ka chip LED i kēia manawa, akā ʻo ia ʻano kiʻekiʻe o ka lumen maikaʻi i ka pahu LED e kāhāhā nei i nā poʻe he nui.

Ma hope ma kahi o hoʻokahi mahina ma hope mai, hoʻolaha ʻo PVTECH mai Xiamen China i kahi pahu LED me 145lm/W o ka pono lumen.Hiki ke kapa ʻia kēia paipu LED i nā artifacts i ka ʻoihana LED.

He mea maʻalahi ke hana i ka pono lumen kiʻekiʻe ke hoʻohui i nā nui chip LED.Akā ʻo ka hoʻolālā hoʻolālā kūpono wale nō a me ka mea hoʻokele maikaʻi kiʻekiʻe e hui pū i hiki ke ʻike i ka pono lumen kiʻekiʻe no ka pahu LED.ʻO kēia ka mea e hōʻike ana ua ʻoi aku ka ʻenehana LED ma ka ʻāina ʻo Kina ma mua o Taiwan a me Korea, a hoʻokokoke i kēlā o Iapana.
