Ngokuvuthwa kobuchwepheshe be-LED, i-lumen ephezulu ephumayo ehola ishubhu kancane kancane ijwayele ukubonakala, ngakho-ke imakethe ilindele okwengeziwe ngamandla aphansi kodwa ngemikhiqizo ephezulu kakhulu yokukhipha i-lumen.

NgoSepthemba 2013, isikhulu esikhanyisayo sase-Japan i-Endo Lighting siphakamisa ishubhu le-LED elisebenza kahle ngokukhanya kwe-lumen okungu-140lm/W, okudale ukuqhuma kwengxoxo nokushaya ihlombe!Nakuba ukusebenza kahle kwe-lumen kwe-chip ye-LED kuye kwanda kakhulu ezikhathini zamuva, kodwa ukusebenza kahle kwe-lumen kwe-LED enjalo kuyamangalisa abantu abaningi.

Kamuva cishe ngemva kwenyanga, i-PVTECH evela e-Xiamen China yenza isiphakamiso seshubhu le-LED elino-145lm/W lokusebenza kahle kwe-lumen.Le tube ye-LED ingabizwa ngama-artifacts embonini ye-LED.

Kulula ukwenza ukukhanya okuphezulu kwe-lumen uma wengeza amanani e-chip ye-LED.Kodwa idizayini yesakhiwo enengqondo kuphela kanye nomshayeli osebenza kahle kakhulu ukuhlangana ndawonye kungabona ukusebenza kahle kwe-lumen kweshubhu le-LED.Lokhu kuphinde kubonise ukuthi ubuchwepheshe be-LED yezwe lase-China vele bungaphezu kobe-Taiwan ne-Korean, futhi busondela kuLobo base-Japan.
