Amfanin hasken hanya na LED a cikin hazo da ruwan sama za a iya nuna su ta fuskoki uku:
1. Alkiblar da ke tattare da hasken da aka fitar;
2. Halayen tsayin raƙuman ruwa na fararen LEDs;
3. Mitar wannan tsawon tsayi idan aka kwatanta da sauran hanyoyin haske.
Bambancin da ke tsakanin hasken LED da duk sauran hanyoyin haske shine mafi girman tsayin da yake fitar da makamashi, da kuma yadda digogin ruwa ke hulɗa ko shafar hasken a wannan tsayin daka, musamman yayin da girman digogin ruwa ke canzawa.
Hasken da ke fitar da makamashin haske a cikin raƙuman shuɗi na bakan da ake iya gani, kamar LEDs, suna aiki mafi kyau fiye da sauran hanyoyin haske a cikin yanayin da ba a iya gani sosai.
Haske a yankin shuɗi na kewayon spectral yana da gajeriyar tsawon tsayi fiye da haske a yankin ja.

Daga girman barbashi na ruwa zuwa tsawon tsayi, fitilun hanya na LED sune mafi kyawun zaɓi don yanayin rashin gani. Zafin launi da ƙirar haske suna ƙirƙirar mafi kyawun yanayin hanya yayin ruwan sama da hazo. Ta hanyar inganta gani, fitilun hanya na LED suna kiyaye hanyoyi lafiya a cikin ruwan sama da yanayin hazo.
Idan kuna sha'awar hasken hanya na LED, barka da zuwa tuntuɓar masana'antar hasken hanya ta LED TIANXIANG zuwakara karantawa.
