Iyada oo bislaada tignoolajiyada LED-ka, tuubada wax-soo-saarka lumen ee sare waxay si tartiib tartiib ah u noqotaa mid caadi ah in la arko, markaa suuqyadu waxay filayaan wax badan oo awood hoose ah laakiin leh wax soo saarka lumen oo aad u sarreeya.

Bishii Sebtembar 2013, magnate-ka Japan Endo Lighting ayaa soo jeediyay tuubo LED ah oo hufnaankeedu yahay 140lm/W, taas oo sababtay buuq iyo sacab!In kasta oo waxtarka lumen ee chip-ka LED uu aad u kordhay wakhtiyadii dhawaa, laakiin hufnaanta sare ee lumen ee tuubada LED ayaa sidoo kale ka yaabisay dad badan.

Ka dib hal bil ka dib, PVTECH oo ka socota Xiamen China waxay soo jeedinaysaa tuubo LED ah oo leh 145lm/W waxtarka lumen.Tuubada LED-ka waxa loogu yeedhi karaa artifacts in industry LED.

Way fududahay in la sameeyo waxtarka lumen sare marka lagu daro tirada chip LED.Laakiin kaliya naqshad qaab dhismeedka macquulka ah iyo darawalka hufnaanta sare leh ee wadajirka ah ayaa ogaan kara waxtarka lumen sare ee tuubada LED.Tani waxay sidoo kale muujinaysaa in tignoolajiyada LED-ga dhul-weynaha Shiinaha ay mar horeba dhaaftay tii Taiwan iyo Kuuriya, oo ay ku soo dhawaatay tan Japan.
