A LED-lámpák minősége elsősorban több paramétertől függ:
1. Fénycsillapítás, a jobb LED-lámpák fénycsillapítással rendelkeznek<30% before="" 25000="" hours;="" led="" street="" light="" housing="" ,led="" flood="" light="" housing="" ,100w="" led="" street="" light="" supplier="" and="" factory="" in="" china;="" 2.="" luminous="" efficiency,="" which="" is="" the="" number="" of="" lumens="" per="" watt,="" in="" lm/w.="" it="" reflects="" the="" energy-saving="" performance="" of="" the="" lamp.="" the="" better="" the="" energy-saving="" lamp,="" the="" higher="" the="" luminous="" efficiency.="" with="" the="" improvement="" of="" led="" luminous="" efficiency,="" cree="" may="" produce="" 186lm/w="" light="" source="" this="" year.="" led="" streetlight="" ,="" ip66="" led="" street="" light="" empty="" casing="" factory="" in="" ningbo;="" 3.="" the="" light="" source="" is="" high-power="" led,="" straw="" hat="" lamp="" or="" piranha-type="" led;="" led="" lighting="" fixtures="" use="" high-power="" led="" as="" the="" light="" source,="" and="" the="" price="" is="" relatively="" high;="" while="" the="" price="" of="" straw="" hat="" lamp="" or="" piranha-type="" led="" is="" very="" cheap="" and="" not="" suitable="" for="" lighting="" the="" light="" source="" of="" class="" lamps.="" led="" tunnel="" light="" ,200w="" led="" floodlight="" ,100w="" led="" road="" lighting.="" 4.="" drive="" power.="" a="" good="" drive="" power="" can="" guarantee="" the="" life="" of="" the="" overall="" lamp.="" the="" theoretical="" life="" of="" led="" is="" 100,000="" hours="" while="" the="" life="" of="" general="" drive="" power="" is="" less="" than="" 100,000="" hours;="" in="" order="" to="" ensure="" the="" life="" of="" the="" overall="" lamp,="" the="" drive="" power="" is="" also="" a="" key="" part;="" on="" the="" one="" hand,="" the="" led="" must="" be="" driven="" by="" a="" constant="" current,="" if="" a="" low-cost="" constant="" voltage="" drive="" is="" used,="" the="" life="" of="" the="" led="" will="" be="">
