LED Bulb Lights 3W E27 IC Driver E27 Base LB-60A3W-1 30 000 Life Time
Description
1 . All products are output strictly under ISO 9001 Quality Management System and CE satisfied .
2 . SMD 2835 Chip 0.2W .
3 . Can start under the condition of - 30 ℃ and low voltage .
4 . Passing the EMC test .
5 . Using nickleplated aluminum base , very good to avoid getting rusted
6 . Using PBT plastic plus Aluminum cover which two advantage :
1 ) haveing good heat diffusion and conduction
2 ) Safe , can using non isolated power supply
3 ) Cheap
7 . Guarantee is for 2 years .
8 . We choose very good driver supplier like Meanwell,mosopower to have constact current output to the LED chip , which is also safe .
9 . Living up to the IEC62031 : 2008 & 62560 standard .

Quality Control ( QC )
1 . Strict raw materials inspection .
2 . Technical parameter adjustment :
1 ) Technicians will tune the technical parameters of each items to make sure the Wattage , P.F.living up to the requirement of customer
2 ) Destructive test , light it in the oven to be under the conditions of high temperature and high voltage
3 ) Turn on off test , to make sure the life time of the lamp
4 ) Start test in low temperature and low voltage ( light in the fridge )
3 . we are testing every lamp before packed in the cartons .
4 . After laoding the container , we will trace the life time of ech order , we will pick 10 pcs of each item to light in the ageing room till the lamp die , so we can trace down the real life time of each order .
Application
Widely used in home & commercial Lighting , always using together with the downlight fixtures , applying in office , Hallway , Hotel , room , shop , ect .
