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 . In the mass production , our QC will take selective examination
on every step , such as Plug-in , Wave soldering , PCB test , Tube
glue , Assembly , Print , Ageing , Packing .
4 . we are testing every lamp before packed in the cartons .
Application
Widely used in home & commercial Lighting , applying in office
, Hallway , Hotel , room , shop , ect .
