 Quick Details

Description
 
1 . Guarantee is for 2 years .
2 . The average lifetime of our LED bulb is at least 30 000h .
3 . Living up to the IEC62031 : 2008 & 62560 standard .
4 . Saving 90% electricity compared to traditional incandescent bulbs or Energy saving lamps .
5 . Can start under the condition of - 30 ℃ and low voltage .
6 . No flicker , No noise , No electromagnetic interference ( EMI ) .
8 . 200 pcs SMD 2835 Chip 0.2W ,Epistar / Bridgelux .
9 . Using pure 6063 Aluminum cover , haveing excellent heat conduction ,160 W / ( m.K ) .
10 . Using nickleplated aluminum base , very good to avoid getting rusted .
11 . For the pack , we have color box , single blister , double blister .
12 . We choose very good driver supplier like Meanwell,mosopower to have constact current output to the LED chip , which is also safe .
13 . Easy to apply , can change traditional incandescent bulbs and CFL bulbs directly , saving more energy and having longer life .
14 . All products are output strictly under ISO 9001 Quality Management System and CE satisfied .
15 . Voltage : all of our LED products supply wide range voltage input .
 

 
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 .
5 . In the warehouse , our QCs will take sampling inspection before load the container , if not qualified with the AQL , we will rework .
6 . 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 .
 
Trade terms

1 . Payment term : T/T , 30% deposits in advance , 70% balance before shipment .
2 . Samples can be provided for free , but the express fee need to be payed for the first time , and can be returned after placing the first order .
