FAQ
1. what is the HS code for this Power supply?
Answer: HS code is 8504401400.
2. If we found any defective products within warranty ,what Smarts should us do for the defective product ?
Answer: We give 3 years warranty for dimmable led driver. If clients use properly, hardly any of feedback from our clients about the led drivers can not work or damaged during warranty time..
If you have received feedback about defective led driver from your clients, pls. ask your engineer help us verify the things as following:
--What kind of led light they used ?? What specifications of this led light?? output power / output voltage / output current??
--Check the label and ensure the driver has the proper input voltage and wattage for the job. Pls. not install overload / overvoltage / overcurrent. That will great damage lifetime of led drivers.
--Do clients have correct connection? and if they use proper dimmer ?
--what is environment temperature when led driver working on?
Install only in dry or damp locations. Do not install in wet locations. / Install in a well-ventilated area free from explosive gases and vapors.
--How long does the led drivers working everyday? Do not let the led drivers working 24/7(24hours and a week).
