FAQ
1. If the connection load less than 55% for the load limitation led driver, what will happen?
Answer: If you take our 1.0V triac dimmable led drivers, the led light will have flick problem.
2. Can we make our company information on the label?
Answer:
--As per the policy of ETL/UL, we can not make changes on the labels at liberty. If we make changes as your requirement , then our company will be punished if the ETL/UL department discover it . Really sorry for that and caused you so much trouble..
--If making changes on the labels are necessary for your company, I suggest you multi-list of our ETL/UL certification , then we can help you design the new label as requested.
