FAQ
1.What is the difference between the 20w/45w UL and 24w/48w ETL model?
Answer:
-- when you install a 20w/45w UL led driver in your led light you should consider abbot min. 55% load limtation. If it less than 55%, the led light will have flick problem. But the 20w/45w ETL model is no load limitation. You can load it in the led light 1-48w.
-- the height of 24w(20mm)/48w(24mm) is lower than 20w(28mm)/45w(34mm).
2.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
3. What is the shipping way do you have?
Answer:
--By air, by sea.
