What is the difference between the UL listed 20w/45w triac dimmable power supply and 24w/48w ETL listed power supply?

45w triac dimmable led drivers

when you install a 20w/45w UL led driver in your led light you should consider about min. 55% load limtation. If it less than 55%, the led light will have flick problem. If the connection load less than 55% for the load limitation led driver, what will happen?If you take our 1.0Version 45w triac dimmable led drivers, 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.


Also, regarding to the height for this two type, the height of 48w(24mm) is lower than 45w(34mm).

Last but not least, the pricing of the 48w led driver would be more favorable than 45w.
