LED Driver is from  MEAN WELL ENTERPRISES CO LTD(E334687 on the UL R/C Product). It provided with integral input and output cord. 

This LED driver model is HBG-100-48E. 100-240/277, 50/60Hz, 1.1/0.45A, LVLE, 49 Vdc, 2.0 A, use for WET Location.

In the United state, From the UL 1598 and UL 8750 Lighting standard, the diffuser must have f1! Since factory claimed it has earned UL Certificated. It may be had, but please be awarded there is trick for this. We can call this liar. 

If you want to go into details, in fact, I hope you can do it. You can required the factory to provide the UL Report to you, you can check in detail, and verify it in the UL.com.
