How is Fenix HL-20 with Diffuser?

[Bolster]

How is the Fenix HL-20 with the diffuser in place...does the diffuser work...is it durable...does it give a flat even flood, or does it still have a hot-spot in the center?



I have a Zebralight H-50, with a 120-degree flood...how would it compare to that?



Thanks.
