...I would prefer the output to be frosted....
If they want to offer both a plain lens and a frosted lens, that is fine with me--more options for us!
But to my mind, this is a case where DC Fix does everything I would want from a frosted lens, and is removable, so I get both options with one light.
I have an H602 on my front handle-bars with DC Fix on the lens both to diffuse the light and to widen the cone a bit. Seems to work.
I will say that I'm a bit disappointed that they are still using the XP-E, because it does not seem to be a very efficient emitter for red light. I had a Quark RGB with a four-die MCE, and it put out a lot of red light for a long time. The XP-E has a very small die, so it is still good for making small lights (like AAA format lights) throwier than they would be with a larger die. But in a pure flood light, the small-die emitter is no advantage. Isn't there some other emitter, with any size die, that would give better efficiency for red light?
