At least in my experience with two flashlights, the zoomable is not so good: when zoomed in, obviously it doesn't light far enough to see the road; but when zoomed out, it's too concentrated and does not light enough area. The intermediate zooming is not good in either aspect. In comparison, my flashlight without zoom feature lights both far and wide. Is this a general case? If so, I'll eliminate zoomables in my future purchases.
