I've had both bike specific lights and flashlights.

My former Fenix BC30 bike specific lights had no hotspot, all the light is nearfield, couldn't see much beyond 5 meters or so, great off road, not so great for dark roads at higher speeds.

I use a Fenix LD50 (discontinued) as my main light, I vastly prefer having a nice 2-3 meter hotspot 20-30 meters ahead to focus on.

Removeable batteries are better than something that isn't user replaceable.

LED technology hasn't improved that much in the past few years it seems, and I have a stash of batteries and lights that are still quite effective.
