Little thread resurrection - nearly that time of year.
Roll on three years (wow that long) and I'm still using the NewBoller light with the beam cut off - really good on shared paths - essential on my route TBH as it's heavily used by pedestrians and cyclists.
I've just invested in a new Magicshine HORI 1300 (they do a 900 as well) which consists of a main 'dipped' LED and a 'Spot' for dark areas. Chucked in is a remote, so it's one press to access the spot beam. The dipped beam has a really good cut off with no light spill. The LED 'bulb' is actually a rectangle, so you get a wide spread, and spill onto the road below the bike
Biggest plus point it it uses Garmin style mounts and the go-pro connections using the supplied out front mount.
Magicshine did do another light, the Evo1300 for commuting, but there are many reports of broken mounts, this new light uses replaceable garmin brackets.
