I've been looking for a better front light for unlit roads, cyclepaths and towpaths (my current one is great for making me visible to other road users but not so good for avoiding potholes or the canal!).
This one has a 3 hour battery life in High Mode (400 lumens) and up to 60 hours in flashing mode.
USB rechargeable battery is removable so you can carry a spare.
I already have a Cateye light so this'll slot into the same bracket (and my old one becomes a spare).
High mode 400 lumens： 3hrs
Middle mode 100 lumens： 8hrs
Low mode 50 lumens：18hrs
Hyper Constant mode 400/50 lumens：11hrs
Flashing mode 50 lumens： 60hrs
RRP is £60 I can't find it for less anywhere else.
Don't confuse this with the lower spec 400XC.
2.1% Quidco and probably TopCashBack too.
