I wouldnt recommend the Lezyne 400xl, it claims its 400 lumens, but my older light which was a mere 150lumens, outshines it in terms of distance at least, I get the spectral pattern might be different as its a different shaped light and so on, but it feels really dim in comparison, the only reason I got it is my older light the rechargeable battery is end of life and I cant replace it.
also the strap that you use to attach the 400xl to the bike snapped when I took it off to recharge it today...Ill have to jury rig some kind of thing with cable ties I reckon, but then you search on line and find the sell these straps for £5, like ok I get its nice to have spare parts for lights, but doesnt the propensity of their availablity, like every online bike shop seems to sell them, as a spare part kind of suggest its not up to the flippin job in the first place.
