Hi -- the Lezyne Fusion Drive Pro 600+ Front Light is a good option. It has six settings (which is good), well engineered and strong, the smallish size in length and width is great, and the face of the light (5-led bulbs) gives good viability during the day and when I use it at night (which is often). This light is bright enough at night -- I never use the 600 lumen setting.
I am not a fan of the way this light attaches to the handle-bars, because you have to unhook the whole light in order to recharge it. I commute 5-days a week and find myself recharging this light about every 2.5 weeks.
Have used this over the past few months and very impressed. No complaints, was thinking about getting another one.
Does what it's supposed to do. Not much else I can say. I would but again.
Features of the Lezyne Fusion Drive Pro 600+ Front Light are spot-on. Bumpy conditions cause the light to rotate changing the beam level. Easy to reposition though.
