I purchased this headlamp last year and it's still serving me well. If you like pure floodlights like the wizard this is a great alternate. If you don't mind coldish white tint around 5500k ish. On board micro usb charging works well and the rubber port cover (mine didn't come with a spare usb cover) still fits tight a year later (on average I open the port to charge about 4 times a month). Magnet at the base still going strong and comes in handy. Really nice for up close task.
planb10113Not sure about Petzl but I have a couple Black Diamond headlamps for running. In terms of durability and reliability in my opinion and experience the HL18 is comparable. For me its too heavy to be a running headlight but I have taken it caving a few times without babying it and no issues thus far.
mc84Do Petzl and Black Diamond even step into the 18650 world?
To my knowledge those are mostly ultralight type headlamps. This is more of an entry level head mounted Sun ray. 900 lumens is not impressive for an 18650 lamp, but the price is ok.
