I’ve got a Petzl Nao (575 lumens)
Used to have a Alpkit Gamma before that.
To be honest best bit of outdoor kit I’ve bought. For biking the £40 Chinese light is great for running this is something else.
Very well balanced on the head, the reactive lighting really does work well and it lasts ages. One light does light spread, the other does distance. eg running along only the spread light comes on, if you look in to the distance to see where a path goes, the spot distance light spots stuff probably up to about 100ft away.
Friends of mine have been through various cheaper options, and never really got what they wanted.
