Small single 18650 form factor and sustainable high output just does not compute. The best sustainable output you can expect from such tube like lights is around 600-800 lumens - nothing to brag about.
However if you can live with a 15-30 seconds real bright turbo, then Emisar D4V2 is probably one of the best these days - and it may even help if you need to start a fire somewhere lost in the deep forest, although it still has to be demonstrated.
