I would look at the Fitorch ER16. It will take 18350’s along with cr123’s. It doesn’t say it in the description but 18350 fits. Just makes it more versitle. 1000 lumens and usually on sale for $25.99 @ gearbest. Look on the Gearbest deals on this forum if it is not on sale and you can get a code there. Uses an XP-L2 emitter.
