SKILHUNT M200 Rechargeable LED Flashlight for EDC, Powerfule, Waterproof, use for Outdoor, Rescue, Searching, Hiking and Emergency (High CRI 5000K, Brown)

very good, for 21700 w built in charging the Skilhunt M300 may be worth considering https://www.amazon.com/SKILHUNT-M200-Rechargeable-Flashlight-Waterproof/dp/B0FKT11J6B/ if you buy from Amazon it is easy to return for refund if you dont like it, you might be able to contact the seller to add a spare battery to your order it is important to buy the battery from the seller of the light (they use a button top), otherwise you might order one with the wrong type of positive contact (flat top), that wont work I recommend the High CRI LED, as it will show colors more accurately
