This torch is very very bright. It runs off of 4 18650 batteries. This is a snub style light but is still plenty bulky. Definitely not for ultralight camp our hike. Perfect for normal camping and hiking or just to use around the house or in the car. It has 3 different modes. Very bright, very very bright and strobe. Not sure i will every use strobe but may be useful in emergencies. All around a solid, well built, durable and ultra bright torch.
