What it's good for
Flood to spot
Slide the head to go from lighting a whole room to throwing a narrow beam down the garden.
Five modes
High, low, strobe, flood and focused. The strobe is on the same button cycle, so you pass through it.
Cheap enough to keep three
One in the car, one by the fuse box, one in the camping bag. That's the right way to own a torch.
