We have a Storm and an earlier Spot in our camping family. This new version of the Spot rocks, more lumens, seriously bright on high, but quite enough light around camp on low. The lock feature ensures the light cannot turn on in your pack/backpack and drain the battery, a big problem without that feature. The redesigned battery door is a nice change, too. The last one you were afraid of breaking it, tough to get into, and impossible with gloves on for winter hiking.
My favorite feature by far, though is the Power Tap. It's not really a tap, but one good touch on the Power Tap on the side of the unit toggles the light from high to low, and back with another touch. A VERY useful feature in camp. The design is a bit boxy, not as futuristic as the Storm, but I believe it's the same light output for $10 less, and this Spot light is all you really need. Plenty of usable light.
