In the spring of 2016, a new and improved version of the Storm was made available. It is a nice upgrade that includes 56% more light output (now 250 lumens vs. 160), improved optics with a wider, smoother beam pattern, and is now dustproof as well as waterproof. More details below.
The Storm tied for 4th place in our overall performance scores with its sibling, the Black Diamond Spot. Compared to the Spot, the Storm costs $10 more, is a bit heavier (1 oz, for the addition of one more AAA battery), offers longer battery life, and is waterproof to 1 meter deep. Both the Storm and the Spot include a new Black Diamond feature called PowerTap, which lets you adjust brightness with the tap of a finger. While novel, we didn't feel PowerTap improved usability much. The Storm offers more lumens than the Spot, but we found it offered about the same performance for trail finding as the Spot and the other Editors' Choice winner, the Coast HL7. And, the ability of the Coast to see so much further was a factor in earning it the top score and Editors' Choice award.
In the end, we think there is much to love about the Storm, and if you need a solid, easy to use headlamp that is waterproof, it is your best option. But, if waterproof isn't crucial, we'd recommend you look closely at the Coast HL7 or the Black Diamond ReVolt before you buy.
