I got mine wet, maybe if dropped under water and zoomed is bad, We don't have to guess. Duracell rates the light as IPX4. The X instead of a digit in the first place means it's not tested for solid object intrusion, which many lower priced lights aren't. The 4 in the second place is the water resistance rating. 4 is resistant to splashing. 5 is light jetting, 6 is strong jetting, 7 is temporary submersion, and 8 is submersion up to 2 meters. IPX4 is a long way from even temporary submersion. It may be enough for your uses, but similarly priced lights with better performance are rated at IPX7 or IPX8. otherwise the zoom feature is super I still disagree with that. Duracell rates your light at 22,500cd. The $20 Astrolux C8 is rated at 102,000cd. Add in a $3 diffuser (similar to the old traffic wand attachments) and you have the flood / lantern capability without giving up the IPX8 rated water proofing. Yes, you'll have to add a $5/$6 rechargeable battery and a $4 charger. c cells last a long time and are cheap. Yes and no. A typical alkaline c cell has an 8,000 mAh capacity. That's 8 amp hours x 1.5 volts = 12 watt hours. A good 18650 battery is 3,500 mAh and 3.7 volts. That's 3.5 amp hours x 3.7 volts = 12.95 watt hours. BUT, because lithium cells can maintain high current discharge throughout their voltage range, they can maintain high total output. Alkaline can't do that. So, those $6 a piece 18650 batteries and their $4-$10 charger become more economical after only a few uses. Then there's the battery chemistry issue, or why flashlight nerds call alkalines "alkaleaks". Alkalines use a wetter chemistry than NiMH or the various lithium chemistries. The potassium hydroxide electrolyte in alkalines is also caustic, which further compounds their tendency to leak. In other words, be very careful storing a flashlight with alkalines in your car, especially in warmer months. While the new LED Maglights are better than ever , they don't perform like that Cheap Duracell 1000 IMHO. In the context of a light that can also function as an improvised club, then these Duracells may indeed be a good value. Purely as a flashlight, I'm not sure. And that's what's important.
