Streamlight 88081 ProTac HL 5-X USB 3500-Lumen Rechargeable Tactical Flashlight with 2 SL-B26 Battery Packs, Dual USB Cord & Wrist Lanyard - High-Intensity LED for Outdoor, Camping, Hunting & Emergency Use - Black (Box Packaging)

I live near Lake Erie. At the end of the property above the lake there is a 1/3 mile long winding path from the edge of the property to the lake front along a creek. I need a bright, durable, dirt proof and water resistant flashlight because it's incredibly dark at night on the path to the lake.I've researched all brands of flashlights and have owned a wide variety of brands from the cheap 2 for $20 Amazon "specials" to $50 Mag Lights to a $100 Sure Fire flashlight. None of them have met my requirements and I've ruined all of them over time.I spent hours researching hand held lights and saw this model in one of the reviews. Here's why this particular light meets my needs:-LONG battery life on high beam, over 2 hours at 4200 lumens with the rechargeable batteries over an hour at 3200 lumens with Lithium 123 batteries. Some of the other high end lights like Olight that have 2-3 minutes on high beam with their OEM rechargeable batteries.-"Dual fuel" - this light can use four 123 lithium batteries or the OEM rechargeable batteries. The 123's aren't as bright as the OEM rechargeable batteries but they still provide excellent output while the other batteries are recharging. See the photo - the 123's are NOT included but they are readily available, cheap, last 10 years on a shelf and are excellent back up batteries-Dirt and sand proof, water resistant. I read a 1 star review whining about the lack of an external USB charging port and having to charge the batteries instead. That is actually a strong positive for me. An external USB port provides a very vulnerable entry point for dirt and water and the rubber USB port covers ALWAYS come loose and vanish. Recall that I'm using this light on a beach at night and the moisture and sand have killed many other lights in short order.-Top rate machining. This Streamlight torch is well made. The threads are precisely cut, it uses a silicone O ring on the batter cap and the switch also has a silicone cover - see the close up photos.-Three "ten tap" settings. You can change the light settings with ten button pushes to either High, Strobe, Low, High, medium and low or high only-Lower cost than most premium flashlights that allows for the purchase of 2 extra OEM rechargeable batteries that are readily available with Prime shipping that make this light the same price as many other lights with just 2 rechargeable batteriesAreas of improvement:-It could use a "lockout" button so the light cannot be accidentally activated in a back pack or day packOverall, this Streamlight model has met all my needs in tough conditions that include constant exposure to sand, dirt, moisture and water. Hope this helps!
