Review on 🔦 UltraFire Mini Flashlights - 3 Pack of SK68 Single Mode Tactical LED Flashlights - Focus Adjustable, Ultra Bright 300 Lumens Torch by Andrew Kay

First off, this is a very bright little single mode flashlight that runs on just 1 AA battery. So don't expect it to last 30 hours. I bought 6 of these (all worked right out of the box) and tested the battery life with 5 different batteries (done 2 tests for each battery). Here are my results: 1) Sunbeam Super Heavy Duty Non-Alkaline (Dollar Store): 3 hours 2) Walgreen Alkaline Water: 1:523) Duracell: 4 hours 4) Energizer max: 3:225) Energizer Lithium Ultimate: 6: 43 small rehearsals but I think that should at least give you an idea of how long they should be. Lithium batteries are extremely expensive but can be useful for emergencies, e.g. B. as an emergency set (also have a much longer shelf life). Otherwise I would probably use Duracell. Finally, I would definitely avoid the Walgreens brand. They're over 6 times the price of the junk shop and didn't even last that long. I definitely recommend these wonderful little flashlights. They're inexpensive, durable, and very bright. Hope this helps.
