How your new EA45S works.
The brightest and longest reaching AA battery powered light in Nitecore's range.
When you can only use AA batteries and still need the brightness and reach of a modern tactical light, this is the one to go for.
- 1000 lumen brightness over 402 meters
- 45min runtime on 1000 lumens
- Full aluminum unibody design for maximum strength
- Uses just 4 AA batteries for maximum compatibility
- Slim ergonomic shape for comfort and grip
- Easy 2 button control with 5 brightness levels
- IPX8 waterproof fown to 2m, 1.5m drop resistant


The most powerful AA battery light in Nitecore's arsenal. Incredible strength and heat managment with advanced unibody design.
SUPER STRONG UNIBODY DESIGN - Milled out of a solid piece of aluminum with cooling fins, this gives you amazing strength and heat dissipation for a lifetime of use.
4x AA BATTERY COMPATIBILITY - Perfect for overseas work where USB recharge ports are not readily available but AA batteries are easy to find.
BLINDING 1000 LUMEN BEAM - Typical AA lights cap out at around 345 lumens, this pushes it all the way to 1000 lumens with 4 batteries.
EASY 2 BUTTON CONTROLS - One for on/off, and one for switching between brightness levels. Get instant access to turbo or ultra low when the light is off by holding either buttons as well. A power indicator built into the on/off switch indicates remaining battery power.
ERGOMONIC SHAPE - Body shape has built in water and sweat flow channels for efficient gripping. Its oval shape is designed to fit your palm perfectly.
READY FOR ANYTHING - Waterproof and sealed down to 2m, the EA45S can take on any climate. Advanced Temperature Regulation (ATR) technology ensures optimal performance based on the environment's temperatures.


The problem some clients face is lack of recharge points at the country or place they're going to.
And they can't bring a high powered, rechargable light along because they won't be able to charge it anyway.
That's when they have to rely on AA batteries because they can be found and bought pretty much anywhere in the world. Even in disaster situations, you can find AA batteries by going into homes and looking behind wall clocks, remote controls and kids toys.
You can't go into a convenience store and ask for a pre-charged 5000mAh 21700 batteries.
This is where the EA45S comes in. It runs on 4x AA batteries and does 1000 lumens, on par with today's tactical lights like the MH12 & P20i. Of course you won't get the runtime of the modern batteries but you get compatibility.
And the beam distance at 400m is no slouch either. Hitting further than most modern lights because of the deep reflector design.
If AA battery combined with brightness and distance is your priority, then there's no other light than the EA45S.
