Nitecore EC4 Flashlight

Innovative and Powerful

The Nitecore EC4 is one of the most innovative flashlights in the world since it is the first die-cast offering in the industry. This means that it needs no separate parts welded together which ultimately results in the flashlight being more dimensionally stable, stronger, smaller and lighter. Measuring in at just under 6 inches in length, the EC4 is the perfect size to take with you when you need it most. Durability is not an issue with the EC4 as it is waterproof to IPX-8 standards and impact resistant up to 1.5 meters. Featuring a patented dual-switch system, cooling fins and rhombic knurling, this flashlight really stands out from the crowd. Its innovative construction, versatility and reliability makes the Nitecore EC4 truly one of a kind.

Lighting Technology


Equipped with a CREE XM-L2 U2 LED, the Nitecore EC4 is capable of producing an impressive 1000 lumens on turbo mode. It has 5 different brightness levels including a Turbo, High, Mid, Low and Ultra-low mode and 3 concealed special modes including a Strobe, SOS and Location Beacon mode. The EC4 runs on either 2 x 18650 batteries or 4 x CR123A batteries, which gives you more flexibility when powering your flashlight. It also features a rear thumbscrew lock that can connect to a tripod and can stand steadily on its tail. It transforms easily into a camp light or camera light when it is secured on a tripod. If you're looking for a high quality lighting experience, the Nitecore EC4 flashlight will provide you with performance like no other.

Great for wheelchair carry
August 15, 2016
The Nitecore EC4 flashlight although a bit more expensive than others that I own has really became a personal favorite for me to carry in my wheelchair side-saddle. I used to rely on the Streamlight with the tail end on/off switch. That was in the earlier days of the LED technology. It was not really bright (although bright enough) in comparison to today’s standards. My biggest issue was the tail switch getting pushed ON when I was going through a really narrow doorway. Then when I needed the light, the batteries were dead.

Although a bit larger than the tube type 18650 EDC lights that are so very popular, the design of the EC4 makes it easier to hold in my hand. The extra battery gives me a bit more confidence in case I need that extra battery life. Another plus is the beam that spreads out a little wider, lighting my travel path better than a tight beam light.

In most cases I really never need the brightest settings and mostly use the low, middle, and high settings. When the battery gets low, I can take the 18650 batteries out, recharge them and I am ready to go again. In case the batteries drain while I am not near a charger, I always carry 4 of the CR123 batteries just as a backup, although I have not had to use the backup batteries in over 6 months of ownership.
  • Really bright
  • Excellent mid-range brightness levels
  • Longer run times than single 18650 lights
  • None
Super light!!

Nitecore EC4 - just what I needed
September 9, 2016
The Nitecore EC4 is just what I've been looking for: a small, light weight, adjustable output flashlight capable of very high brightness when I need it and lower output for normal use. It feels great in the hand, the rechargeable batteries are very handy and overall it fits my needs exactly. Haven't had it long enough to judge how it holds up over time but it seems quite sturdy and well made. I have one for the house and have ordered another for my car, replacing an old Maglite there.
  • Good size, excellent choice of brightness levels, feels good in the hand.
  • None so far.

Brighter than advertised, excellent reflector, simple operations
March 26, 2016
I've owned perhaps 20 LED flashlights starting with the Inova X5. My Nitecore EC4 is consistently brighter by about 50% at the same lumen rating than other single-18650-powered lights, even with expensive Panasonic batts. I've tried to figure this out... It's probably a true 1000 lumen light, while others are substantially less (i.e. Fenix PD35, Nitecore EC20, etc). Great ergonomics, modes, etc., takes odd batts like Panasonic 18650 that won't fit in other lights due to lack of tabs. I gave away 3 other lights, even a huge 3-emitter TrustFire at 1800 lumens, after buying this. This is my #1 all time favorite flashlight. Oh and it has a very far reaching beam, tightly focused.
  • Extremely bright, maybe underrated by manufacturer?
  • Far-reaching, tight focused beam
  • Comfortable handgrip
  • Finish easily scratches (who cares)

Nice Quality Temp Compensated Light
March 23, 2016
I am pleased with the Nitecore EC4 for build quality and light output. Very bright and clear focused beam.
  • Good ergonomics for holding. Bright focused beam and ATR temperature compensation.
  • Would have liked a spare sealing ring for the screw attached base ... just in case. Tube flashlights come with a spare oring ...
