Nitecore SRT7 Flashlight Review

The Birth Of Nitecore

Nitecore, the brainchild of Edgetac Pty Ltd, was created in 2007. Edgetac Pty Ltd. was a large OEM/ODM manufacturer with extensive experience in the conception, engineering and manufacturing of portable lighting products. Continuing to design and manufacturer personal lighting products under numerous brands, both in China and through the U.S. and Europe, to this day.

Edgetac’s bold decision to branch off from the mainstay of their business and develop the Nitecore brand was largely due to identifying a market niche for small, precision-made ultra-high output multimode torches. Nitecore’s origins are highly unusual, born out of forging alliances with several small niche manufacturers and drawing inspiration from the vast collective of knowledge that exists within online hobby groups and enthusiast forums the world over. This unconventional business model has seen the brand go from strength to strength in the short time since its inception.

The Nitecore SRT7 is a medium sized flashlight. It features the latest technology, the third generation SSR or “Smart Selector Ring” and is part of the Smart Ring Tactical Series, which includes a total of 4 flashlights. As the name suggests, it is primarily marketed toward law enforcement, military as well as hunters. I believe the Nitecore SRT7 is the first of its kind to offer a set of three RGB LEDs inside the primary emitter to produce a variety of colored outputs.

The total length is 6.22” with a 1” barrel and 1.57” width at the head. Without batteries the SRT7 weighs 6.1 oz. The main barrel is constructed of aircraft grade aluminum that has been anodized, giving it a tough exterior.

The typical tail switch like other tac lights is covered with a rubber boot. At the business end of the light is a toughened, mineral glass with an antiglare coating. The bezel is made from stainless steel which protects the lens and smooth reflector inside.

The Nitecore SRT7 Revenger Flashlight has IPX-8 rating for submersion of up to 2 meters and impact resistance of up to 1.5 meters. to help improve the shock resistance, Nitecore uses a spring inside the barrel to help with absorbing the impact when dropped. Also great for gun mounts so when the gun recoils, you still get a consistent light source without a flicker. One thing to note is that the head spring contact is recessed so it does not make contact with flat topped batteries. I suggest using the Nitecore 18650 batteries with this light.

This light has a very effective outer surface because of the knurling along with the deep slots around the entire diameter. This makes for a great grip and easy disassembly. It does come with a cigar style grip that fits directly between the main barrel and tail cap, if screwed off.  The tail cap is protected by to raised edges that each have a hole in them for a lanyard attachment. Also this raise portion around the tail cap makes for a flat surface and the light can stand on end.

The Nitecore SRT7 boasts the very latest CREE XM-L2 T6, configured for a maximum output of 960 lumens. While there are three secondary RGB LED’s built inside the reflector wall, the real action is in the main LED. Powered by either 2 CR123’s, RCR123’s or my favorite 18650 rechargeable batteries. Now the maximum runtime on the lowest lumen of .1 is 200 hours and the highest lumen is 1.45 hours. You can purchase EagleTac 3400mAh rechargeable 18650 batteries which should yield longer runtimes.

1-1_SRT7_En9_1024x1024The user interface consists of a tailcap switch and the Smart Selector Ring. All the modes can be momentarily accessed by partially depressing the forward clicky tail switch. For the constant on position just fully press the tail switch. One concern I had with this light was the accidental mode changes. However, all the modes are separated by the noticeable detent.

The very first mode is the standby mode. When the light is powered, a small red LED on the side of the head blinks every two seconds to indicate the light is on. This is a great energy saving feature that most others don’t incorporate into their designs. When the light is low on battery juice the LED flashes quickly. Next we have the variable brightness mode. This is a the smooth ramping power of the CREE LED from .1 lumens all the way to 960 lumens. One more detent over is the high frequency strobe . This is a great place for it because law enforcement professionals can set this easily without a hassle. If you turn the SSR counter clockwise from the standby mode, it will cycle through the Red, green and blue LEDs. One more detent is the flashing red and blue police like mode. Finally, the furthest click over is the beacon that flashes at slow intervals but on the highest brightness.

1-1_SRT7_En_1024x1024Like a MAC, the Nitecore SRT7 interface is intuitive despite the number modes it has. With the exception of the SSR which is the wide smooth area of operation, it is just a few single clicks from one mode to the next.

As for the output, the primary beam is bright and has a fairly focused hot spot with a large spill area. I think the RGB LED pockets contribute to the blending from the hot spot to the spill and actually plays to my advantage as a user. Some lights that reach 336 yards like this does, tend to have a more harsh difference between the hot spot and the spill. I prefer to use this type of beam for the majority of outdoor use.

The least impressive aspect of this light is the RGB LEDs. The brightness is low on all of them and is probably only suited for close up jobs like reading a map, compass. I would note the green and red are enough light to maintain night vision. These RGB LEDs are in a distinct format and cast three distinct triangular shapes when turned on. If you would like to have a brighter red, green or blue light, Nitecore makes a diffuser that fits the bezel.

1-1_SRT7_En6_1024x1024Lastly is the carry options the Nitecore SRT7 has. It comes with a well made, nylon sheath that holds the light with the bezel side up. It uses a velcro flap to hold the light in place and has the bottom cut out for even more security. On the backside of the holster is a the standard D ring, which in this case is metal and a velcro belt loop for easy attachment. Nitecore also includes the lanyard, O rings, and spare tail cap switch boots.

Best Flashlight Spot:

Overall the Nitecore SRT7 Revenger is a comprehensive flashlight. The primary emitter is super bright and versatile due to the “infinitely variable” control. Unlike many other lights of this size, the Nitecore SRT7 is a rechargeable style flashlight. I also like the fact the beacon and strobe has limits, allowing for a quick, no fuss access when needed. While the RGB LED’s are lacking. Regardless of the quirks, the SRT7 is a great buy for anyone looking for a work light. It’s well machined and built to last.
