Nitecore SRT7GT LED Flashlight

Multi-Color Tactical Light

From police officers, to hunters, to first responders, the Nitecore SRT7GT LED Flashlight is the perfect light for all tactical users. Powered by a single 18650 battery or a pair of CR123A batteries, this potent torch is capable of producing 1000 Lumens of radiant white light thanks to its sophisticated CREE XP-L HI V3 LED. The SRT7GT features a smooth aluminum reflector, which combined with the light's Crystal Coating Technology allows its beam to throw nearly 1500 feet away; that's nearly 5 football fields! In addition to its CREE LED, this versatile light sports 4 secondary colored LEDs (Red, Blue, Green, and Ultraviolet) that can be used for a number of tactical purposes. The Red LED helps preserve a person's natural night vision, perfect for a variety of nighttime activities. The Blue and Green LEDs are ideal for hunters and sportsmen, while the Ultraviolet LED can be useful for everything from police work to currency inspection.

Smart Ring Technology

The SRT7GT is operated using a rubber tailcap switch and Nitecore's patented Smart Selector Ring, a one-of-a-kind operating system that allows for optimal functionality and customization. The dial-like switch rotates around the light's body allowing for seamless switching between different outputs, including a tactical strobe, a location beacon, and a special blue and red police warning flash. The selector ring also provides adjustable brightness for its main CREE LED, allowing for free adjustment anywhere between 0.1 and 1000 Lumens. Thanks to its incredible versatility, the SRT7GT is able to provide lighting for just about any situation.

Built to Last

The SRT7GT is as durable as it is versatile, constructed from aerospace grade aluminum alloy and coated with a military grade hard-anodized finish. The light's LED and other internal components are protected by a optics glass lens with anti-reflective coating and is sealed tight by a stainless steel bezel. The rugged body gives the SRT7GT incredible resistance to impacts, protected from drops as high as 1.5 meters (4.9 feet), as well as water damage, earning an IPX-8 rating in water resistance. The flashlight is even protected internally, utilizing a spring-loaded absorption mechanism that provides reverse polarity protection.

Make it Rechargeable!

The Nitecore SRT7GT tactical flashlight is now available as an all-in-one bundle, pairing the handheld light with a rechargeable 18650 battery, which is equipped with a built-in charge port. Also included in the bundle is a micro USB cable. No more having to buy a bulky battery charger! Both of these accessories purchased together typically retails for around $23.50. Now you can add on both to your light for just under $12. That's a $12 savings!

Love this light
By Eric
Great multipurpose light
October 19, 2018
Search & Rescue missions its one of my regulars in the arsenal due to the options.

My buddy who is a marine just got one too after he saw mine in the field.

Actual white light is bright hot spot and good thrower for its size - not a ton of spill but good for most applications.

Dial is nice once you remember which way to turn the dial. Prefer not to have strobe at far end of max power though. And a separate rapid deployment button as needed.

Well made multiple uses and really a solid light to add to the collection!

UV, blue, red, green lights are great just a little more power would be nice

Red Blue alternating light wish they were more powerful for application in LE use

I'm using 18650 batteries and this light is awesome, always ready and with the smart ring I can dial in the light needed for the job at hand. super easy to use and perfect pocket carry.
ProsEasy to use always the right amount of light for the job

Nitecore makes a great light. I have a few and have never had a issue with any of them. The SRT7 throws quite well and I love the functionality of the smart ring so much that I'm thinking about purchasing the SRT9 as well.
ProsUnless your putting it on a weapon, the smart ring function far surpasses any button system I have used. And like all Nitecore products comes with an extra O-ring and a quality case or holster for the light.
ConsNone yet.

Nitecore nailed it!

I've been carrying this light for about a month now. This is the most versatile large 2 CR123 - 18650 light I have.
The infinitely adjustable main beam along with the 4 colored LED's allows this light to do anything I need it to.

As another reviewer said, while it does come with pocket clip, the 1.5" head really does make it too big for a pocket.
I carry mine in a Maxpedition 5" flashlight sheath.

All of the colored secondary LED's output many more lumens than listed in the packaging. With their placement in the reflector, the each have their own hotspot.

The only thing I would change is the Red/Blue strobe. I really don't see any use for it, and I think Nitecore should make this an SOS setting or eliminate it entirely.
ProsCR123 & 18650 Usable UV Infinitely adjustable main LED Tail Stand Lock out "Standby" setting Throw
ConsRed & Blue Strobe. I don't think this would be used by LEO's and for the rest of us, it can get you in trouble.
