Brinyte T28

Brinyte T28 flashlight review

Introduction:

The Brinyte T28 Artemis is a very interesting approach for a hunting flashlight, with its manual color switching and its tailcap potentiometer dimming this flashlight brings ease of use to the table so anyone can pick up this flashlight and instantly know how to operate it. It offers pure 650nm red light for night vision protection, 520nm green for the extra high contrast to see your target in the night as well as 6500k white so it can be used as a normal flashlight when needed.

What you’ll get:

The flashlight came in a plain cardboard box undamaged. The light was in a bubble wrap bag with 2 pieces of foam on either side to prevent it from rattling around in shipping and getting damaged. 

Accessories included in the box :

• Brinyte T28 Artemis
• 21700 cell with USB C port
• Remote switch tailcap for use with a hunting rifle
• 2x USB C braided cable (maybe I got two by mistake?)

Handling of the light

The T28 is a great size and fits well in the hand, the smooth anodization gives a great quality feeling when holding the light. The forward color selecting switch feels great and gives a very satisfying click when used, the back potentiometer switch has a nice and smooth action that gives a quality touch. The head isn’t so massive that it won’t fit in the pocket but it does bulge out a bit so it may be a bit uncomfortable if your wearing jeans. This light can barely perform a tail stand but it is almost too top-heavy rendering tail standing unviable. Overall the T28 is made with portability in mind so it can be used easily on a rifle or just in your hand.

Build Quality, knurling, threads, and anodization

The first thing that comes to mind when speaking of build quality on the T28 is attention to detail. The anodization is flawless as on most flashlights but this one feels different, it almost feels like it has a smoother finish than on most other lights. Both switches on the flashlight operate very smoothly and I haven’t run into any operational issues on either one. You will not find any sharp edges on the light as all parts that would be a candidate for sharpness are finished off with a nice radius. Lastly, the threads and O-rings, the threads on this light are part of the tailcap not the body tube and are squared off very precisely, and the O-rings are thick ones so you won’t have to worry about ruining a thin one by mistake.

LEDs, Lens, Bezel, and Reflector

This light uses 3 different types of LEDs, XP-E2 (Green), XP-L HI (White ~6500k) and XP-E2 (Red). Of course, as stated in the introduction these colors go hand in hand with a hunting style light and they suit the T28 well. This light is a zoomie style light which enables an infinite zoom from a very smooth and wide flood beam to a very narrow hotspot the shape of LED die for the strongest throw possible from a light this style. Contrary to what you would expect from a zoomie light this light doesn’t have an aspheric lens, to cut down the weight in a significant way they used a Fresnel lens (one could find this type of lens in lighthouses to create a strong beam). This type of lens is very thin and produces the same style of beam as an aspheric would produce albeit with a less smooth beam pattern.

Batteries and charging:

The T28 uses a 21700 cell which is provided in the package, the included battery has a built-in USB-C charging port which is helpful because most chargers can’t hold a protected 21700 cell. You can also put flat top 21700 cells in this flashlight as there are springs on the driver and tailcap, naturally, a 18650 cell can be used but a spacer is not provided.

Don’t forget to check out our page about 21700 battery chargers, to get one with longer bays.

Performance:

Amp measurement

Max brightness on each mode

• Green: .53 A
• White: .89 A
• Red: 1.01 A

Runtime graph

The T28 has a very predictable runtime which drops off very fast in the first 5 minutes (about 130 lumens) and from then on it drops at a linear rate of about 8 Lumens every 5 minutes.

Lumen measurements (for each mode)

I used a homemade lumen tube design that many people use, it is made from 3 – 3” PVC Street 90s and a cap with a hole drilled in it to hold the DR Meter LX1330B which I bought on amazon.

• White(Max): 655.75 Lumens
• Red(Max): 188.05 Lumens
• Green(Max): 157.37 Lumens

Throw numbers:

The factory claims specific throw numbers for each color,

• Green: 21,960 cd
• White: 69,600 cd
• Red: 16,480 cd

After measuring from 5m with the Dr Meter LX1330B I got a total of:

• Green: 38,349cd
• White: 86,250cd
• Red: 33,751cd

This proves the T28 provides a lot more output than the factory claims.

Rating: 4stars

I would give this flashlight a 4 out of 5, it has many interesting features that you wouldn’t find in any other flashlight but the physical part of the light could be a little better such as adding a nice knurling pattern for the handle. I could see this light being very useful for hunters because of the quick adjustments that can be made through the dimmer and the selector switch for the colors, I feel that the target audience that they want this to be portrayed to will find this flashlight very appealing and it will definitely fill a needed hole in the flashlight community.
