ThruNite TN30 Review
Pros:Outputs a huge amount of light. Simple and intuitive user interface.
Cons:Struggles to maintain regulation and gets quite hot at its highest output level.

Alongside the TN31, ThruNite has also released the TN30. Unlike the TN31 which is designed to be a thrower, the TN31 aims to provide a wider beam more suited for general use. Up the front is a stainless steel bezel with some shallow crenelations. Due to the size of the head, these are obviously not meant to be used as a blunt tactical weapon, but rather just to allow light to shine through when the ThruNite TN30 has been left switched on and placed head-down. The bezel can be easily removed by simply unscrewing the it from the head if you ever need to change the lens. You can’t use the TN31 without the bezel though, because it keeps the lens in place. The ultra-clear tempered glass lens is really nicely made, its anti-reflective (AR) coating makes the lens look so clear, you might think it wasn’t even there. This should really help with optimum output as it minimizes reflected light and maximizes light output through the lens. A large, triple-cup reflector in housed within the head for each of the 3 XM-L LEDs. Its surface is clean and well-polished with no noticeable flaws. There are some subtle circular radiating machining lines running down the reflector, but these are really unnoticeable unless you really look for it. Each fo the 3 XM-L LEDs are aligned nicely to their respective reflector cups. Externally, the head has a clean conical design with a few shallow cooling fins. A magnetic mode selection ring is placed towards the rear of the head, this controls all output modes available with the TN31. This mechanical ring has a really smooth feel when rotated and still provides tactile detents at each position of the corresponding output modes. These detents are also nicely spaced so you’re unlikely to accidentally rotate past the mode you want. One shortfall I’ve noticed is that there are no specific markings for each of the 6 constant illumination output modes the TN30 provides.
The threads between the head and battery tube are cleanly cut and mate well with each other. They also came nicely lubricated which is nice. There’s a rubber o-ring just behind the threads on the battery tube which provides a moisture seal from the elements. The entire battery tube is pretty simple and clean looking, keeping to the traditional cylindrical form factor with a generous amount of textured knurling all around. The entire body of the TN30 is finished in black Type III anodizing, as are the threads too which allows the TN30 to be locked out by simply loosening the head. The TN30 comes with a battery magazine which holds 3x 18650 batteries. The battery magazine is well-made and sturdy, it holds the batteries in place well with no complaints. Inside the battery tube, a couple of contact springs are placed at the rear end which provide electrical contact and also helps reduce battery rattle. The TN30 has a reverse-polarity protection feature built-in for safety as well. The tail cap is permanently adhered to the battery tube and is not meant to be removed. The switch used in the TN30 is of the forward push button variety which allows the TN30 to be momentarily activated by half-pressing the switch while not affective the mode selection which is completely controlled by the control ring on the head. The switching mechanism has a slightly longer than average travel, with average resistance and provides a positive tactile feel and audible click when engaged. The rubber push button switch cap is small compared to the diameter of the battery tube, however is still easy to use and activate. The switch cap sits recessed within the tail end which allows the TN30 t tail stand without problems. There are also a couple of holes at the rear end for lanyard attachments.
The ThruNite TN30 provides 6 constant illumination output levels and tactical strobe. There are accessible by rotating the magnetic control ring clock-wise (with the head facing forward) in the following order.
Level 1 > Level 2 > Level 3 > Level 4 > Level 5 > Level 6 >Stand By > Strobe
ThruNite has considerately included the Stand By position of the control ring as it allows the TN30 to be switched off without needing to reposition your hand to click the switch. The range of output provided by the TN30 is really wide, ranging from <1 to 809 lumens (tested). This range should cover all but the most demanding of use case scenarios. Even though the TM30 has a triple LED setup, their beams converge well and the resultant hot spot looks circular, practically indeclinable from a single LED flashlight. The hot spot itself is actually narrow, almost as narrow as that of the TN31, however there’s a bright corona surrounding the hot spot which makes the hot spot area seem wider. The spill beam on the other hand, does give away the TN30′s triple reflector design as the spill beam produced is petal-shaped with some overlapping regions. Overall the beam profile is clean with no noticeable flaws. One area where the TN30 falls short is in terms of regulation. While the TN31 holds stable regulation for the most part, the TN30 takes a steady dimming of output especially noticeable on the brightest Level 6 output mode. To be fair, the TN30 does output an excess of 2000 lumens on Level 6, many flashlights would have a similarly difficult time trying to maintain perfect regulation at such levels. Also, the TN30 seems to intermittently dim when going from Level 5 to Level 6, but this doesn’t effect practical use since the dimming only lasts about half a second. As a side note, the TN31′s electronics come with a temperature control feature which protects the light from excessive heat. This essentially means that depending on the environment in which you use the TN30, it might ramp down output if there is insufficient cooling ability.
