Ultimate Zoomie Flashlight? Speras TH4 Review
General thoughts after a week of usage/size comparison/practicality/interesting things:
• So we’re all used to multiple LED lights… nothing groundbreaking there… except, they’re often flooders or if they come with a spot beam, take up too much room due to the bulky head. Well, Speras has solved that problem in the TH4! Sure, it’s not an EDC light. It has four different colored LEDs that each can be mechanically activated with a twist of the wrist. With a nearly 800m range, it’s pretty impressive. The TH4 is marketed as a hunting light, but it can be used as a walking light or even tactical light.
Overall Construction, LED, lens, bezel and reflector
• Excellent quality construction – the TH4 looks and feels very ‘military’. Machining is on par with other high-end tactical lights that I own. There are no sharp/rough spots or inconsistencies. Anodizing is between matt black and glossy. It’s not overly grippy, and some extra knurling would have been nice. If you’re mounting this light on a rifle, this isn’t an issue. The light is operated by rotating the selector switch under the head and rotating the head itself to zoom in and out. Single tail switch that rotates to adjust brightness. Has lanyard holes and also tail stands.
• USB-C charging port on the tailswitch. The wired switch also connects here. The TH4 takes any 21700 cells. There’s a spring in the tail and head to help with recoil.
• The head has a much larger diameter than the rest of the body. Thankfully the lens is recessed. Appears to have no protective glass lens. Not sure what style of lens this is – it looks like a TIR lens with concentric rings to even out the beam. Each LED sits on a heatsink/platform that is mechanically swapped into place by twisting the switch. There’s a confident click to indicate when an LED has been swapped in.
UI – modes
• Head is rotated to zoom in and out. The selector ring beneath the head can be rotated to select G, W, R, and IR. Press the tail switch to turn on. Press and hold for longer than 0.3 seconds for momentary mode. Release to turn off. Rotating the tailswitch will increase/decrease brightness.
• USB-C wired switch. Centre button for constant on memory mode. Top button for constant on 100% – center button to turn off. When the light is on, hold to and bottom button to increase/decrease brightness.
Considerations
• Red beam is square shaped, can see bond wires – but that’s on a white wall. Outside, it’s not noticeable. I’m waiting for the day that these round LEDs will be available in different colors – that would be perfect in lights like this.
• Would like a way to LOCK the output at 100% As when I’m using the light without the wired switch, I found I rotated the dial accidentally, and was on around 80% instead of 100%. No issues with the wired switch attached, as it disables the dial when attached.
• No protective glass lens in front of the TIR lens.
• Difficult one-handed operation, but also less likelihood for accidental activation of different modes, zoom level.
• Price – you’ll pay a premium due to the mechanical LED system and 4 different beams. But there are not many alternatives out there besides the Brinyte T28 – which is missing the IR LED module, and lower range (525m)
Verdict
• The TH4 is one unique flashlight and would be useful for a hunter or perhaps someone who does night walks and would like a range of colors to choose from. The red/green LED will help preserve your night vision and is not visible to animals. Speaking of which, if you use night vision goggles, the IR LED may be useful to you to spot animals and targets from a distance without drawing attention. If you’re into throwy flashlights like I am, the TH4 is a dream as it offers a variety of throwy beams to choose from, and excellent sustained output too.
