🚨 Need a duty light? The ZT40 isn't built for that — the PT16A is Brinyte's duty model (3000 lm, dedicated instant-strobe key). See FAQ below.
1. Green — Hog Hunting
If you're searching “hog hunting light green,” you've probably already read that hogs don't alarm at green. That's true, but it's not the whole reason green is the standard. The other half is human-eye physics: peak photopic sensitivity sits at 555 nm, right in the green band. A 500-lumen green beam appears dramatically brighter to you than a 500-lumen red or blue beam, which is why green scans a food plot or CRP field more effectively per lumen.
The ZT40 Green is a dedicated green LED — no filter, no phosphor conversion loss. 500 lm on flood covers a food plot; 126 m on spot (Low mode, per FL1) picks eyeshine out of the treeline. The 6°–70° rotary zoom means you don't carry a separate flooder and thrower: twist to flood for scanning, twist to spot for confirmation. IPX8 (2 m submersion), 21700 5000 mAh, hidden USB-C.
The competitor you'll see first: Sniper Hog Lights
Sniper Hog Lights is the established name in dedicated hog illumination, and the Hyperion 40 Hunters Package runs $254.00 (as of October 2026) — with a single LED module in the base price, and IR850/IR940 modules adding $20.00. It's a modular system: buy the body, buy the modules you need, swap them in the field. That modularity is genuinely useful if you run the same light across multiple species on different nights.[reference:5]
The honest trade: Sniper Hog gives you a mature module ecosystem, a larger reflector, and a stronger dealer network. The ZT40 gives you one fixed green LED, zoomable beam, IPX8, and $109.95 — no module to swap, no extra purchase to get green. If you only ever need green for hogs, the ZT40 is the cheaper, simpler path. If you want one body that swaps between five colors across a season, Sniper Hog's ecosystem is the more flexible investment.
🟢 ZT40 Green — Hog & Predator Scanning
What green actually buys you: the brightest perceived beam per lumen, a wavelength hogs tolerate at scanning distance, and a beam that cuts grass and fog better than red. The limit: green doesn't help you approach — that's red's job. If you're closing distance on a pressured sounder near a feeder, switch to a red version or use the tri-color T28 Artemis.

2. IR850 vs IR940 — Night Vision
This is the decision nobody structures properly. If you already own a digital night vision device (ATN X-Sight, Pulsar Digex, etc.), the IR wavelength you choose determines both how far you can see and whether the animal notices you at all.
| Wavelength | Effective range (digital NV) | Visibility to game | Best for |
|---|---|---|---|
| IR850 | ~250–350 yd | Faint red glow visible at close range; boar/deer can detect it if pointed at their eyes within ~50 m | Maximum reach; open fields where distance matters more than absolute stealth |
| IR940 | ~150–250 yd | Completely covert to game at any practical hunting range | Wary, pressured animals; close-to-mid range where stealth is the priority |
The rule of thumb: 850 for reach, 940 for stealth. If your hogs are unpressured and you're scanning open ground at 300 yards, 850 gives you the brightness. If they've been shot at before and you're working thick cover inside 200 yards, 940's total covertness is worth the lost reach.
The competitor you'll see first: Nitecore CI7
The Nitecore CI7 is the most direct “white + IR in one body” competitor: 2500 lm white plus a dedicated 940 nm IR array, around $129 (as of October 2026), IP68. It's a genuinely good light, and the dual-emitter design means you get white and IR without swapping anything.
The honest trade: the CI7 is brighter on white (2500 lm vs 1650 lm) and gives you white + IR in one body — but it only offers 940 nm, not 850. If your NV device performs better at 850, or you want the option to swap between 850 and 940 based on conditions, the ZT40 IR is the more flexible choice. If you want one light that does white and covert IR with no swaps, the CI7 is the stronger single-body answer.
🌙 ZT40 IR850 / IR940
Choose IR850 if your digital NV needs maximum illumination distance and your animals aren't heavily pressured. Choose IR940 if total covertness matters more than reach — pressured hogs, close-range timber, or any situation where a faint red glow at 50 m could spook the group.
3. Red — Deer & Coyote
Deer are dichromats — they lack the cone type that detects long wavelengths, which is why red light appears as dim gray rather than a distinct threat. That's the science behind every “do deer see red light” answer: red doesn't make you invisible, but it's the least alarming visible wavelength at close range. It also preserves your own night adaptation, which matters on a 20-minute walk-in.
The ZT40 Red delivers 450 lm / 273 m spot — enough to pick eyeshine out of a field edge, not so much that it floods the approach with light. The zoom lets you widen to flood for the walk-in and tighten to spot for the final identification. Same IPX8, same 21700, same 6°–70° mechanism as every other ZT40 version.
The competitor you'll see first: Primos Bloodhunter HD
Primos is the most-cited name in red hunting lights, and the Bloodhunter HD (around $70, as of October 2026) is a single-purpose red/white tool designed primarily for blood tracking. It's cheaper than the ZT40 Red and does its specific job well.
The honest trade: Primos is a dedicated blood-tracking light with a narrower beam and less throw. The ZT40 Red gives you 273 m of zoomable throw, IPX8 submersion, and the same 21700 platform as your other ZT40 versions — which matters if you want one battery ecosystem across deer, hogs, and NV. If red is only for tracking and you don't need throw, Primos is the cheaper tool. If red is your deer-approach color and you want it to double as a scanning light, the ZT40 is the more versatile body.
🔴 ZT40 Red — Deer Approach & Coyote
Red is a close-range tool. It preserves night vision and won't flag deer at 30–80 yards, but it's not a scanning wavelength — green covers that job better. If you hunt deer and hogs on the same property, carry both, or use a tri-color headlamp for hands-free switching.
4. White — Hiking, Search-Rescue & Long-Range Outdoor Use
The white ZT40 is a different interface from the hunting versions, and that difference is deliberate. It runs a forward-clicky tail switch with two modes only — momentary and constant-on, High and Low. No mode cycling, no memory, no accidental strobe when you're under stress. That's an outdoor interface, not a duty interface.
1650 lm / 490 m / 60,000 cd on High, 500 lm / 3h 45m on Low. IPX8 to 2 m. The 6°–70° zoom goes from camp-flood to a 490 m spot for scanning a ridge line or a shoreline. This is the version that fits a hiking pack or a SAR rucksack — and the same body, battery, and charger as your hunting ZT40.
The competitor you'll see first: Fenix HT18R V2.0
The Fenix HT18R V2.0 is the default professional long-range outdoor answer at $149.95 (as of October 2026) — 3700 lm, 1100 m, 6000 mAh 21700, IP68, lifetime warranty, a mature dealer network. It outperforms the ZT40 white on raw output and throw, and it's the safer buy if brand support and maximum reach are your priorities.
The honest trade: Fenix wins on absolute performance and warranty depth. The ZT40 white wins on zoom versatility (the HT18R is fixed-beam) and platform economy — if you already own a hunting ZT40, the white version shares batteries, charger, and muscle memory. If your job is long-range outdoor scanning and you need one light that does everything, the Fenix is the stronger single-purpose tool. If you want a white outdoor light that lives in the same ecosystem as your hunting lights, the ZT40 is the practical choice.
⚪ ZT40 White — Outdoor / SAR
5. UV — Fluid Detection (Honest Caveat)
The UV ZT40 (365 nm, 145 lm) is the version that needs the most honest framing. UV does make certain biological fluids fluoresce, and it's a legitimate tool for forensic and some tracking scenarios. But on dried blood, green light is generally the stronger choice — hemoglobin absorbs green wavelengths (peak around 540 nm), creating high contrast against leaves and dirt. UV's advantage is fluorescence on fresh, specific fluids; it's not a universal “blood tracker.”
If blood tracking is your primary mission, a dedicated strobe-based light (like the T5X SPECTRA's 10 Hz/5 Hz temporal contrast) or a high-CRI green will outperform UV in most field conditions. Buy the UV version if you have a specific forensic or fluid-detection use case — not because “UV finds blood” sounds good on a spec sheet.

6. Six Versions, One Platform — What Actually Changes
Every ZT40 shares the same body, the same 6°–70° zoom, the same IPX8 sealing, and the same 21700 5000 mAh USB-C battery. What changes is the LED and the interface — and those changes are matched to a mission, not a marketing tier.
| Version | Output / Throw | Interface | Mission | Price |
|---|---|---|---|---|
| White | 1650 lm / 490 m / 60,000 cd | Forward-clicky, 2 modes, no strobe | Hiking, SAR, long-range outdoor | $109.95 |
| Green | 500 lm / 126 m spot (Low) / 70 m flood | Rotary zoom, tail switch | Hog scanning, predator | $109.95 |
| Red | 450 lm / 273 m spot | Rotary zoom, tail switch | Deer approach, coyote | $109.95 |
| IR850 | 100 lm / 50 m | Rotary zoom, tail switch | NV, max reach | $109.95 |
| IR940 | 100 lm / 50 m | Rotary zoom, tail switch | NV, max stealth | $109.95 |
| UV 365 | 145 lm / 230 m | Rotary zoom, tail switch | Fluid detection, forensic | $109.95 |
Buy the version that matches the wavelength your game can't see — green for hogs, red for deer, IR for NV, white for hiking and SAR. Then add a second version later if your season spans more than one mission. The battery, charger, and zoom muscle memory transfer. That's the entire argument: not one compromised light, but a platform where each version is honest about the one job it does.
7. Frequently Asked Questions
What color light is best for hog hunting — green or red?
Green for scanning, red for approach. Green appears brightest per lumen to the human eye and hogs tolerate it at distance, which makes it the better scanning wavelength. Red is less alarming at close range and preserves your night vision, which makes it the better approach color. If you can only buy one, green covers more hog-hunting situations. If you can buy two, green + red is the complete pair.
850nm or 940nm for hog hunting with night vision?
850 nm for reach, 940 nm for stealth. IR850 throws farther (~250–350 yd effective with digital NV) but produces a faint red glow that pressured boar and deer can detect if you point it at their eyes within ~50 m. IR940 is completely covert at practical hunting ranges but reaches less far (~150–250 yd). If your animals are unpressured and distance matters, 850. If they're wary and you're working close cover, 940.
Do deer see red light?
Deer are dichromats — they lack the cone type that detects long wavelengths. Red light doesn't make you invisible, but it appears as dim gray rather than a distinct threat, which is why it's the standard for close-range deer approaches. It also preserves your own night vision for the walk-in. White light is the wavelength that flags deer most reliably.
Is green light better than red for hogs?
Green is better for scanning — it appears brighter to the human eye per lumen, cuts grass and fog, and hogs tolerate it at distance. Red is better for closing distance on a pressured sounder near a feeder. The two wavelengths do different jobs; “better” depends on whether you're scanning a field or approaching a group.
Best zoomable hunting light for hogs?
If you want a single fixed green LED with zoom, IPX8, and a 21700 battery, the ZT40 Green ($109.95) is the simplest answer. If you want green + red + white in one body with instant switching, the T28 Artemis ($119.95) covers all three. The ZT40 wins on single-wavelength purity and zoom simplicity; the T28 wins on multi-color versatility without swapping.
Is the ZT40 IR compatible with digital night vision?
Yes — both IR850 and IR940 work with digital night vision devices, which typically accept 850–980 nm. Analog Gen 3 tubes also work, with IR850 generally producing a brighter image. Confirm your specific device's IR sensitivity range before buying.
Red or green for coyote hunting?
Red for coyote. Coyotes are more observant than hogs and are more likely to flag on green at close range. Red preserves your night vision and is the less alarming wavelength for a close approach. Green is a better scanning color if you're trying to pick eyeshine out of a field at distance, but red is the approach color.
Can the ZT40 be used as a police duty flashlight?
No — it isn't designed for that, and forcing it into a duty role would be the wrong tool. The ZT40's two-mode interface (momentary / constant-on, High / Low) was built for hunting, hiking, and search-rescue use. It has no strobe, no SOS, and no duty-oriented control layout. Those omissions are deliberate: the ZT40 is a zoomable outdoor light, and it's better at that job for not trying to be everything.
If you arrived here looking for a police or security duty light, the right Brinyte product is the PT16A — 3000 lm, 52,500 cd / 458 m, IP68, dual tail switches, and a dedicated instant-strobe key that fires from any mode without cycling. It's the model Brinyte positions for duty use. For the full duty-light lineup, see our tactical light guide.
