Olight Perun 3 Review: Key Features and Specifications
The Nitecore HC75 UHE is a high-performance rechargeable headlamp built for those who need serious brightness in a wearable form. Priced at $99.95, it is the most premium headlamp in our test group. It claims a maximum output of 3,000 lumens and a 209-yard beam throw, with an E-focus system that lets you zoom from a wide floodlight to a precise spotlight depending on the task. It also claims to be fully waterproof and drop resistant. This versatile headlamp excels across outdoor activities, demanding work environments, and emergency situations. With a built-in rechargeable battery and multiple lighting modes, it’s designed to deliver reliable performance wherever you need it most.
Key Features
3,000-Lumen Output with 192-Meter Beam Throw
The Nitecore HC75 UHE doesn’t hold back on brightness. Driven by 8 quad-core UHE LEDs in a matrix layout, it fires out 3,000 lumens with a reach of up to 192 meters which is more than enough to cut through complete darkness on job sites, trails, or anywhere you need serious light coverage.
Patented E-Focus Beam Adjustment
Forget mechanical zoom levers. The HC75 UHE uses an electronic focus system that lets you smoothly shift between a wide floodlight and a tight spotlight with a button press. Three quick-access beam presets — Mixed Light, Floodlight, and Spotlight — are also built in for when you need to switch fast.
4,500K Neutral White Light Mode
The HC75 UHE uses a 4,500K neutral white color temperature, which sits closer to natural daylight than the harsh cool-white light found on most headlamps. The result is softer, more comfortable illumination that’s easier on the eyes during long work sessions or extended time outdoors.
Up to 84 Hours of Runtime
Equipped with a high-capacity 5,500mAh 21700 Li-ion battery, the HC75 UHE can stretch its battery life up to 84 hours on its lowest setting. Five brightness levels give you full control over how you balance output and runtime depending on the situation.
Fast 18W USB-C Charging Port
The HC75 UHE charges quickly through a built-in waterproof USB-C port, reaching a full charge in roughly 2 hours and 10 minutes at up to 18W. A 4-stage LED indicator on the front keeps you updated on battery levels so you always know where you stand.
IP68 Waterproof & 2-Meter Impact Resistance
Built from aerospace-grade aluminum alloy with a military-grade HAIII hard-anodized coating, the HC75 UHE is rated IP68 and can be submerged up to 2 meters. It also handles drops from up to 2 meters, making it a genuinely rugged tool for harsh conditions.
Advanced Temperature Regulation (ATR)
Running at full brightness for extended periods generates heat, and the HC75 UHE handles that automatically. Its built-in ATR module monitors operating conditions and adjusts output as needed to prevent overheating — keeping performance stable and the headlamp safe during heavy use.
Dual-Button Interface with Lockout Mode
The two buttons on top are shaped differently so you can tell them apart by touch alone, even in the dark or with gloves on. A lockout mode is also included, letting you disable the headlamp during storage or transport to avoid accidental activation.
Emergency & Night Vision Modes
When the situation calls for it, the HC75 UHE has SOS, Beacon, and Red Flashing modes ready to go. Two red light settings are also available for situations where preserving night vision matters or when you’d rather not attract insects during nighttime use.
Lightweight & Comfort-Focused Design
Despite its output, the Nitecore HC75 UHE weighs just 209g with the battery installed. A near-center-of-gravity bracket spreads the weight more evenly across the head, while a padded rear cushion reduces forehead pressure, making it comfortable to wear for hours at a stretch.

How We Tested the Nitecore HC75 UHE Rechargeable Headlamp
Test 1: Comfort Test
We put the Nitecore HC75 UHE on to check how the headband fits, how it feels in terms of weight, and whether it stays secure when you move around.
Test 2: Brightness Test
Using a lux meter app positioned one foot away from a wall, we measured the actual light output of the Nitecore HC75 UHE at its highest setting.
Test 3: Real-World Night Visibility
We took the Nitecore HC75 UHE outside at night to see how well it actually illuminates the surroundings in a real environment.
Test 4: Waterproof & Water Resistance Test
Nitecore rates the HC75 UHE at IPX7, which means it should be able to handle full submersion in water. We tested that claim by submerging the unit underwater for 15 seconds, then checked whether it still worked normally afterward.
Test 5: Drop Test
Nitecore says the HC75 UHE is impact resistant, so we dropped it from waist height onto a hard surface to see if it held up then checked for any damage and confirmed it still functioned.
Test 6: Battery Runtime Test
We ran the Nitecore HC75 UHE at full brightness and let it go until the battery was completely drained to find out how long it truly lasts.

Bottom Line: The Nitecore HC75 UHE delivers impressive real-world night visibility. The wide, powerful beam does an excellent job of lighting up large outdoor spaces, making it easy to see everything around you without straining your eyes.
Test 4: Waterproof & Water Resistance Test
Setup: Nitecore rates the HC75 UHE at IP68, meaning it’s designed to handle full submersion in water. We put that claim to the test by submerging the unit completely underwater for 15 seconds, then checked whether it still functioned normally afterward.
Observation: The HC75 UHE passed without any issues. After being fully submerged for 15 seconds, it turned on and functioned exactly as it did before the test.
Bottom Line: The Nitecore HC75 UHE lives up to its IP68 waterproof rating. Whether you’re caught in heavy rain or working in wet conditions, you can count on this headlamp to keep going.
Test 5: Drop Test
Setup: Nitecore claims the HC75 UHE is impact resistant, so we dropped it from waist height onto a hard surface to see if it could handle the impact. After the drop, we checked for any visible damage and tested whether it still worked properly.
Observation: The HC75 UHE came out of the drop without a scratch. After hitting the hard surface, we picked it up, powered it on, and it functioned exactly as it did before without issues.
Bottom Line: The Nitecore HC75 UHE holds up well under impact. A waist-height drop onto a hard surface was no match for its rugged build, giving you confidence that it can handle the occasional accidental drop in the field.
Test 6: Battery Runtime Test
Setup: We set the Nitecore HC75 UHE to its maximum brightness and let it run continuously until the battery was completely drained to find out how long it actually lasts in real-world use.
Observation: The Nitecore HC75 UHE ran for 1 hour and 42 minutes at full brightness before the battery finally gave out.
Bottom Line: At maximum brightness, the Nitecore HC75 UHE delivered 1 hour and 42 minutes of runtime which is a respectable result for a headlamp pushing this level of output.

vs. Olight Perun 3 Rechargeable Headlamp
This is the closest matchup in the group. Both headlamps deliver 3,000 lumens of max output, carry an IP68 waterproof rating, and run on large-capacity 21700 batteries. The Nitecore pulls ahead in beam distance at 630 feet versus the Olight’s 524 feet, has a larger 5,500 mAh battery, offers 120-degree tilt adjustment, charges via USB-C, and delivered a longer runtime of 1 hour and 42 minutes at full brightness compared to the Olight’s 1 hour and 12 minutes. The Nitecore also recorded a higher lux reading of 10,155 versus the Olight’s 8,252 in our real-world brightness test. The Olight counters with its 2-in-1 headlamp and handheld flashlight design, a proximity sensor, magnetic mounting base, and a lighter build at 5.29 oz versus the Nitecore’s 7.37 oz. Both are high-performance headlamps — the Nitecore wins on raw output, range, and runtime while the Olight wins on versatility and portability. Read our full Olight Perun 3 review to see how it performed in our hands-on tests.
vs. Nebo Transcend 1500 Rechargeable Headlamp
The Nebo Transcend 1500 is a capable mid-range headlamp, but the Nitecore HC75 UHE outperforms it in nearly every measurable category. The Nitecore doubles the Transcend’s max output with 3,000 lumens versus 1,500 lumens, reaches further at 630 feet versus 423 feet, and offers a significantly longer runtime of 84 hours on low compared to the Transcend’s 28 hours. Both carry strong waterproof ratings — the Nitecore at IP68 and the Transcend at IPX7 — but the Nitecore’s rating is more comprehensive. Where the Transcend fights back is in weight at 4.9 oz versus the Nitecore’s 7.37 oz, and its USB-C charging is more universally convenient. For serious output, long runtime, and rugged durability, the Nitecore HC75 UHE is the stronger headlamp. For a lighter, more compact option at a lower price point, the Transcend 1500 holds its own. Read our full Nebo Transcend 1500 review to see how it performed in our hands-on tests.
vs. Danforce Bold-S LED Headlamp
The Danforce Bold-S surprises with its 800-foot beam distance — the longest throw in this entire group, edging out even the Nitecore’s impressive 630 feet. However, the Bold-S tops out at just 1,080 lumens compared to the Nitecore’s 3,000 lumens, carries only a vague “water resistant” rating with no official IP certification, and is the heaviest headlamp in the group at 10.6 oz — noticeably heavier than the Nitecore’s already substantial 7.37 oz. The Nitecore also offers far more versatile lighting with its E-focus beam adjustment, red light modes, SOS, and Beacon signaling. For raw beam distance, the Bold-S has a surprising edge. For everything else — brightness, waterproofing, runtime, and versatility — the Nitecore HC75 UHE is the clear winner. Read our full Danforce Bold-S review to see how it performed in our hands-on tests.
vs. BIAT Wide Beam Headlamp
The BIAT comes as a 2-pack and is one of the more budget-friendly options in this group, but the performance gap between it and the Nitecore HC75 UHE is substantial. The BIAT maxes out at just 350 lumens with a 150-foot beam, while the Nitecore delivers 3,000 lumens and reaches 630 feet. The BIAT’s IPX4 rating only covers splash resistance, while the Nitecore is fully submersible at IP68. The BIAT does offer value in quantity — two units for a significantly lower combined price — and its lightweight build at 2.47 oz makes it easy to wear. But for users who need serious brightness, long beam reach, and proven durability in demanding conditions, the Nitecore HC75 UHE is in a completely different league. Read our full BIAT Wide Beam Headlamp review to see how it performed in our hands-on tests.
vs. Foxelli MX20B Headlamp Flashlight
The Foxelli MX20B sits at the budget end of this group and is designed for casual, low-intensity use. It tops out at just 165 lumens with a 165-foot beam — a fraction of the Nitecore’s 3,000 lumens and 630-foot throw. It runs on three AAA batteries rather than a rechargeable cell, which adds ongoing battery replacement costs, and its IPX5 rating handles splashes but not full submersion. The Foxelli does offer a long claimed runtime of 45 hours on low and is one of the lightest options at 3.2 oz, making it easy to wear for extended periods. But for demanding work, outdoor adventures, or any situation where reliable high-output lighting matters, the Nitecore HC75 UHE outperforms the Foxelli in every meaningful category. Read our full Foxelli MX20B review to see how it performed in our hands-on tests.
vs. LHKNL Headlamp Flashlight
The LHKNL comes as a 2-pack and is the lightest headlamp in this group at just 1.87 oz per unit, making it an easy wear for casual use. It offers 1,200 lumens and eight modes including a motion sensor, which adds hands-free convenience. However, it runs on a small built-in 1,500 mAh battery with a rated runtime of only 4 to 10 hours, and its IPX4 rating only covers splash resistance. The Nitecore HC75 UHE more than doubles the LHKNL’s brightness, delivers a 630-foot beam versus no listed beam distance for the LHKNL, and backs it all up with full IP68 waterproofing and 84 hours of low-mode runtime. For lightweight everyday use on a budget, the LHKNL offers decent value. For serious performance in demanding conditions, the Nitecore HC75 UHE is in a different class entirely. Read our full LHKNL Headlamp Flashlight review to see how it performed in our hands-on tests.
Who Should Buy the Nitecore HC75 UHE Rechargeable Headlamp
The Nitecore HC75 UHE is built for users who need a serious, high-output headlamp that doesn’t compromise on performance or durability.
Who will get the most out of it:
Those who need maximum brightness and beam distance
With 3,000 lumens and a 630-foot beam throw, the HC75 UHE is one of the brightest and longest-reaching headlamps in its class. Our real-world brightness test recorded a peak lux reading of 10,155 — the highest in our entire test group. If you regularly work in large dark spaces or need to illuminate areas far ahead of you, this headlamp delivers.
Professionals and tradespeople
The E-focus beam adjustment lets you switch between a wide floodlight for close-range work and a focused spotlight for long-distance visibility — all with a single button press. Whether you’re doing electrical work, mechanical inspection, or construction in low light, the HC75 UHE adapts to the task without needing to swap equipment.
Search and rescue and outdoor enthusiasts
The combination of 630-foot beam distance, IP68 waterproofing, SOS and Beacon signaling modes, and 84-hour low-mode runtime makes the HC75 UHE a reliable companion for hiking, camping, hunting, and emergency situations where dependable lighting can make a real difference.
Users who prioritize long runtime
At 84 hours on Ultralow and over 4 hours on full Turbo, the HC75 UHE offers one of the best runtime profiles in this category. If you need a headlamp that can go the distance without frequent recharging, this one is worth serious consideration.
Anyone who wants versatile beam control
The stepless E-focus adjustment is a standout feature that most headlamps in this category simply don’t offer. Being able to fine-tune the beam from a wide flood to a tight spot — or anywhere in between — gives you a level of control that makes a noticeable difference in real-world use.
USB-C users who want fast charging
The HC75 UHE charges via USB-C at up to 18 watts and reaches full charge in approximately 2 hours and 10 minutes. It also functions normally while charging, meaning you’re never fully without light even when the battery is running low.
Who should probably look elsewhere:
Those who want a lightweight headlamp
At 7.37 oz, the HC75 UHE is one of the heavier headlamps in this group. If you need something light for running, trail activities, or all-day wear, the weight may become noticeable over extended periods.
Anyone who needs a handheld flashlight too
Unlike the Olight Perun 3, the HC75 UHE does not detach from its headband for standalone handheld use. If 2-in-1 functionality is important to you, it’s worth looking at alternatives.
Budget-conscious buyers
The Nitecore HC75 UHE sits at the premium end of the price range. If you only need a headlamp for occasional or light-duty use, there are more affordable options in this group that will get the job done without the higher price tag.
Frequently Asked Questions
1. Is the Nitecore HC75 UHE worth the money?
For users who need a high-output, long-runtime headlamp built for demanding professional or outdoor use, yes.

Nitecore HC75 UHE Review: Final Verdict
The Nitecore HC75 UHE is a great light for users who need serious, high-performance illumination for professional or outdoor use. It recorded the highest lux reading of our entire test group at 10,155, lit up our entire outdoor test area like daylight, and passed every durability test we ran — full submersion and a waist-height drop — without any loss of function. The breathable headband and lighter-than-expected weight made it comfortable enough to earn an 8 out of 10 in our comfort test, which is a pleasant surprise for a headlamp at this output level.
The one notable limitation from our testing was the runtime at 1 hour and 42 minutes at full brightness, it’s a reasonable result for a headlamp pushing this level of output, but worth factoring in if sustained maximum brightness is your priority.
Overall, the Nitecore HC75 UHE performed strongly across every test we put it through. If raw brightness, real-world visibility, and proven durability are what you need, it delivers where it counts.
