Our top pick for 2026 is the Neitz NSI-X 100 LED headlight. It is a compact, Made in Japan spot illuminator that mounts on Neitz's NEO loupe frame or a headband, puts a wide 100 mm field on the work at a 400 mm working distance (approximately 32,000 lx on high, per Neitz), and runs up to about 13 hours on its low setting. If you want a smaller, brighter spot from the same light, its sibling the NSI-X 80 is rated at approximately 38,000 lx at 400 mm.
A surgical headlight (also called a medical headlight or LED surgical headlight) puts light along your line of sight, exactly where you are looking, which matters most when you work under loupes. Ophthalmic, oculoplastic, ENT, dental, plastic and general surgeons all buy them, but they weigh the trade-offs differently: some want the widest even field, others the highest intensity in a tight spot, others the longest cordless runtime for a full OR day.
Below we compare seven headlights using only figures published by each manufacturer: three Neitz configurations that US Ophthalmic supplies, and four widely used alternatives from HEINE, Sunoptic, Orascoptic and Integra. Brightness numbers are only comparable at the same distance, so we always state the distance each maker used. We also flag labeling limits that matter to eye-care buyers, because two of these lights carry manufacturer warnings about use on or near the eye.

How to choose a surgical headlight
- Brightness at a stated distance: Lux falls off quickly with distance, so a figure is only meaningful with the distance attached. In this guide Neitz rates at 400 mm, Sunoptic at 40 cm, HEINE at 180 mm, and Orascoptic publishes lumens rather than lux. Compare like with like, or ask for a reading at your own working distance.
- Spot size and whether it adjusts: A wide field suits exam work and open procedures; a smaller spot concentrates light for narrow or deep fields. Some lights let you change spot size on the fly (HEINE 30 to 80 mm, Sunoptic 20 to 110 mm), while Neitz uses a fixed single-focus spot that you choose at purchase (80 or 100 mm) to maximize brightness.
- Color temperature and color rendering: Published color temperatures in this group run from about 5,500 K to 6,500 K. Where a maker publishes color rendering index (CRI), higher values mean tissue colors look more natural. Not every manufacturer publishes CRI, so ask when it matters for your specialty.
- Power, runtime and charging: Check runtime at the brightness you will actually use, not just the maximum figure, plus charge time and whether you can run from mains power or swap batteries mid-list. Head-worn batteries remove the cord but add weight on the head.
- Weight, mounting and loupe fit: Decide between a loupe-frame mount and a headband. The light should sit close to your line of sight and align with your loupes so the spot stays centered in the field. Frame color, padding and adjustment points matter over a long day.
- Labeling and intended use: Read the instructions for use (IFU) before you buy. Integra contraindicates its DUO LED headlight for ophthalmic procedures, and HEINE's IFU excludes illumination of the eyes from the ML4's intended use. Eye-care practices should confirm any headlight's labeling against the procedures they plan to perform.
- Service and parts in the US: A headlight is a daily-use tool. Ask who repairs it, how quickly spare parts such as batteries, pads and cords can be sourced, and whether the unit is new with a US warranty.
#1 · Neitz NSI-X 100 LED Headlight (Neitz)
Best overall: a compact Japanese LED headlight with a wide, even 100 mm field and long low-mode runtime.
The NSI-X 100 is the wide-field version of Neitz's NSI-X LED spot illuminator. US Ophthalmic supplies it on Neitz's NEO loupe frame in Silver Blue, White Pink, White Green or Black Gray, or on a headband. Neitz rates it at approximately 32,000 lx on high, 19,000 lx on middle and 12,000 lx on low at a 400 mm working distance, with a 100 mm illumination field at that distance, and approximately 84,000 lx at 25 cm. A 3W white LED produces cool-white 6500 K light. The battery pack uses a built-in Ni-MH battery rated at approximately 3.5 hours on high, 7.5 hours on middle and 13 hours on low, with a full charge in about 3 hours, and Neitz offers a stand and AC adaptor for longer sessions. Neitz describes the illuminator as small and lightweight to reduce load on the head and nose; the NSI-X and the NEO frame each won a 2014 Good Design Award, and the frame spreads weight across forehead, nose and strap. It pairs with Neitz BL-series loupes from 1.5x to 6.0x. The trade-off is a fixed spot: Neitz uses a single-focus design to maximize brightness, so you choose the field size when you order.
Pros: Wide 100 mm field at 400 mm for exam work and open procedures · Three brightness modes, up to about 13 hours on low (Neitz rating) · Mounts on the NEO loupe frame or a headband; pairs with Neitz BL loupes from 1.5x to 6.0x · Made in Japan, supplied new with US warranty and in-house technical and spare-parts support
Considerations: Spot size is fixed rather than adjustable · About 3.5 hours on high from a Ni-MH pack; plan on the AC adaptor for long lists at full output · No CRI figure in Neitz's published specifications
Best for: Loupe users in eye care, plastics, ENT and general surgery who want a light, wide, even field
#2 · Neitz NSI-X 80 LED Headlight (Neitz)
Best for a tighter, brighter spot: the same NSI-X illuminator focused to an 80 mm field.
The NSI-X 80 uses the same NSI-X illuminator and battery system as our top pick, but focuses the light into an 80 mm field at a 400 mm working distance. Concentrating the output raises Neitz's ratings to approximately 38,000 lx on high, 22,000 lx on middle and 14,000 lx on low at 400 mm, and approximately 100,000 lx at 25 cm, the highest figure Neitz publishes for the NSI-X. Everything else carries over: a 3W white LED at 6500 K, a built-in Ni-MH battery rated at about 3.5, 7.5 and 13 hours on high, middle and low, roughly a 3-hour charge, and an optional stand and AC adaptor. US Ophthalmic offers it on the NEO loupe frame in the same four two-tone colorways or on a headband, and it pairs with Neitz BL-series Galilean and prismatic loupes. Choose the 80 mm version if you work in narrow or deep fields, use higher-magnification loupes with smaller fields of view, or simply want more light on a smaller target. Choose the 100 mm version if you need wider coverage. As with the 100, the spot size is fixed by design.
Pros: Highest Neitz-rated output: about 38,000 lx at 400 mm and 100,000 lx at 25 cm · Smaller spot concentrates light where narrow-field work needs it · Same compact illuminator, battery and frame options as the NSI-X 100 · Made in Japan, backed by US Ophthalmic's in-house repair and spare-parts departments
Considerations: 80 mm field covers less area than the 100 mm version · Fixed spot; you cannot widen it during a case · Ni-MH runtime at full output is about 3.5 hours
Best for: ENT, dental and other narrow-field work, and users of higher-magnification loupes
#3 · HEINE ML4 LED HeadLight (HEINE)
Best for stepless dimming and published color rendering, with an adjustable spot on a headband.
The ML4 LED HeadLight is HEINE's headband-mounted surgical light, built around what HEINE calls LEDHQ illumination and a coaxial design intended to give a shadow-free view. Its strongest feature is flexibility: a slider adjusts the light field from 30 to 80 mm at a 420 mm working distance, and a headband rheostat gives stepless brightness control. HEINE's IFU lists typical illuminance of 90,000 lx at 180 mm without filters, a typical color temperature of 5,500 K and a typical CRI of 92 (minimum 90). Power is flexible too. The belt-worn mPack runs typically 8.5 hours, while the head-worn mPack UNPLUGGED makes the light cable-free with a typical 3.5 hours. HEINE lists the weight at approximately 260 g with the Professional L headband and approximately 460 g with the mPack UNPLUGGED attached. Optional yellow and P2 polarization filters are available, and HEINE offers the ML4 with its HR and HRP binocular loupes. It is made in Germany. Eye-care buyers should note that HEINE's IFU describes the intended use as illumination of the body with the exception of the eyes and warns against shining the light into the eyes.
Pros: Adjustable 30 to 80 mm spot at 420 mm · Stepless brightness control on the headband · Published color data: typical 5,500 K and CRI 92 · Choice of belt-worn or head-worn battery
Considerations: Brightness is rated at 180 mm, so it is not directly comparable to 400 mm ratings · Head-worn battery setup is about 460 g and runs about 3.5 hours · IFU excludes illumination of the eyes from intended use
Best for: Surgeons who want a headband light with an adjustable spot and dimmer for varied procedures
#4 · Sunoptic LX2 LED Headlight (Sunoptic Surgical)
Best for raw output and long OR cases, with the highest published lux at 40 cm in this group.
The LX2 is Sunoptic's battery-operated LED headlight for the operating room. Sunoptic rates it at 80,000 lux at a 40 cm (16 inch) working distance with a 5700 K color temperature, the highest lux figure at that distance among the lights in this guide. The aluminum light module offers a variable spot from 20 to 110 mm and uses a small fan for cooling. Power comes from 14.4 V lithium-ion batteries in a belt holster with variable light attenuation and an audible low-battery warning. The standard battery is rated at 3 hours 15 minutes at full output (6.5 hours at 50 percent); the optional extended-life battery doubles that to 6.5 hours at full output (13 hours at 50 percent). The system ships with two standard batteries, a dual-bay charger and a padded case. Sunoptic's patented Rear Cranial Support (RCS) headband has top and back adjustment knobs and replaceable liners, a Sport Band version is available, and an extended linkage is designed to work with most loupes. An optional SSL-LHD-30 wireless HD camera can be added for 1080p point-of-view recording.
Pros: 80,000 lux at 40 cm, rated at the same 400 mm distance Neitz uses · Widest adjustable spot range here: 20 to 110 mm · Lithium-ion batteries, with an extended option rated 6.5 hours at full output · Optional wireless HD camera
Considerations: Belt holster and cable to the headband · Standard battery runs 3 hours 15 minutes at full output · Fan-cooled module adds a moving part; no CRI figure on the product page
Best for: OR surgeons in spine, ENT, plastics and general surgery who want maximum output and a wide spot range
#5 · Orascoptic Endeavour MD (Orascoptic)
Best loupe-mounted option for all-day runtime, with a published 92 CRI.
The Endeavour MD is Orascoptic's loupe-mounted headlight positioned for the surgical field. Orascoptic describes it as its smallest headlight paired with its longest-running battery pack, and it ships with two battery packs. Output is published in lumens rather than lux: 68, 90 and 115 lumens on low, medium and high, adjusted with a capacitive touch control on the pack. Orascoptic lists a 6500 K color temperature and a 92 CRI, and a focused 2.75 inch (6.99 cm) spot at 12 inches (30.5 cm). Battery life is rated at 11 to 24 hours depending on the setting, with charging of up to 6 hours, and Orascoptic notes the light can be used while recharging. That runtime is the standout figure here and suits practices that operate or examine all day without wanting to manage battery swaps. The trade-offs are a small spot sized for loupe work rather than broad fields, and lumen ratings that cannot be compared directly with the lux figures other makers publish. Because it mounts to loupes, confirm compatibility with the loupes you already own.
Pros: Rated 11 to 24 hours of battery life depending on setting · Published 92 CRI at 6500 K · Small loupe-mounted light; two battery packs included · Can be used while charging
Considerations: Lumen ratings are not directly comparable to lux figures · Small 2.75 inch spot at 12 inches; not suited to wide fields · Loupe-mounted design depends on compatible loupes
Best for: Loupe wearers who prioritize long runtime and color rendering over a wide field
#6 · Integra DUO LED Surgical Headlight System (Integra)
Best comfort-focused OR headband for non-ophthalmic surgery; contraindicated for ophthalmic procedures.
The DUO LED is Integra's current LED surgical headlight; Integra's surgical lighting line also includes the MLX 300 xenon light source. Integra designed it around comfort: dual-layer Cranial Cushion padding, a conforming occipital architecture for individual fit, and an ergonomic headband that Integra says exerts less force on sensitive cranial pressure points, based on its own data on file. Integra also claims whiter light, a larger beam and better color and brightness consistency than the comparison lights in its own testing. Power options are lithium-ion batteries in a holster with a 2-bay or 4-bay charger kit, or a direct power kit with a 20 ft DC cable for cord-powered use. The system is made in Canada. We could not find lux, spot size or runtime figures on Integra's product page, so request the technical data before comparing it with the lights above. Most important for this audience: Integra lists the DUO LED as contraindicated for ophthalmic procedures and warns that it should never be used in ocular surgery or procedures that require direct illumination of the eye. It is a strong candidate for spine, neuro, ENT and general OR teams, not for eye surgery.
Pros: Comfort-focused headband with Cranial Cushion padding · Battery or direct-power operation from one system · 2-bay or 4-bay charger kits for busy ORs
Considerations: Contraindicated for ophthalmic procedures per Integra · No published lux, spot size or runtime on the product page · Performance claims rely on Integra's internal data
Best for: Hospital OR teams in spine, neuro, ENT and general surgery outside eye care
#7 · Neitz NSI-III Headlight (Neitz)
A value-minded Neitz illuminator for BL loupes; ask for the spec sheet before you buy.
The NSI-III is Neitz's other illuminator in the US Ophthalmic lineup, positioned as a versatile, high-powered light for ophthalmic examinations and surgical work with Neitz's BL line of loupes, balancing adaptability and affordability. Like the NSI-X, it is made in Japan and is available on the NEO loupe frame in Silver Blue, White Pink, White Green or Black Gray, or on a headband. Neitz's current website lists the NSI-X as its LED illuminator and no longer publishes NSI-III specifications, so we have deliberately left brightness, spot size and runtime out of this guide rather than guess. If you are standardizing a practice on Neitz NEO frames and BL loupes and want a lower-cost illuminator, it is worth a quote; just ask us for the current spec sheet so you can compare it fairly against the NSI-X and the other lights here. Units are new, carry a US warranty and are supported by our in-house technical and spare-parts departments.
Pros: Fits the same Neitz NEO frame colorways and headband option · Pairs with Neitz BL-series loupes · Made in Japan, supplied new with US support
Considerations: No current manufacturer spec sheet online; request one before ordering · Not listed on Neitz's current website, which features the NSI-X
Best for: Practices standardizing on Neitz loupes that want a value-oriented illuminator

Frequently asked questions
What is the best surgical headlight in 2026? For most loupe users our pick is the Neitz NSI-X 100: a compact, Made in Japan LED headlight rated at approximately 32,000 lx with a 100 mm field at 400 mm and up to about 13 hours on low. If you want maximum output and an adjustable spot on a headband, the Sunoptic LX2 (80,000 lux at 40 cm, 20 to 110 mm spot) and HEINE ML4 (30 to 80 mm spot, stepless dimming) are strong alternatives.
How bright should a medical headlight be? Enough to light your field evenly at your working distance without washing out detail, ideally with a dimmer or multiple modes. Brightness is only comparable at the same distance: Neitz and Sunoptic rate at 40 cm, HEINE at 180 mm, and Orascoptic publishes lumens. A smaller spot from the same light reads brighter, which is why the NSI-X 80 is rated higher than the NSI-X 100.
What is the difference between the Neitz NSI-X 100 and NSI-X 80? They are the same NSI-X illuminator and battery system with a different fixed field. The 100 lights a 100 mm field at 400 mm (approximately 32,000 lx on high); the 80 lights an 80 mm field (approximately 38,000 lx on high). Pick the 100 for wider coverage and the 80 for a tighter, brighter spot.
Can I use an LED surgical headlight with my existing loupes? Usually, but check the mount. Neitz NSI-X lights pair with Neitz BL-series loupes on the NEO frame or a headband, Sunoptic uses an extended linkage designed to work with most loupes, and the Orascoptic Endeavour MD mounts directly to loupes. Tell us your loupe brand and working distance and we will confirm fit.
Are surgical headlights suitable for eye procedures? It depends on the manufacturer's labeling, so always read the IFU. Integra contraindicates the DUO LED for ophthalmic procedures, and HEINE's IFU excludes illumination of the eyes from the ML4's intended use. If you plan to use a headlight on or near the eye, confirm the intended use for that exact model before purchase; we can provide Neitz documentation on request.
Battery-powered or corded: which is better? Battery power gives freedom of movement; check the runtime at the setting you will use and the charge time. Neitz rates the NSI-X at about 3.5 hours on high and 13 hours on low with an optional AC adaptor, HEINE offers belt-worn (typ. 8.5 h) and head-worn (typ. 3.5 h) packs, and Integra offers a direct-power cable as an alternative to batteries.
How do I get pricing on a Neitz headlight? Request a quote from US Ophthalmic. Pricing depends on the configuration (field size, frame color or headband, and loupes), and every unit is new with a US warranty and in-house service and spare-parts support.
The verdict
For most buyers, and especially loupe users in eye care, the Neitz NSI-X 100 is the best all-round surgical headlight in 2026: a compact Japanese LED light with a wide, even 100 mm field, three brightness modes and long low-mode runtime, supplied new with US support. Choose the NSI-X 80 if you want a tighter, brighter spot from the same system.
Among the alternatives, the Sunoptic LX2 posts the highest published output at 40 cm and the widest adjustable spot, the HEINE ML4 offers stepless dimming and an adjustable spot with published color data, and the Orascoptic Endeavour MD leads on runtime for loupe wearers. The Integra DUO LED is a comfortable OR headband for non-ophthalmic surgery, but its labeling rules out ophthalmic procedures. Whatever you choose, compare brightness at the same distance and read the IFU for your procedures.
