Engineered for Zero-Failure Environments
For over three decades, PROMAG has been the trusted backbone of non-destructive testing (NDT) in safety-critical industries. We design, calibrate, and manufacture advanced LED UV-A solutions that mitigate operational risk, secure regulatory compliance, and empower quality leaders to make flawless decisions when they matter most.

The PROMAG Promise
Precise (365 nm Peak)
Every lamp ships calibrated to a stable 365 nm ± 5 nm peak wavelength, guaranteeing consistent, high-contrast fluorescent indication from the first inspection to the ten-thousandth.
Industrial-Grade Reliability
Rugged housings rated IP66 to IP67 shrug off dust, splash, and repeated impact, keeping lamps performing shift after shift in the harshest field conditions.
Rigorous Compliance
Engineered and individually calibrated against international codes including ASTM E3022, ISO 3059, and JIS, so inspection reports pass audit without exception.
Ergonomic Excellence
Optimized center of gravity and lightweight housings reduce fatigue and wrist strain, keeping inspectors sharp and accurate through long production shifts.
Taiwanese Engineering
Proudly engineered, assembled, and individually calibrated in Taiwan, drawing on world-class semiconductor and optical supply chains for consistency batch after batch.
Your Essential Partner in High-Sensitivity Inspection
Our LED UV-A lamps deliver the optical purity and field reliability demanded by QA managers and Level III inspectors across sectors where a single missed crack can lead to catastrophic failure.
MPI Inspection
Magnetic Particle Inspection (MPI)Under PROMAG's stable UV-A output, fluorescent magnetic particles concentrate at leakage flux fields, turning invisible surface and near-surface cracks into sharp, high-contrast indications an inspector cannot miss.
FPI Inspection
Fluorescent Penetrant Inspection (FPI)Consistent 365 nm illumination pulls trapped fluorescent penetrant out of surface-breaking discontinuities, making even the finest fatigue cracks and porosity glow reliably under inspection light.
Where PROMAG LED UV-As Ensure Safety
Five sectors where a missed indication is never an acceptable outcome.
Aerospace & Defense
Detecting fatigue cracks and casting porosity before flight-critical components enter service.
Oil, Gas & Energy
Verifying weld integrity across pipeline girth welds and tank shells where a missed indication risks catastrophic failure.
Transportation, Automotive & Rail
Screening safety-critical drivetrain and undercarriage parts for surface fatigue during high-volume production and periodic maintenance.
Manufacturing & Metal Fabrication
Confirming forging laps, casting porosity, and weld repairs meet spec before parts move downstream.
Steel Mills & Heavy Industry
Inspecting structural welds and load-bearing components under continuous, round-the-clock duty cycles.
PROMAG UV-A Product Lines
Nine models across four categories — overhead, flashlight, handheld and headlamp. Every lamp runs a 365 ± 5 nm optimized UV-A spectrum, holds visible light to ≤ 20 lux at 38 cm, and emits no UV-B or UV-C.
CROWN Overhead
Learn MoreOne fixture covers both fluorescent and visual inspection. An integrated white-light mode eliminates the need for equipment changes at the inspection station. Features adjustable UV-A intensity displayed as a live percentage and IP67 sealing for washdown areas.
ALPHA Ⅰ Overhead
Learn MoreThe most compact overhead lamp in the range. Digital intensity display and a low-temperature body that saves power and extends LED life. An optional remote control allows adjustment from floor level, with no ladder work mid-inspection.
ALPHA Ⅱ Overhead
Learn MoreBuilt to grow from one head into a full inspection canopy. Series power-supply connection lets multiple lamps run from a single supply. An active cooling fan module is available to hold output steady through continuous long-hour runs.
HANSA Overhead
Learn MoreCoverage that grows with the part. Slave units dock to the main unit on the short side. A rugged aluminium body with passive fanless cooling operates at 30–50 °C, and at just 6 cm deep, this is the slimmest overhead lamp in the range.
PROUV 50 Flashlight
Learn MoreThe lightest lamp PROMAG makes, and the only flashlight certified to all three aerospace standards together. Full brightness the instant it is switched on, with no warm-up — built for MRO and flight-critical component inspection.
PROUV 100/200 Flashlight
Learn MoreThe highest certified output in the PROMAG range. Focused into a tight beam for small welds and awkward geometry. Anodised aluminium body with an antioxidant filter that keeps UV-A output stable over the life of the lamp.
VICTORY Ⅰ Handheld
Learn MoreFour high-output UV-A LEDs with a high/low intensity change-over switch. Battery gauge, three-position switch and natural air cooling. Runs on a 12 V Li-ion pack or straight off mains, with white-light versions available.
VICTORY Ⅱ Handheld
Learn MoreThe same body as VICTORY Ⅰ, sealed and silenced. IP64 against dust and splash, and fanless mechanical cooling with no moving parts to fail. Battery runtime doubles to three hours continuous.
OWL-80 Headlamp
Learn MoreFrees both hands for component handling. The rear-mounted battery balances the weight and keeps cables clear of the work, the head tilts through 90°, and it wears directly on the head or clips to a safety helmet. Two batteries ship as standard.
One fixture covers fluorescent and visual inspection. Samsung LEDs, settable intensity with live percentage display.
Models: CRW-AS1 · CRW-AS · CRW-SD · CRW-AD — < 5,000 to ≥ 8,000 µW/cm²
Learn More
The most compact overhead lamp, with digital intensity display. Optional remote adjusts it from floor level.
Models: ALPHA-AS1 · ALPHA-SD · ALPHA-AD — UV-A only
Learn More
Lamps run in series off one power supply to build a full canopy. Active cooling fan module available.
Models: ALPHA Ⅱ-AS1 · ALPHA Ⅱ-SD · ALPHA Ⅱ-AD — UV-A only
Learn More
Slave units dock to the main unit to expand coverage. Aluminium body, fanless, only 6 cm deep.
Models: HANSA-AS1 (< 5,000) · HANSA-SD (≥ 8,000 µW/cm²)
Learn More
Four high-output UV-A LEDs with high/low switch and battery gauge. Runs on battery or mains.
Models: VIC1-AS1 · VIC1-AS · VIC1-SD — white light on AS and SD
Learn More
Same body as VICTORY Ⅰ, sealed to IP64 and fanless with no moving parts. Runtime doubles to 3 hours.
Models: VIC2-as1 · VIC2-as · VIC2-sd — white light on as and sd
Learn More
Frees both hands for confined-space and in-situ work. Rear-mounted battery, 90° tilt, two batteries supplied.
P7213: UV-A only · ≥ 10,000 µW/cm²
Learn More
The lightest lamp in the range, full brightness instantly. The only flashlight certified to all three aerospace standards.
P7310: UV-A only · < 5,000 µW/cm²
Learn More
The highest certified output in the range, in a tight beam for small welds and awkward geometry.
P7313: ≥ 10,000 µW/cm², Ø 11 cm · P7314: ≥ 20,000 µW/cm², Ø 9 cm
