Magnaflux UV Lamp Comparison: Which Black Light is Right for Your NDT Inspection?
Share
In Non-Destructive Testing (NDT), your eyes are only as good as your lighting. Whether you are performing Magnetic Particle Inspection (MPI) or Fluorescent Penetrant Inspection (FPI), the quality of your UV-A light source largely determines whether you spot a critical indication or miss it entirely.
Magnaflux has long been the gold standard for NDT black lights, having successfully transitioned from the hot, fragile mercury-vapor bulbs of the past to modern, cool-running LED technology. With several models available, how do you choose?
Below, we compare the primary Magnaflux LED UV lamps available at NDT Supplies—including the new Rechargeable UV-A 365 Torch—to help you decide which one fits your inspection process.
1. The Aerospace Standard: Magnaflux EV6000
Best For: Aerospace components, critical safety parts, and strict compliance environments.
The Magnaflux EV6000 is the flagship handheld unit designed specifically to meet the rigorous requirements of the aerospace industry. If your facility is audited by Nadcap or must meet Rolls-Royce RRES 90061 specifications, this is the lamp you need.
- Beam Width: 9 inches (23 cm) — 33% wider than standard handhelds.
- Intensity: 5,000 µW/cm² maximum.
- Key Feature: Sealed, fan-less construction (IP65 rated) prevents dust and water ingress, making it durable for wash stations.
- Certification: Fully certified to ASTM E3022 and RRES 90061.
2. The Industrial Workhorse: Magnaflux EV6500
Best For: High-volume industrial inspections, field work, and dual-light applications.
While the EV6000 focuses on strict aerospace compliance, the Magnaflux EV6500 is built for versatility and raw power. It features a dual-light system, allowing inspectors to switch between high-intensity UV and bright white light with the push of a button—perfect for locating defects and then immediately documenting them.
- Beam Width: 10 inches (25 cm) — The widest coverage in its class.
- Intensity: 7,000 µW/cm² (High Intensity).
- Key Feature: Built-in white light LED for visual inspection and safety.
- Certification: Meets ASTM E3022 and ISO 3059 standards.
3. The Pocket Powerhouse: Magnaflux UV-A 365 Torch
Best For: Tight spaces, quick field checks, and difficult-to-reach areas.
Sometimes you can't drag a cord into a boiler or engine bay. The Magnaflux UV-A 365 LED Torch Light packs inspection-grade performance into a compact, battery-operated package. It is small enough to fit in your pocket but powerful enough to meet ASTM standards.
- Beam Width: Focused 3-inch (7.6 cm) spot for intense inspection.
- Intensity: 6,000 µW/cm².
- Key Feature: 8-hour battery life with USB-C charging and an instant-on "click" switch.
- Certification: Meets ASTM E3022 specifications.
4. The Stationary Solution: Magnaflux ST700
Best For: Fixed inspection booths, mag particle benches, and large parts.
Stop holding the light and start inspecting. The Magnaflux ST700 is an overhead, stationary flood lamp designed to cover large areas. It allows inspectors to use both hands for manipulating parts, significantly speeding up workflow on mag benches.
- Beam Width: Massive 20 x 26 inch (50 x 66 cm) coverage area.
- Intensity: 7,000 µW/cm².
- Key Feature: Can be linked together (daisy-chained) to cover extremely long parts or large inspection booths.
- Certification: Certified to ASTM, AITM, RRES, and Nadcap standards.
