Maximal™ ML-3500 Series
Ultra-High Intensity UV-A Lamps

Feature state-of-the-art Micro Discharge Light (MDL) technology with user-friendly design!

 

Produce up to 10 times the UV-A output of conventional HID inspection lamps

  • ML-3500S spot configuration works even in direct sunlight, and has a steady-state intensity of 50,000 µW/cm2 at 15”
  • Environmentally friendly
  • Virtually no emission of harmful UV-B at 15”
  • Instant on
  • Very low visible light emission of under 2 foot-candles (20 lux) to ensure compliance with military and aerospace industry specifications (ML-3500D and ML-3600FL versions)
Optimal efficiency


The Maxima ML-3500 series lamps employ Micro Discharge Light (MDL) technology. The ML-3500S spot configuration produces a steady-state UV-A intensity of 50,000 µW/cm2 at 15" (38cm)—up to 10 times the output of conventional High Intensity Discharge (HID) inspection lamps. Ideal for fluorescent leak detection and for applications where very high output UV is required.

Effective outdoors, even in sunlight

The ultra-high UV intensity of the MAXIMA ML-3500S lamp exposes the smallest defects, cracks, flaws and leaks that previously evaded detection until they become major problems. As a result, inspections are more comprehensive and accurate.

Ideal for Non-Destructive Testing

A flood (ML-3500FL) or diffusing filter (ML-3500D) configuration is recommended for fluorescent penetrant and magnetic particle inspections (FPI and MPI).

Integral bulb/reflector assembly

When replacing the bulb or filter in competitor's lamps, exposed wiring can be a serious shock hazard due to residual current. To eliminate this risk, the Maxima ML-3500 series lamps’ bulb/reflector assembly is designed as a single integral unit with "unexposed" circuitry. The unique design also makes bulb replacement easy (a new bulb/reflector assembly can be installed with just a 1/4 turn). This helps maintain the original output level by providing the benefit of a new reflector whenever the bulb is replaced.

Prefocused bulb

The bulb/reflector used in the MAXIMA ML-3500 series lamps is prefocused at the factory to ensure peak performance. This prevents the loss of output power that may occur due to incorrect, off-center bulb installation during bulb replacement.

Unique diffusing filter available

Due to the ultra-high UV-A intensity of the Maxima ML-3500 series lamps, UV fade of fluorescent penetrants will occur within the "hot spot" of the ML-3500S focused beam configuration after prolonged exposure. The 2F350 diffusing filter, which comes with the ML-3500D lamp, will effectively diffuse the hot spot over a broader area and will significantly lengthen the time before UV fade occurs. A high output flood bulb configuration (ML-3500FL) is also available.

Resistant to magnetic field

Interference from magnetic fields can shut off conventional HID lamps, causing frustrating warm-up delays before restart. The Maxima ML-3500 series lamps are not affected by magnetic fields and thus offers the advantage of continuous, uninterrupted inspection process.

Safe handling

The Maxima ML-3500 series lamps never get hot. A special engineering polymer is used to make the lamp's housing and the contoured handle. In addition, the handle is positioned away from the housing. This allows the entire lamp to remain cool during use to protect against accidental burn injury.

Instant on/ off/ restrike

The Maxima ML-3500 series lamps’ solid-sate ballast offers “instant on” capability. This eliminates the warm up and cool off waiting time (up to 5 minutes) of conventional HID lamps. The ballast also protects against voltage fluctuations that can affect the lamp’s performance.

Super rugged and shock resistant

The lamp head and housing are constructed of a tough engineering polymer to protect against dents, cracks, and scratches. To reduce shock hazard, MAXIMA ML-3500 series lamps come equipped with a 5-wire secondary cord and fully enclosed ballast.

Lightweight, portable, ergonomic design

The lamp head measures only 7-1/2” (19 cm) long and weighs just 2-1/2 lbs (1.1kg). The power cord exits directly from the bottom of the contoured pistol-grip handle, resulting in better balance. An on/off switch is conveniently positioned on the handle. The primary and secondary cords are both 8-feet (2.5 m) long.

Easy maintenance

Flexible, silicone-rubber filter holder can be removed easily without tools for bulb/reflector or filter replacement.

Environmentally friendly

The state-of-the-art MDL bulb used in the MAXIMA ML-3500 series contains 97% less mercury than is found in standard HID bulbs.
