QUADRAN™ 365 Series Multi-LED by Spectronics®

QUADRAN™ 365 Series

Versatile, Dual-Intensity, Multi-LED, Broad-Beam NDT Inspection Lamps!

QUADRAN™ 365 S Series NDT lamps feature four ultra-hi-flux UV-A LEDs plus a convenient white light LED to quickly switch between fluorescent inspection and flaw location. A unique dual-intensity feature provides both high and standard UV-A and white light output for added versatility.

The lamps´ broad-beam configuration produces an extremely wide coverage area, making them ideal for both handheld and in-line applications. Two models are available either with or without integral black light filters to meet your specific inspection requirements.


  • Choice of two models, both with a maximum standard UV-A intensity of 4,500 ?W/cm2 at 15 inches (38 cm)
  • Extremely large coverage area of up to 5 inches (13 cm), with a minimum UV-A intensity of 2,000 µW/cm2
  • Low visible light emission — less than 2 foot-candles (22 lux)
  • Conveniently located rocker switches for quick and easy control of light sources
  • Built-in fan keeps LEDs cool to maintain optimum light output during extended use
  • Rubber bumper with Borofloat® glass lens protects LEDs from damage
  • Rugged, modular construction allows for easy field serviceability
  • Lamp handle pin receptacle allows for easy attachment of various Spectroline® mounting accessories for in-line inspection applications (accessories sold separately)
  • Choice of standard 8 foot (2.4 m) or extra-long 20 foot (6.1 m) heavy-duty power cord with AC plug and rubber boot. Also available: Optional industrial power supply or in-line power supply with cord sets (sold separately). All power supplies available in 120V, 230V, 240V and 100V models.
  • Meet ASTM UV-A intensity and wavelength specifications for FPI and MPI
  • Certificate of compliance for both output and wavelength measurements supplied with each lamp
  • UV-absorbing spectacles and soft carrying case included
