Multi-LED, Broad-Beam Inspection Lamps for FPT and MPT

Nondestructive testing is utilized in everyday applications where dependable light sources are necessary to examine the structural integrity, safety and reliability in aircraft. Spectronics Corporation (Westbury, NY) manufactures a wide variety of lamps to meet this need.

Their powerful Spectroline® QUADRAN™ 365 S-Series multi-LED, broad-beam UV-A (365 nm) inspection lamps are specially designed to meet ASTM UV-A intensity and wavelength specifications for FPT and MPT. These lamps are available in two models: QDR-365SA and  QDR-365SBLA. To address aerospace industry concerns, both units are “tuned” to a maximum UV-A intensity of 4,500 µW/cm² at 15 in (38 cm). The QDR-365SA comes with a standard faceplate and the QDR-365SBLA comes with a faceplate containing integral black light filters that further reduce the emission of wavelengths longer than 400 nm. Both models use a high/low switch to control the white light LED output. The white light LED’s high-intensity setting is 300 foot-candles (3,229 lux) and the low setting is 10 foot-candles (108 lux).

A certificate of compliance for both wavelength and output measurements is supplied with each lamp. They are engineered with four ultra-hi-flux UV-A LEDs for fluorescent inspection, plus a white light LED for flaw location. Their broad-beam configuration produces an extremely wide coverage area of up to 5 in (13 cm), with a minimum UV-A intensity of 2,000 µW/cm² at 15 in (38 cm). The lamps can be hand-held or used for in-line inspections. Also available are the portable QUADRAN 365 MS-Series of battery-operated AC/DC lamp kits. Along with the QDR-365S-Series UV lamp, these kits contain a rechargeable NiMH battery pack, AC and DC cord sets, a smart AC charger and UV-absorbing glasses. All components are packed in a soft, lightweight carrying case.
