Dual-intensity, multi-LED, broad-beam, UV-A LED lamp made for NDT inspection

The QUADRAN™ 365 series multi-LED, dual-intensity, broad-beam, UV-A inspection lamps from Spectronics Corp. are designed for a variety of NDT applications. They feature four ultrahigh-flux, UV-A LEDs for fluorescent inspection, plus a white light LED for flaw location.

Their broad-beam configuration produces a coverage area of up to 6 in. with a minimum UV-A intensity of 2,000 µW/cm² at 15 in. This makes them suitable for hand-held and inline applications.

Two models are available, QDR-365A and QDR-365BLA, each with high-intensity and standard-intensity settings. The high setting produces a nominal steady-state UV-A intensity of up to 8,000 µW/cm², and the standard setting produces a nominal steady-state intensity of 4,500 µW/cm², both measured at 15 in.
