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

QUADRAN™ 365 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. For increased flexibility, a unique dual, high/low white light output control.

QUADRAN™ 365 S-Series lamps are available in three models (QDR-365SA, QDR-365MSA, and QDR-365MSBLA).

The QDR-365MSBLA and QDR-365MSA come with a Battery Pack for Mobility.

The QDR-365MSBLA is equipped with a faceplate containing integral black light filters that reduce the output of wavelengths longer than 400 nm.

UV-A Beam Profile


Typical wavelength output profile of QUADRAN™ 365 S-Series lamps with and without black light filters.
As the wavelength of the QUADRAN™ 365 S-Series moves into the visible light range, the black light filters significantly reduce the output of the lamp at 400 nm.
