LED HP4 High Intensity, Focusing, UV-A Flashlight

As bright as Micro-discharge lamps costing twice as much

LED HP4 High Intensity Focusing UV-A Flashlight

The NEW HP4 replaces the HP3.


Ultraviolet Light Emitting Diodes / UV LED have numerous applications across various industry fields. Applications include fluorescent magnetic particle inspection (MPI), fluorescent liquid penetrant inspection (LPI), leak detection, contamination detection, and medical applications. The HP4 is unique in regards to its ability to produce HIGHLY FOCUSABLE UV light up to 100'. This allows inspection of large areas in difficult to access locations. Using typical D size batteries simplifies replacement and saves time.


As bright as Micro-discharge lamps costing twice as much*
(LED-HP4+ 48,000 µW/cm2 @ 15" Spot Focus)
The Brightest LED UV Lamp available
