BLUEMAXX
TM
Rechargeable Forensic LED Light
BM500LED
Background and Purpose
The BLUEMAXX™ BM500LED is a rechargeable LED-based illuminator which emits high
intensity blue light at 455nm (nanometers). This wavelength can produce fluorescence in
physiological fluids and other materials treated with certain powders and dyes; in general,
materials having optical excitation bands between 390 and 520nm.
The system has a transparent acrylic orange viewing plate that effectively filters the blue
light, permitting visual observation and photography of the fluorescence effect. The light is
an essential tool for area searches and photography of evidence at a crime scene, and
provides best results when used under subdued ambient lighting conditions.
Unpacking / Set-up
First, fit the orange viewing filter into the groove of the retainer on the head of the
flashlight (shown installed, above).
Next unthread (rotate counter-clockwise) the tail cap from the body tube and install the
battery pack with the Positive (+) terminal of the pack (the raised “bump”) facing toward
the head-end of the light. Then fasten the tail cap by threading it (rotate clockwise) into the
body tube (shown below).
