We describe a new portable solid-state ultraviolet (UV) light that should greatly improve the ease and effectiveness of fluorescent detection of scorpions in the field. The design is based on an array of InGaN light emitting diodes (LEDs). It is in-expensive, lightweight, simple to implement, energetically efficient and mechanically rugged. Scorpion cuticular fluorescence excited by an LED array is 13-fold brighter than excitation by previously available fluorescent tube lamps drawing the same current from the battery.
