The UltraLite™ ALS One of the most powerful handheld solid-state forensic lights in the industry has just gotten more powerful, doubling its output. The industry standard UltraLite ALS® is now the UltraLite ALS® Turbo. Through the use of light interaction techniques, UltraLite ALS® Turbo helps in the detection of trace evidence, body fluids, fingerprints, blood spatter, gunshot residues, and explosive accelerants. These substances may otherwise be difficult to detect against background materials so evidence can remain unseen.
