Featuring breakthrough focal LED lens technology, the Cliplight 450 produces a 450nm beam of light equivalent to a 100-watt halogen lamp – without any heat output! The light comes in a compact, durable housing which uses solid-state circuitry to achieve up to 11⁄2 hours of light per charge. When not in use, simply plug the unit into an electrical outlet or charge the unit in your vehicle with the included cigarette lighter adapter. The 450nm spectrum is ideal when searching for semen, urine, hair and fibers and for use with fluorescent latent print development chemicals such as Basic Yellow or Ardrox.
