Spectronics Corporation has introduced the Spectroline OPTI-LUX™ 400—a rechargeable, violet light LED leak detection flashlight. It’s designed to emit less visible light so industrial fluid leaks are easy to spot by their bright fluorescent glow. The OPTI-LUX 400 features a high-output violet light LED that causes dyes to fluoresce more brilliantly and with greater contrast than with standard blue light inspection lamps. It has power comparable to high-intensity 150-watt lamps and works with Spectroline OIL-GLO 33 (green), OIL-GLO 44 (yellow/green) and OIL-GLO 50 (red) oil-based dyes, as well as WD-802 (green) water dye. The LED has a 100,000-hour service life.
