LED Leak Detection Flashlight


Spectronics Corporation has introduced the OPTIMAX™ 400 — an economical, violet light LED leak detection flashlight. It emits less visible light so industrial fluid leaks are easier to spot, saving technicians valuable diagnostic time and effort. The OPTIMAX 400 features a high-output LED that causes fluorescent dyes to glow more brilliantly and with greater contrast than conventional lamps. 

The flashlight’s pre-focused beam optimizes fluorescent response without any adjustments needed. With power comparable to high-intensity 150-watt lamps, it works well with Spectroline® OIL-GLO™ 33 (green), OIL-GLO™ 44 (yellow/green) and OIL-GLO™ 50 (red) oil-based dyes, as well as WATER-GLO™ 802 (green) water dye. The OPTIMAX 400 is engineered with “instant-on” operation. Its cordless, compact design allows it to get into tight, cramped areas larger lamps can’t. A rugged, corrosion-resistant, anodized lamp body stands up to years of heavy use. Powered by standard AAA batteries (included), this unit features an LED with a 100,000-hour service life. The flashlight comes with a lanyard, belt holster and fluorescence-enhancing glasses, all packaged in a full-color hanging clamshell.
