The SpectrolineOPTI-LUX 400 (P/N OLX-400) is a powerful rechargeable violet light LED leak-detection flashlight. It emits less visible light than standard blue light inspection lamps, so refrigerant leaks are easier to spot, thus saving valuable diagnostic time and money. The light OPTI-LUX 400 features a high-output violet light LED that causes dyes to fluoresce more brilliantly and with greater contrast. It has power comparable to high-intensity 150-watt lamps and works with all popular universal/POE dyes. The light is compact and lightweight, allowing it to get into tight and cramped areas that larger lamps can’t. It features an inspection range of 25’ or more. A rugged corrosion-resistant anodized lamp body stands up to years of heavy use.
