Princeton Tec ECO FLARE - Neon Yellow

The Princeton Tec ECO FLARE in neon yellow is a dual-function emergency signaling light designed for divers, boaters, and water rescue personnel who require reliable personal location and area illumination in low-visibility conditions. This compact, lightweight device functions as both a constant-output locator beacon and a flashing red emergency signal, making it an essential backup tool for anyone operating on or below the water.

The ECO FLARE operates on two standard AAA alkaline batteries and delivers 10 lumens of output with either an ultrabright white LED for area/personal location work or a red ultrabright LED for low-visibility signaling. Both LED configurations exceed 500 hours of burn time per battery set, providing extended operational life for emergency scenarios where every minute of illumination matters. The simple LED swap mechanism allows users to transition between white constant mode and red flashing mode without requiring tools or specialized knowledge, a critical feature when response time is measured in seconds.

This light is built for recreational and professional divers who need reliable redundancy in their signal kit, offshore fishermen operating beyond visual range of shore, and rescue teams conducting night water operations. The neon yellow housing maximizes visibility on deck or in calm water conditions during daylight recovery operations, while the white and red LED options cover night search and emergency protocol requirements. Its compact 4 × 1 × 6-inch profile and 0.3-pound weight make it a practical addition to dive bags, emergency kits, or deck storage without consuming significant space or adding bulk.

Marine lighting that depends on battery power must balance runtime, brightness, and durability under salt-air and moisture exposure. The ECO FLARE's straightforward LED-swap design eliminates complex electronic switching that can fail in wet environments, while the standard AAA battery format ensures field replacement capability anywhere in the world. Serious water operators recognize that a signaling light's value lies not in peak brightness but in consistent, long-duration visibility when conditions prevent other communication methods.
