The Fenix E04R is a compact clip-on light built for hands-free use in the field, on the job, or anywhere a secure, versatile mount matters. Its 360-degree rotating 16mm clip and 40-degree tilt angle let you position the beam exactly where you need it, whether clipped to a shirt pocket, gear strap, or hat brim. White output reaches up to 300 lumens with a beam distance of 151 feet (46 meters), backed by up to 23 hours of runtime for all-day and overnight reliability. The side-mounted warning light adds serious utility with red/blue flashing, red flashing, blue flashing, RGB pulse, and RGB chase modes, making the E04R a capable signal and safety light as well as a task light. Recharging is handled through a waterproof USB-C port, and electronic lockout prevents accidental activation in a pack or pocket.

Built to IP66 waterproofing standards and rated for 1.5-meter impact resistance, the E04R holds up to rain, dust, and the routine punishment of daily carry. Whether you're a first responder who needs a visible warning presence, a tradesperson working in tight spaces, or an outdoor user who wants a lightweight backup light, the E04R delivers a practical combination of output, runtime, and adaptability in a clip-on form factor that stays out of the way until you need it.
