On construction sites, in technical maintenance workshops, and during nocturnal backcountry navigation, immediate and precise control over beam intensity is essential for operational safety and ergonomic efficiency, as standard pushbutton sequences often introduce delays or mode selection errors. LED headlamp, rechargeable 5W+3W 700Lm 5000K 1800mAh VIDEX VLF-H147 | black – rotary side switch, COB floodlight panel and red light is a professional-grade hands-free luminaire integrating a mechanical rotary selector switch. This engineering solution empowers the operator to effortlessly dial in the required brightness profile with a single fluid movement even while wearing thick work gloves, guaranteeing instantaneous optical adaptation to the working task at hand.

The optical architecture of the luminaire incorporates two specialized light engines: a high-efficiency 5W CREE XPG3 LED emitter for distant spot illumination and a 3W COB diffusion panel for close-quarters flood lighting. In Turbo mode, the apparatus develops 700 lumens of luminous flux with an intensity of 11600 cd, achieving an authenticated throw distance of 185 meters. The 5000K neutral daylight profile accurately preserves surface textures and wire color coding without inducing visual fatigue during prolonged shifts. The directional High mode maintains a commanding 550Lm output for 4 hours, while the wide-angle COB panel (200Lm or 50Lm) produces a soft, uniform field of light for close-up assembly or documentation review without harsh specular glare. Complementing the white beam, the device incorporates an independent red spectrum (Red High, Red Low, and flashing Red Flash), engaged with a 0.5-second press, preserving dark-adapted visual acuity and supporting discreet night reconnaissance or signaling. Current is supplied by an integrated 1800mAh Li-Pol battery (3.7V), rechargeable via a protected USB-C port (5V, 0.8A) in 3.5 hours, accompanied by a 5-level LED fuel gauge on the housing. The resilient polyamide chassis with a tempered glass lens satisfies the IP55 ingress rating against dust and water jets, absorbs 1-meter drop shocks, and features an adjustable friction hinge for smooth beam angling.
