GearWrench GWHL400 400-Lumen Rechargeable Motion-Sensor LED Headlamp

The GearWrench GWHL400 rechargeable LED headlamp delivers up to 400 lumens of focused, hands-free illumination across automotive engine bays, dark crawl spaces, and commercial maintenance environments. Powered by an integrated 3.7V 1500mAh lithium-ion battery providing up to 6 hours of continuous runtime, this professional work light features an innovative wave-activated motion sensor that enables instant on/off power switching without touching the unit with greasy or gloved hands. Outfitted with an IP65 dust- and water-resistant enclosure, two selectable brightness output levels (200 and 400 lumens), a 4-position ratcheting pivot head, an adjustable non-slip elastic headband, and modern USB-C fast charging, it equips automotive mechanics, electricians, and industrial technicians with reliable, precision personal lighting.

Best Used For:

  • Automotive Under-Hood and Undercarriage Diagnostics: Directing shadow-free illumination into cramped engine compartments, wheel wells, and transmission tunnels while keeping both hands on tools.
  • Electrical Panel and Crawl Space Servicing: Navigating dark attics, basements, and unlit commercial utility rooms with focused hands-free beam projection.
  • Industrial Machinery and Mechanical MRO: Performing precision equipment inspections and bearing maintenance in wet, dusty, or oil-prone plant environments.

Key Performance & Safety Features

  • Wave-Activated Motion Sensor: Integrated gesture sensor allows operators to toggle power on and off effortlessly with a simple wave of a gloved hand.
  • Dual Output Brightness Levels: Easily switch between High mode (400 lumens) for maximum visibility and Low mode (200 lumens) for extended battery preservation.
  • IP65 Water & Dust Resistance: Heavy-duty sealed housing withstands high-pressure water jets, rain, fine metal filings, and abrasive jobsite dust.
  • 4-Position Pivoting Light Head: Articulating bracket angles the light beam downward to focus precisely on workpieces without neck strain.
  • Rechargeable Lithium-Ion Power: Integrated 3.7V 1500mAh battery delivers up to 6 hours of continuous runtime on a single charge.
  • USB-C Fast Charging Interface: Universal USB-C charging port ensures fast, convenient power replenishment via wall adapters, vehicles, or portable power banks.
