The Pioneer LiFe LF35 is the first of its kind, combining an all new Pioneer SlimLine™ optic with the portability and flexibility of a grab and go light.

The Intelligent Inductive Charger™ with no exposed contacts provides easy, wireless charging, and the built-in battery is lightweight and thermally protected. The LiFe LF35 is just 7.5 pounds, lighter than any other portable area light on the market today.

The Pioneer LiFe LF35 is designed, manufactured, and assembled in the United States.

Don't be left in the dark if you are the first to arrive on the scene.

The Pioneer LiFe™ LF35's LiFePO4 battery will ensure you will never be left in the dark.
During full intensity usage, the battery provides consistent usable lumen output, delivering the brightest illumination possible. For longer jobs, Battery Saver Mode will preserve output by running at a lower intensity
When the battery runs low, the LiFe LF35 will flicker to indicate its need for charge. When 15 minutes of battery life remain, the light will dim to a reduced intensity to preserve output time.

  • Built-in lightweight lithium iron phosphate battery utilizes LiFePO4 technology and features up to 3.5 hours of runtime at full intensity and up to 7 hours of runtime in Battery Saver Mode
  • Battery is built into the unit, making it safe and protected
  • Battery features short circuit and thermal protection
  • With 15 minutes left of battery life, light will dim to a reduced intensity to preserve output time
  • Battery will disconnect when fully charged, preserving the lifecycle of the battery
  • Battery will fully charge in 4-5 hours, maintaining optimal lifespan
  • Battery is rated for more than 2000 charging cycles

Intelligent Inductive Charger™

The LiFe LF35's Intelligent Inductive Charger (IIC™) is wireless and eliminates the need for plugs and wires by utilizing inductive charging technology. Simply place the LF35 into the charging base and it will begin to charge. Without the need for cables, the charger is always at the ready.

  • IIC is specifically designed to work with Pioneer LiFe™ LF35 lights only. If foreign objects are placed on the charger, it will disable itself until the object is removed
  • No open contacts on the charger to compromise charging circuit
  • IIC can be installed on a horizontal or vertical surface
  • Various mounting options for Whelen poles and tripods will soon be available
  • Chargers available in 12 VDC, 115 VAC, and 240 VAC for both U.S. and European markets
  • 12 VDC charger is standard: 5 amps average
  • AC charging is available with adaptor:
  • .5 amps average at 115 VAC
  • .25 amps average at 240 VAC
