Overview

Mounting an LED light on the head or a hard hat is the job of this Milwaukee REDLITHIUM lamp. A lithium ion battery is included, and a rectangular light housing is mounted on a cylindrical body with a knurled finish.

The rechargeable battery and USB charging mean there are no disposable cells to carry. Waterproof construction suits outdoor work. The limitation is detail: the listing gives no mode list, beam type or attachment method.

Who it's for

Electricians, contractors and outdoor workers who want a rechargeable light with a long runtime. Shoppers who need a detailed mode list or confirmed hard hat fit should check the maker information.

Pros and cons

Pros
  • Rechargeable lithium ion battery
  • High maximum output
Cons
  • Attachment method not described
  • Beam modes not listed
  • Single color option

Performance notes

Output and runtime trade against each other: the maximum lumen figure is a peak, and the five hour runtime applies to the setting the maker used for that rating. A lithium ion cell supplies steady output, and charging over USB refills the battery without removing it.
