Milwaukee M18 RADIUS Site Light and Charger with ONE-KEY (Bare Tool)
Product Overview
The Milwaukee M18 RADIUS Site Light/Charger with ONE-KEY (2150-20) is a high-output cordless jobsite light designed to illuminate large work areas while also providing convenient M18 battery charging.
Using one or two M18 battery packs, the RADIUS delivers up to 9,000 lumens of TRUEVIEW High Definition Output with broad 360° coverage. Its adjustable light output lets users balance brightness and battery runtime, while the integrated two-bay sequential charger helps keep additional M18 batteries ready for use.
The light can also operate from an AC power source and supports daisy-chaining, allowing up to six lights to be connected from a single circuit. Integrated ONE-KEY technology provides remote light control, customization, tracking, and inventory management.
Key Features
9,000-Lumen TRUEVIEW Lighting
The RADIUS Site Light produces up to 9,000 lumens of TRUEVIEW High Definition Output. The neutral-white light and even beam pattern are designed to provide clearer visibility across large workspaces.
360° Area Coverage
The light is designed to illuminate a broad work area rather than concentrating light in a single direction. Electronic light control provides both 180° and 360° lighting options, allowing users to direct illumination where it is needed.
Three Output Levels
Three selectable output levels make it possible to adjust brightness according to the application:
High: Up to 9,000 lumens
Medium: Up to 4,800 lumens
Low: Up to 2,500 lumens
The adjustable output also helps extend runtime when maximum brightness is not required.
Runs on One or Two M18 Batteries
The RADIUS can operate using one or two M18 battery packs. Using two batteries provides additional runtime for longer work periods. Batteries are not included with this bare-tool model.
Integrated Two-Bay Sequential Charger
A built-in two-bay sequential charger allows the light to charge M18 batteries, helping reduce the amount of separate charging equipment needed on the jobsite.
AC Power and Daisy-Chaining
The light can be plugged into an AC power source for extended operation. Its plug-in and daisy-chain capability allows users to connect up to six RADIUS Site Lights from a single circuit, making it useful for larger enclosed or temporary work areas.
ONE-KEY Technology
Integrated ONE-KEY technology allows users to:
Customize light settings
Control the light remotely
Track the light
Manage it within a tool inventory
Milwaukee states that the light can be controlled remotely through ONE-KEY from up to 100 feet.
Jobsite-Ready Construction
A high-impact polycarbonate lens helps protect the lighting system against everyday jobsite abuse. The light also carries an IP54 rating, providing protection against dust and water exposure.

What's Included
The 2150-20 bare-tool configuration includes:
1 × Milwaukee M18 RADIUS Site Light/Charger with ONE-KEY — 2150-20
Battery: Not included.
Because the charger is integrated into the light, a separate M18 charger is not required for the built-in two-bay charging function. M18 batteries must be purchased separately.
Lighting Modes
The RADIUS provides three main output levels to help users choose between maximum illumination and longer runtime.
| Mode | Light Output | Best For |
|---|---|---|
| High | 9,000 lumens | Large work areas and maximum visibility |
| Medium | 4,800 lumens | General jobsite lighting |
| Low | 2,500 lumens | Longer runtime and lower-light applications |
The 180°/360° electronic control also allows users to choose how much of the surrounding area is illuminated.
Built-In Battery Charging
One of the main advantages of the 2150-20 is that it combines lighting and battery charging in the same unit.
The integrated two-bay sequential charger can charge compatible M18 batteries while reducing the need to carry a separate charger to the jobsite. This makes the RADIUS particularly useful as a central lighting and charging station during longer projects.
Power Options
The RADIUS can be powered in two ways:
M18 Battery Power
The light accepts one or two M18 battery packs, allowing it to function as a cordless jobsite light without needing an AC outlet.
AC Power
The light can also be connected to an AC power source for extended operation. AC capability is useful when the light will remain in one location for long periods.
The unit also supports daisy-chaining up to six lights from one circuit, helping provide broader illumination across larger work areas.
ONE-KEY Features
ONE-KEY adds digital control and inventory-management functions to the RADIUS.
Users can remotely:
Adjust light settings
Customize operation
Track the light
Manage the light as part of an equipment inventory
The remote control capability operates at distances of up to 100 feet, according to Milwaukee.
Typical Applications
The Milwaukee M18 RADIUS Site Light is suitable for:
Construction sites
Remodeling projects
Electrical work
Plumbing work
Commercial construction
Interior build-outs
Maintenance facilities
Workshops
Temporary work areas
Large enclosed spaces
General jobsite illumination
Its broad 360° coverage makes it particularly useful when a large workspace needs consistent illumination rather than a narrow beam.
M18 System Compatibility
The 2150-20 is part of Milwaukee's M18 cordless system and is designed to work with M18 REDLITHIUM battery packs. Milwaukee's M18 platform includes more than 200 compatible solutions, allowing the same battery platform to be used across a wide range of cordless tools.
Durability and Protection
The RADIUS is designed for demanding jobsite environments with:
High-impact polycarbonate lens
IP54 water and dust resistance
Durable cordless construction
Low-battery indicator
Protected electrical components
The LEDs are designed as a long-life lighting system and are backed by Milwaukee's limited lifetime LED warranty.

Important Product Note
The 2150-20 is a bare-tool model, meaning M18 batteries are not included. The charger is built directly into the RADIUS light.
This model should also not be confused with Milwaukee's smaller 2146-20 RADIUS Compact Site Light, which produces 4,400 lumens and includes ONE-KEY but does not have the same integrated two-bay charger.
Summary
The Milwaukee M18 RADIUS Site Light/Charger with ONE-KEY (2150-20) combines high-output jobsite lighting with integrated M18 battery charging in a single unit. With up to 9,000 lumens, 360° coverage, three brightness levels, AC capability, daisy-chaining, and ONE-KEY connectivity, it is designed to provide flexible lighting for demanding work environments.
For contractors and tradespeople already invested in the M18 platform, the 2150-20 offers a practical way to illuminate a large workspace while also keeping additional M18 batteries charged and organized.
