Runtime reaches 37 hours on High and 78 hours on Low. The ML100 3C combines LED Heat-Sink Technology, adjustable spot-to-flood focusing, QuickClik® electronic switching, four programmable function sets, Full Power, Power Save, Momentary, Strobe, and SOS signaling, along with rugged aluminum construction, a knurled grip, IPX4 water resistance, and 1-meter drop resistance.

1. 306-Meter Beam Reach, Up to 78-Hour Runtime & 137 Lumens

The ML100 3C combines a focused long-range beam with extended battery life from three C-cell batteries. At maximum output, the flashlight produces 137 lumens and projects its beam up to 306 meters (approximately 1,004 feet) with 23,393 candela of peak beam intensity.

Runtime is rated at 37 hours on High and 78 hours on Low, allowing users to choose between maximum output and extended operating time. This combination of beam reach, focused intensity, and long runtime makes the ML100 3C practical for emergency preparedness, property checks, outdoor activities, work tasks, vehicle kits, and other situations where dependable illumination over extended periods is useful.

2. LED Heat-Sink Technology with Adjustable Spot-to-Flood Beam Control

The ML100 3C uses LED technology with LED Heat-Sink Technology to help manage heat generated by the LED during operation and support efficient performance. Its optical system provides an adjustable spot-to-flood beam, allowing the flashlight to adapt to different viewing distances and tasks.

Twisting the head changes the beam from a concentrated spot for longer-distance viewing to a broader flood for illuminating a wider nearby area. This provides practical beam control for applications ranging from scanning outdoor areas and property to illuminating workspaces and performing close-range tasks.

• Focus Control: Twist-Head Adjustment

• Maximum Beam Distance: 306 m

• Peak Beam Intensity: 23,393 cd

• Head Diameter: 1.977 in. / 50.216 mm

3. QuickClik® Multi-Function Operation with 4 Programmable Function Sets

The ML100 3C uses Maglite®'s QuickClik® electronic switch to provide quick access to multiple functions through a single control. Available functions include Full Power, Power Save at 25%, Momentary On/Off, Strobe at 12 flashes per second, and an SOS signal using International Morse Code.

Four programmable function sets allow the operating sequence to be personalized around the functions the user wants to access most quickly.

Function Set 1 provides Full Power with one click, Power Save with two clicks, and Strobe with three clicks.

Function Set 2 provides Full Power with one click, Power Save with two clicks, and SOS Signal with three clicks.

Mag Instrument’s (Maglite®) only factory in Southern California is, and always has been. Our entire manufacturing workforce – from product-development engineers to automation specialists to machinists — reports to work there, as it always has. However, we can’t make every part, component, and accessory under our roof.  When we have to go outside, our strong preference is to procure such parts from a maker that is not only domestic but, if possible, local.

But in this age of trade globalization, it is not always practical for the manufacturer of any product of any complexity to procure all the needed parts and components domestically.  In addition to price, there are other and often far more important considerations, like consistent quality and stability in the supply chain.  We have even faced situations where no potential domestic supplier was interested in bidding on a part- or component-supply contract.  And so it is necessary, from time to time, to go overseas for a part or component, as much as we do not like to do that.

So when we say we are “A U.S.A. Manufacturer” whose flashlights are “Built In America,” we do not mean that no part, component, or accessory of one of our flashlights is ever imported. What we  DO mean is that our flashlights are, and always have been, invented, designed, and engineered in America and assembled in and shipped from our American factory where all of the body parts and most of the other parts are made, even if some parts, components, and accessories may need to be sourced from an overseas supplier.  And when our product includes some foreign content, we duly note that on the package labeling.

In this way, we strive to save as many American jobs as possible by keeping our manufacturing as American as it can be and still yield a reliable supply of a product of the quality our consumers demand at a price they will accept.

Mag Instrument, Inc. warrants to the original owner that this flashlight is free from defects in parts and workmanship for ten years from the date of first retail purchase.  Mag or an authorized Mag Warranty Service Center will, free of charge, repair or, at its option, replace a defective flashlight or component. (Mag does not warrant the future availability of particular colors or decorations, and may replace a custom flashlight with a standard flashlight.)  This warranty is in lieu of all other warranties, express or implied.

EXCLUSIONS: This warranty does not cover any of the following: 1. Battery exhaustion; 2. Battery leakage; 3. LED burnout and/or LED module failure; or 4. Damage to or failure of the flashlight or any component thereof due to alteration, misuse, battery leakage or lack of maintenance.

Mag Disclaims any responsibility for incidental or consequential damages. Some jurisdictions (countries, provinces, and states) do not allow exclusion or limitation of implied warranties, incidental or consequential damages and/or limitations on transferability, so the above limitations and exclusions may not apply to you.

HOW AND WHEN TO MAKE A WARRANTY CLAIM: 1. In case of battery exhaustion, do not return the flashlight to Mag, but replace the batteries. 2. If the flashlight has been damaged by leakage of batteries, do not return the flashlight to Mag, but determine what brand of battery caused the damage and follow the battery manufacturer’s instructions about how to make a damage claim. 3. For warranty returns: Send the flashlight (postage or shipping prepaid) to Mag Instrument, 2001 South Hellman Avenue - 50600, Ontario, California, USA 91761-8019, Attention: Warranty/Repair Department, or to an authorized Mag Warranty Service Center. For the location of an authorized Mag Warranty Service Center in your area, consult the retailer where you purchased the flashlight or see the customer service section at www.maglite.com. For your protection and to expedite handling and/or postal claims, we recommend that all returns be insured and sent Certified and/or Return Receipt Requested. Do not send batteries with flashlights.

This warranty gives you specific legal rights, and you may have other rights which vary from country to country, province to province, and state to state. Where any term of this warranty is prohibited by the law of any jurisdiction, such term shall there be null and void, but the remainder of this warranty shall remain in full force and effect. THESE STATEMENTS DO NOT AFFECT THE STATUTORY RIGHTS OF A CONSUMER.
