The ML300L LED 4D Flashlight provides more than two weeks of continuous light on one set of 4D batteries on eco-mode, making it the perfect reliable partner for home and work, travel and emergencies. With a beam distance of 511 meters (more than 5 football fields) and a strong central beam of 65,407 candela, the Maglite ML300L LED 4D Flashlight is a necessary tool for indoor and outdoor use.

• LED technology: Efficient, bright LED engine delivers stable illumination with low power consumption.
• 4D battery configuration: Designed to operate on four D-sized batteries for robust brightness and endurance.
• 18-day eco mode runtime: Extended burn time in eco mode, reducing the need for frequent battery changes on long trips.
• Durable, water-resistant construction: Built to resist moisture and rough handling in varying weather conditions.

The ML300L provides peace of mind across many scenarios: it’s ideal for home emergencies during power outages, camping and outdoor adventures, roadside assistance, and professional work environments where reliable lighting is critical. Its long eco-mode runtime minimizes downtime and maintenance, while its rugged build stands up to the elements. For best results, keep a small kit of spare batteries and a carrying holster so light is always ready at hand.

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.
