Mag-lite S4D036 Krypton Handheld Flashlight 4D Cell

Product Description

The MAG-LITE S4D036 is a full-size handheld flashlight built for demanding field use. It uses a krypton bulb powered by four D-cell batteries, delivering up to 10 hours of runtime on a full set of cells. The body is machined aluminum finished in red, providing durability in rough service environments. At 14.75 inches in length and 1.35 pounds, it is a standard full-size torch suited for technicians who need dependable lighting during service calls, inspections, and equipment room work. Batteries are not included and the unit is not rechargeable, so carrying spare D-cells is standard practice in the field.

The S4D036 is well-suited for HVAC technicians, electricians, plumbers, and other trade professionals who work in low-light mechanical spaces, crawlspaces, utility rooms, and equipment enclosures. The 14.75-inch aluminum body provides a firm grip and enough mass to use the light hands-free by resting it against a surface. The 10-hour runtime supports extended service windows without a battery swap mid-job.
