Mars 79220 3D-3C Krypton Dc Bulb

Product Description

The MARS 79220 is a 3D-3C Krypton DC bulb designed for use in flashlights and portable lighting tools commonly carried by HVAC technicians, plumbers, electricians, and other trade professionals. MARS, short for Motors and Armatures, Inc., is a well-known supplier of components and accessories to the trades, and the 79220 continues that tradition by delivering a reliable, high-output bulb built for demanding field conditions. Krypton bulbs are a step above standard incandescent bulbs. They use krypton gas inside the glass envelope instead of a vacuum or cheaper fill gas. This allows the filament to burn brighter and last longer while drawing the same amount of power from the battery. For trade professionals working in crawl spaces, attics, mechanical rooms, and tight utility chases, a brighter and longer-lasting bulb means better visibility and fewer interruptions on the job. The 3D-3C designation tells you exactly how this bulb is rated. The 3D refers to compatibility with flashlights that use three D-cell batteries. The 3C refers to three C-cell battery compatibility as well, depending on the flashlight design. This dual compatibility makes the 79220 a versatile replacement bulb to keep in a service van or tool bag. Replacing a worn or blown bulb is a quick fix that restores full light output without buying a new flashlight. Keeping a spare on hand reduces downtime. The MARS 79220 is a direct drop-in replacement for compatible flashlight models, making it easy to swap in the field without tools. Trade pros searching for a krypton flashlight bulb replacement, 3D 3C bulb, or MARS lighting accessory will find the 79220 to be a dependable and cost-effective solution.
