Arisaka 300 Series E1HT

The Arisaka Defense 300 Series with Malkoff E1HT head represents the pinnacle of compact weapon light design, delivering 500 lumens with 15,000 candela in an ultra-compact package measuring just 2.86 inches long and weighing 3.2 ounces. This diminutive size makes it the ideal solution for short-barreled rifles, PDWs, and pistol-caliber carbines where standard full-size lights extend past the handguard or create balance issues. Despite its compact dimensions, the E1HT maintains respectable throw performance that rivals many older full-size lights, proving that size doesn't always dictate capability.

The Malkoff E1HT head provides Arisaka's modular system with a balanced beam profile featuring good hotspot definition and usable peripheral spill. Running on a single CR123A battery, the E1HT delivers approximately 45 minutes of runtime—impressive for such a small light. The fully potted electronics ensure reliability under recoil, while the CNC-machined 6061-T651 aluminum construction with MIL-A-8625 Type III hard coat anodizing provides mil-spec durability. The 300 Series maintains full compatibility with the SureFire Scout mounting ecosystem, including all tailcaps, switches, and mounting solutions.

For users building compact defensive carbines where every ounce and inch matters, the 300 Series E1HT delivers professional-grade illumination without the bulk of full-size alternatives. It's particularly popular on 7-10" PDW builds, suppressed SBRs, and PCCs where handguard real estate is limited. The mid-tier pricing makes it accessible for users who need compact performance but can't justify premium Modlite or SureFire costs.
