The same Malkoff Devices heads that we use on the Arisaka 300, 600 and 18650 Series Lights are now available as stand alone upgrades.

E1HTv2 heads fit the single cell Arisaka 300 series and Surefire M300 Scout bodies.

E2HTv2 and E2XT heads fit the two cell Arisaka 600 series and Surefire M600 Scout bodies.

HTL and E2XTL heads fit the larger M600DF, Modlite, and Arisaka 18350 and 18650 bodies.

EX IR heads fit both Arisaka 300 and 600 series bodies, plus Surefire M300 and M600 bodies. They do NOT fit 18350 and 18650 sized bodies.

Recommendations: The new HTL, E2HTv2 and E1HTv2 heads have an exceptional beam profile with a nice hotspot that smoothly transitions to spill. They are a great all-around head, and also happen to be the smallest, lightest, and least expensive heads in our lineup. Almost everyone at Arisaka runs the HTL, E2HTv2 or E1HTv2, dependent on the light body and battery sizes we prefer. Check out this blog post for controlled photos of beam patterns and intensity.

Output and run time specifications:

• HTL - 30,000 candela and 600 out-the-front lumens. 1.1" diameter bezel. Smooth combo beam with throw and spill. Continuous run time is 30 minutes on two CR123 cells or 90 minutes on one 18650 cell.
• E2XTL - 55,000 candela and 500 out-the-front lumens. 1.23" diameter bezel. Very focused beam for maximum distance. Continuous run time is 30 minutes on two CR123 cells or 90 minutes on one 18650 cell.
• E2XT - 55,000 candela and 500 out-the-front lumens. 1.23" diameter bezel. Very focused beam for maximum distance. Continuous run time is 30 minutes on two CR123 cells or 60 minutes on one 16650 cell. 
• E2HTv2 - 30,000 candela and 600 out-the-front lumens. 1" diameter bezel. Smooth combo beam with throw and spill. Continuous run time is 30 minutes on two CR123 cells or 60 minutes on one 16650 cell.
• E1HTv2 - 18,000 candela and 400 out-the-front lumens. 1" diameter bezel. Smooth combo beam with throw and spill. Continuous run time is 45-60 minutes on one CR123 cell.
• EX IR 250 - Infrared only, 250mW output, 5 degree beam angle. Continuous run time is 4 hours on one CR123. Can use one or two CR123 cells, or one 16650 cell. Similar to MAWL C1+ focused illuminator output with twice the area coverage.
• EX IR 700 - Infrared only, 700mW output, 5 degree beam angle. Continuous run time is 1 hour on one CR123. Can use one or two CR123 cells, or one 16650 cell. Exceeds PEQ-15 high output at equivalent illuminator focus.
