The Cloud Defensive MCH Duty HO is a full-size, user-programmable flashlight built for serious hard use—whether you're running tactical operations, working night security, or need a reliable light that can handle anything the field throws at it. At 1,800 lumens with 50,000 candela output, this duty flashlight delivers commanding reach and coverage in a single-hand package, flooding your target area with enough light to overwhelm low-light threats and expose every shadow. Built on a legacy of innovation and durability, the MCH Duty marries brute-force capability with thoughtful field ergonomics.
Durability is where the MCH Duty distinguishes itself. The light head is shrouded in S7 tool steel—the same material used in jackhammer tooling—heat-treated to 51–55 Rockwell and black nitride plated. The result is a flashlight that shrugs off impact and abuse that would destroy lesser lights. An IPX-8 waterproof rating means it's fully submersible to 100 feet for 24 hours, and the bezel ring is field-serviceable, so a broken lens can be swapped in under a minute. The aluminum body is precision-machined 6061-T6 with MIL-spec hard-coat anodizing, and it's ANSI/PLATO FL1 compliant.
Where the MCH Duty gets truly versatile is programmability. You control the output profile—choose from five factory modes or customize your own. Run high-only for maximum output, or dial in low (10%), medium (30%), or very low (5%) paired with high for extended run-times. In low mode, you'll get at least 6 hours of runtime on a single charge, making this equally at home on a nightstand or in your plate carrier. The tail cap is also fully configurable with Cloud Defensive's patented adjustable negligent discharge (ND) protection, letting you adapt pocket carry, belt carry, or clip-free operation to your mission. Powered by a single 18650 rechargeable lithium-ion battery (included), the MCH Duty also accepts two CR123 batteries for emergency dual-fuel capability—though output and runtime will be reduced with CR123s.
This is a light designed for capability and durability first, not minimum size. The 1.40-inch head diameter gives you optimal ergonomics and compatibility with standard light holsters. It ships with a heat-treated, black nitride spring-steel deep-carry pocket clip, a Cloud Defensive UI2 charger, an 18650 battery, and three ND protectors so you can reconfigure the tail as your needs change.
| Output (18650) | 1,800 lumens, 50,000 candela |
| Output (CR123) | 500 lumens, 20,000 candela |
| Runtime (18650, high power) | 60 minutes |
| Runtime (18650, medium power) | 120 minutes |
| Runtime (18650, low power) | Minimum 6 hours |
| Runtime (two CR123, high power) | 65 minutes |
| Light Head Diameter | 1.40 inches |
| Overall Length | 5.35 inches |
| Weight (with battery) | 6.67 oz |
| Weight (without battery) | 5.05 oz |
| Battery Type | 1 × 18650 rechargeable lithium-ion (included); also compatible with 2 × CR123 batteries |
| Material (Body) | Precision-machined 6061-T6 aluminum |
| Material (Light Head Shroud) | S7 tool steel, heat-treated 51–55 Rockwell, black nitride plated |
| Anodizing | MIL-spec type III hard coat |
| Waterproof Rating | IPX-8; fully submersible to 100 feet for 24 hours |
| Color Temperature | Neutral 5000K |
| Programmable Modes | 5 user-selectable output profiles |
| Compliance | ANSI/PLATO FL1 |
| Accessories Included | Cloud Defensive UI2 charger, 18650 battery, 3 ND protectors, deep-carry pocket clip |
The MCH Duty runs on a single 18650 rechargeable lithium-ion battery, which is included in the box along with a Cloud Defensive UI2 charger. It also accepts two CR123 batteries for emergency backup, though output and runtime will be significantly reduced (500 lumens vs. 1,800 lumens). Cloud Defensive recommends unprotected 18650 cells for best performance; compatibility with protected cells is very limited.
Yes—the MCH Duty is fully programmable by the end-user. It ships in Mode 1 (high-only at 100%), but you can select from four other modes based on your needs: Mode 2 (low/high), Mode 3 (high/low), Mode 4 (very low/medium/high), or Mode 5 (high/medium/very low). You can reprogram it anytime your mission changes, and all the parts you need come in the box.
The MCH Duty ships with a heat-treated, black nitride spring-steel deep-carry pocket clip, but it was not designed or optimized specifically for pocket carry. It also includes three patented adjustable negligent discharge (ND) protectors, so you can reconfigure the tail cap for deep-pocket carry, belt carry, or plate-carrier mounting—or remove the clip entirely if you prefer. All the parts needed for these configurations ship with the light.
The MCH Duty features a removable, field-serviceable bezel ring. If the glass is damaged, you can replace the lens yourself in under one minute—no warranty delays, no shipping it back. The glass is the thickest available, but because it is glass, damage is possible. This design lets you stay in the fight.
